I just meant that your posts are difficult to read fluently. Rigidity and integrity are similar but different. One implies strength the other implies ample ability for the task at hand. Sort of like university vs. community college. As long as the welder boxes in the section of the spare well he is removing it will be fine and potentially stiffer than before. For instance on my truck's frame the area over the rear axle was cut out for vertical clearance but the horizontal section was replaced further up and connected with the other side of the frame, aka boxed in. Not only does it improve the ride and clearance issue, it is much stiffer than before. Factory frame setup is a C channel not fully boxed unfortunately.

This example applies to your application, otherwise I wouldn't have relayed it. Seems like a waste of money to me and reduces the cars re-sale value drastically. Hopefully your goal is not weight savings (1 muffler vs. 2), then its definitely a minimal return on investment.

 

Understood! Dictionary are "Great", when words have to be distingush or comprehended. Your expert opinion is very much welcome as applicable information. An I'm sure you wouldn't relay any advice, if it wasn't to the best of your knowledge, as a Car Enthusiast. But like I mention earlier, there's several Professional Individual involved in this matter, that declare totally different facts. Which I wouldn't have relayed or provided in this post as well, if it wasn't applicable. Waste of money, reduce car resale value, etc...... WOW! This isn't my first automobile, that has been modified or refab; an with all do respect, our finances/investments are completely different. The cars that I trade in or resale, recieve a considerable amount of money back to satisfy my purpose/investments. So, on that note, Thanks! For any information that you had to express, because it was definitely looked over and considered. I'll post follow-up pics of this project, as soon as it begins. Thanks!

In the first video and second pic it looks like the tips of the mufflers and way under the rear of the bumper. Will they eventually stain the rear bumper from the exhuast? Is it worth all that fab for the gains?

 

Your correct! When the exhaust was first set-up, the hangers where really tight and needed adjusting, which was completed several days later. An, I guess the answer your looking for regarding the fabrication project is No! But in my case the answer is, Yes! It's worth it! This has been performed on several vehicles of mine in the past. An the results turned out spectacular, I know a lot of you guys here don't like to alter or modify much on your Maxima, to a certain extent. But if you have someone that can build a car from the ground up, an fabricate just about any automobile. You tend to break the Status-Quo..... especially when your fabricator does "Great" work.
An where did you get your information that this was just for some sort of gains in performance only?


Redls1! Quick question, your maxima looks pretty cool; are those 17s?
Because my neighbor really likes them a lot. What brand are they?

 

You're > your in this instance.

Those cannot be 17's.

 

No information, just a question. You just clarified that it was not all for performance but you liked the look. Its not that we dont like to modify our cars but looking for the benefit of all the trouble and cost going into such modification. In yours it was the looks also added. The rims are 20" Katana Desire.

 

What? You have to elaborate, just a bit more.
Is that smiley thing picking it's ear or something, maybe rubbing the side of it's head? Funny Character!!!!

Redls1! Thanks for verifying the correct Brand/Size Wheel that you currently have on your vehicle.

Hah, you are too funny. A dictionary doesn't help with grammar and spelling errors let alone fluidity of ones sentences. I am very happy you make more money than I do and don't mind losing it on the trade in or re-sale. I won't mention what I do for a living or my work experience, you have your panel of experts to consult with as is. If you are building a wild show car that is one thing but not being able to carry a spare AND groceries would make a vehicle a lot less desireable to the average person. But good thing you have that Platinum American Express to purchase run flat tires with.

 

Unbelievable, the advice that you preach with such confidence should definitely be practice amongst yourself. An I beg to defer that a really good published Websters Dictionary doesn't assist in proper grammer, spelling errors, an as you stated previously "Fluidity" of ones sentences. My deepest apology that my grammatical self-contained speech doesn't meet this very awkward desire of yours to "Please". Gotta admitt! Where suppose to be discussing rides, viewing pics, and enjoying the forums. I guess that includes critics, funny characters, weirdies (yes that is a word), and a bunch more that the world offers here on this site. What you do for a living really doesn't matter to me, so I appreciate you containing that information for yourself. My Platinum Express Card (correction "American Express Card"), Investments, trade in car value, spare tire, make more money than you comment and my favorite of them all "Groceries". Dude!!! REALLY? I'm very well off in the common sense category when it comes to living an making decisions on a daily bases "Thank God". If these minor issues baffle and create tension for you. Huh, I really don't know what to say @ this point in time, but that sounds like a personal problem. Your opinion/advise regarding the custom exhaust was briefly observe a definitely looked over. Just because I didn't marvel over the information that you had to offer doesn't mean you have to display your wonderful sense of humor. OH! You did mention happiness for me. So, I guess I'm happy for you as well in all your endeavors. Are we even "Now" because I'm a very joyful/happy person who doesn't get upset very easy? It actually takes quite a bit to get me annoyed but boy do I love debate, so discussing any topic off the top of your brain is fine by me. Or Not?



Pictures of another maxima with a similar Custom Exhaust Fab(Fabrication) will be posted up in a few days for anyone that wants to view this awesome exhaust concept.

common now guys... dont worry be happy.

 

BigPete! Life is good everyday even if others try to alter it in any form.
Trust me I sleep very well @ night not follow the Status-Quo of others.


What's new with your ride?

 

not much, holidays cleared me out. check my pics thread

 

That was a much easier to comprehend post. Seems like you took your time to type and pause allowing for proper brain to fingertip synapse transmission. Thank you, I really appreciate it. Carry on with the Maxima hack up.

 

LOL! THERE WE GO was waiting for a reaction like that to eventually occur being that your wonderful sense of humor has been present, Well @ least since my first post regarding this whole exhaust matter. An the continuation of "My" automobile hack up project will proceed as scheduled so Thanks! for your much needed approval/blessing. Well, please excuse my proper brain it has rounds here @ the hospital to complete but it was very interesting chatting with you once again. Some of the R.N's here find your post very amusing as well as Oops...... gotta go. Have a good one an be safe.

 

Ah, then I'm glad I stuck some medical terminology in there. What a coincidence. Do you post so eloquently on WebMD as well?

 

I Lol'd at this thread.

 

OK! Several of us are back to view your very humorous replies towards a matter that tends to be very immature yet amusing. An I guarantee when a time comes where someone has to possible save your life one day. The last thing you'll be contemplating is what type of exhaust, Credit Card, Groceries, spare tire, an what punctuation skills they possess. I didn't realize you were the first perfect man or women in the world not to make any common errors what-so-ever. I'm surprise you have some familiarity with WebMD but they do advertise on television frequently, so I understand the connection now. Like I mention previously about this site is that members should enjoy the forums, positive feedback, an to share there unqiue experiences as a Maxima owner. But there's always a "Joke" here & there to offer some humor or maybe just static for some form of attention. Learn that during my Psych rotations many years ago. Well, it's also a pleasure chatting with you but I have competition in 3 months an the "Gym" is awaiting.

 

QwikKota why don’t you visit this forum http://www.englishforums.com/
I’m sure some people on that forum would greatly appreciate all your tips.
This is Maxima forum so why don’t you just relax with all the grammar.

 

This forum is so funny. It's crazy how much time people put into bashing others ideas that they dont agree with. Instead of just simply saying I don't like it or that's not for me people go to the next level. If you don't like fine say so but I think all the other remarks are not needed. We all don't have the same sense of style if we did all our cars would look the same. If he wants to hack up his car let him it's his it doesn't bother me and it shouldn't bother anyone else. Especially how much it will be worth after if it's not my car I really wouldn't be worried. And who cares how much money anyone makes what is this the Forbes forum? Most of the threads on here always end up with 2 or more people arguing over something that minute.

 

You are here now...

 

So really. How was the ebay exhaust?

 

Chernmax! For some reason while discussing a modification that I'm considering in the near future, cause a sudden hormonal episode amongst a member here. Slightly baffling @ first but then I realize that some ppl require more attention then others. But like I mentioned previously there is a gentleman that lives in my neck of the woods that has had this mod perform and it turn out remarkable. Let's get to hacking.....


BigPete! Are you going to attend the "Huge" South Florid Meet?



Redls1! I'm not a cheap man what-so-ever when it comes to things in life. I no you didn't imply that @ all, just trying to make a point here. Several friends of mine have owned this exhaust set-up for over two years now. Without any complications, an on that note I occassional run into another member here in town with the actually Greddy Exhaust set-up. Only difference is the logo, even a few reputable muffler shops here in town approved of the ebay cat-back exhaust as well as the Greddy set-up. Quality doesn't have to cost $600 to $800 always to mean it's better, an if you really think about it your just paying mark-up anyways. I mean come on do you think companies like Borla or Greddy would pay that price wholesale for a bolt-on unit. Can you say "Mark-Up? I have "NO" reason to steer anyone into the wrong direction regarding this unit just stating facts as an actual owner. Trust me you would'nt be wasting your money, Honestly!!!


This doesn't mean Borla, Greddy, MagnaFlow or even Cattman Exhaust aren't exceptional Exhaust set-ups. All this Brands are very good.

 

Yes I love my Greddy Exhaust

I dont know about that Ebay exhaust though.....I know for damn sure its better than our stock exhaust. That crimped section before the split is ridiculous.

 

I agree with you 100% about Greddy Exhaust set-up it truly is a great product. I really wish I could show you side by side comparison. Well, you know what? My ride is on four jake stands as we speak so tomorrow I'll snap a few underneath the car pics for you guys. It's actually good quality material along with excellent performance and exhaust acoustics. One other thing your ride looks spectacular bro.What suspension set-up do you currently have on your maxima? Excellent over-all appearance!

 

Awesome - post up the pics when you can. Thank for the comment - I'm on Ksport coilover suspension. I actually got a few new things for the ride last week so I'll post up some new pics soon. Hopefully.

 

Presense, you're a well spoken person and I'm sure you will have a lot to contribute in this forum. In time people will know you better and grow to understand you're not a bad guy (I'm fairly edumicated so I understand). Keep the disagreements in PM when possible, maintain the high ground, and post through the distractions so we can stay on topic.


LOL unless of course it's your thread, then flame away...

 

First good luck on the 350Z muffler install I also thought of it but was to $$$ to custom for me. But man I love the sound they make..
Ok more exhuast talk. I spoke to local custon shop here in MA. Lou's Custom for those in the area and they quoted me 150$ for a cat back ( 2.5 inch all the way)to the stock mufflers. Question should I keep the stockers are do they flow enough. I will probally never go FI but do plan on getting the headers when they come out. Also if I replace the stock mufflers will it be to loud. Another member with the wifey to think about. She hated my EVO with 3 inch Tanbe, but loved my 350Z with the Tanbe. So I guess there is a middle ground I just need to find it. Thank you.. Mike

 

The internet will be the downfall of properly written and spoken languages, lol. I'm sorry I take the time to make sure my sentences are correct and spelling is proper etc. Hell, most email editors and forums will underline mis-spelled words. I'm just saying it makes posts easier to understand and get points or questions/problems across to readers so the replies can be accurate and helpful. I apologize if that doesn't make sense. I am also confused on how its any different than when someone posts in all caps or doesn't use a period and creates the worlds longest run on sentence. Most users here are quick to point that out as you are no doubt aware. Back to the muffler talk!

 

Arrrr ! Let’s talk about mufflers.

 

What the heck happened here?

Joshua

 

After reading this entire thread, and laughing, I'd like to point out that the "back pressure" theory of exhausts is a myth. "Back pressure" has nothing to do with engine torque; flow velocity does. Back pressure only mattered before cars could adjust fuel delivery; no modern car has this issue. "Back pressure" refers to obstructions in piping, which we want to avoid. By enlarging the size of the pipe, you lose the optimum flow velocity because the exhaust pulses hit into each other (by reflecting off of the pipe) and slow down on the way out, robbing the car of hp and torque. A smaller pipe will create back pressure (obstruction) but its not the back pressure that creates the problem, its the lack of velocity of the gases. Thus, back pressure is an effect created by piping issues, but the true symptom is velocity. Really, you want to remove the obstructions and improve flow in the pipe rather than widen the pipe, and the best pipe size for our engines is 2.25 (I believe). Higher pressure scenarios such as turbos will benefit from bigger piping.

"When contemplating a modified exhaust system there are those who want the biggest diameter pipe that can be had. Their idea must be that fatter pipes are more effective at venting than narrower pipes. This sounds reasonable but it is not quite correct. Sure wider pipes have greater volume and higher flow capacity, but that is just half of the story. Capacity is one consideration but gas velocity is the other factor.

An experienced exhaust designer knows that the best exhaust is one that balances flow capacity with velocity. A given volume/time of gasses will travel faster through a 2" pipe than the same volume of gas passing through a 3" pipe. So when taken to its extremes we can see that a too narrow pipe will create backpressure (restrictions to positive flow) problems and a too wide pipe will cause a very slow flow with no backpressure."

The optimum is where the fastest velocity is achieved with the least constriction possible.

Why would you say 2.25 is the best exhaust size for us. Is not that the stock size.? I agree with some of what you say 3 inch is to big unless you are going FI. But I would think 2.5 would be a much better exhaust flow than our 2.5 stock system. the stock system is pretty strait and the only down falls are the huge resonator and the squish we have under the rear seats. Replacing from the cat back with a 2.5 inch system is a great idea. IMO.

 

Screw that catback, go with headers, gain more, way more.

 

"Screw that catback, go with headers, gain more, way more...cost."

The whole idea of this thread (from the originator) was to get sound, a little performance, a shiny look, at tiny cost (very tiny), last I checked. The man asked is it worth it? I and a few other people want to know too.

But spend a lot more & you'll get a lot more with headers that's for sure.

Now Maxinuff, that's enuff waiting for us this life time. Where are the sound clips man?

Prescence, thanks for your input regarding the catbacks. QuakQuota, thanks for forcing words that can be more easily read. J/K QwikKota

 

You gotta pay to play.

 

You aint neva lied!

 

Lots of speculation in this post.
Cattman already proved that a 2.5" split into two approx 2" mufflers was the best for performance.

 

I have no idea about the actual pipe size, I was just speculating.

Joshua

 

Here are the clips as promised. sorry for the wait, I've been doing the best with what I have. today is the first decent day we have had in a while.
