I am about to start doing some minor mods to my 02 max and after I put on an intake i am going to do the exhaust work but don't want a loud raspy one.....almost want it to be a sleeper eventually....would just a high-flow cat give the same gains as a full exhaust or almost the same? If not what kind of exhaust should I look in to getting?

 

Since there's about 4-8 threads ON THE FIRST PAGE OF THIS FORUM about exhausts including a ton of information, as well as a HUGE amount of info in the stickies, FAQ, etc, all you are getting here is

SEARCH

 

The use of terms together such as "sleeper" and "exhaust" for any vehicle immediately becomes a contradiction.

Best you might do is a 2.5" catback with a g35 axle back muffler. Said to be quite. However, the new Catman catback with larger resonator should be significantly quiter and net the most gains as well. His 3" is notes as quiter than any 2.5" system (except one with the g35 axle back of course).

Regarding the question about the catalytic converter..... By itself in a stock or aftermarket system, you are not going to see big power gains or tone changes.

 

cmon now. All stock exhaust with only a high flow cat will NEVER flow as good as a full aftermarket exhaust. No where near it.

Depends what you trying to do with the car. Cattman 3" cattback is a pretty quiet piece even quieter than any aftermarket 2.5" I've heard on a maxima. Even the 350z guys be like "What kind of exhaust is that?" People ask me ALL the time. I have full headers, fastcat and 3" exhaust from cattman. If you trying to make it a FAST car then headers and full 3" exhaust would be good. When you get a TUNE, which you should do, it gets even quieter.....until you get on that bad boy.

Do some research on here because people have all kinds of exhausts on here, BUT the most popular and favorite would be the cattman 3" system.

 

Thank you ranmas and chris for the advice...Tunermax sorry for being new to something and not fully understanding the stickies, way to help someone out there though pal...

 

would you guys suggest 04-06 Maxima JDM N1 Stainless Cat Catback Exhaust Muffler System Kit + Silencer?

NP dude.

Google.
Search bar at the top of the forum.
Search-this forum tool at the top right of each forum section.
Simply looking at the recent posts on page 1 and seeing a crap pile of exhaust threads, maybe clicking on them and try reading them.
Bolded threads at the very top of the forum section that say FAQ, HOW TO, I'M NEW AND HAVE A QUESTION THREAD (where you should have posted if you were too lazy to search)

I'm all for people posting and asking questions just to maintain the social aspect of learning about cars, etc. That is healthy, and actually serves as a nice refresher for content and new products.

If there wasn't a half dozen or more exhaust threads posted before yours, you wouldn't have got that from me.

Anyways, Did my post lead you to actually look around and search? Did you learn stuff?

 

On a 5/5.5 gen Maxima. Nah, too many installation issues.

 

I got reasonable gains from my setup and its not that drastic. Has a note very similar to a stock G35, maybe a couple notes lower. The most restrictive parts of your exhaust are the midpipes and the precats. Precats will stir up a bit of controversy as studies have shown that they arent all that restrictive. At least the bank 2 isnt.

If you want quiet or close to quiet, keep your stock muffler ON. Replace the pipes before the stock muffler with free flowing ones.

 

Considering all the Nissan pre cat issues , replacing/deleting them seems to be part of preventative maintenance now lmfao.

 

Im about to jump on a y pipe...lol. I just replaced my bank 2 pain in the *** precat with a nice new Walker one less than 5k miles ago. If i get the ypipe i'll have an exhaust good for another 150k miles.

 

Yes Tunermax, your post has led me to do research (which i had done via google, but didn't know how credible it was). I will become familiar with this website, thanks...Thanks to everyone else who has posted in here as well and given advice on my question.

 

Stock cat back can put down a lot of power, so unless you want more than 250fwhp, then stock is good enough, as the stock unit can support this number.

Seen it plenty of times.

 

"Can" support.....but holy cow! Like allowing a small child play with a rubber ball - can you say 'choking hazard!?' LOL!!

 

SR20DEN, 6Spd_Hayes both put down about 247 - 249 with the stock airbox (ported) and stock catback. They're both 6MT's. I put down 242 with the stock catback and an AT.

 

But for quicker, easier power than getting into BBMAF, TB, intake, header, etc, etc, the cattback is a nice quick power adder, would you not agree?

If going for big power it can be last on the list, for a simple bolt on power adder though, it's certainly big on the list, no?

Just cause it can flow x amount, doesn't mean increasing it's potential won't increase the engines output.

 

Clearly I'm not argueing with you, simply posing the question: But why would you want to?

 

I don't know ... I've always wanted my car quiet, and that's why I decided to get the cat-back late in the game.

Considering the price of a cat-back, I'd rather spend it somewhere else.

 

I think the even more money saving thing to do is just replace that crunched up B pipe with whatever the heck you can do.

That and getting rid of precats. I used to be against it a bit but man have I been turned. Those things are failing/clogging all over the place. Get rid of them!!!!!

The G35 forum is starting to see posts of loss of power/bogging at higher speeds/rpm and I've nailed 2 of them to precat failures already. The Nissan Precat issues continue. Shyt's everywhere it seems.

 

Yeah, I had a Cattman B-once upon a time.

Pre-cats are for poop, and need to be gotten rid of especially when the benefit is win win, longevity and performance.

 

what's cheapest way to fix precat issue without having to ship items from the US?

 

Punch them out. I suppose that could be considered a "fix".

 

You know technically....a punched out stock y pipe is really the only way to get an equal length y pipe anymore. Ive actually thought about this before. You could buy one instead of a warpspeed....plug the bung and reweld a bung up in the warpspeeds location. Have equal length y.

 

you wouldn't even need to do that...just throw antifoulers on the rear sensor locations if you really wanted to...

 

I'm gonna have antifoulers, on all of the sensors after I'm done. LOL...

 

All of these exhaust threads start the same. "Do a search, bla bla bla newb!" Then you all start bickering back and forth about what is the best way to go, or the best setup. B-pipe, no y-pipe, headers then don't need y-pipe, but Cattman sells them separate, Megan vs. SR-S catbacks...AGH!!!

Ever wonder why people keep posting questions? I never did personally but I will tell you I spent hours reading through numerous threads about exhausts and 90% of all of them are bickering back and forth. I know we all have opinions but c'mon people!

This is why I suggested a "definitive" exhaust thread with component combinations, sound clips, and some dynos. But, difficult task and no one wants to do it. Can't say I blame them, I don't either.

 

OBX vs Cattman Headers...

 

Cattman if you can get it.

 

Cattman, if you want to spend too much.

 

From the mass amounts of confussion I'm reading my understanding is that Cattman sells headers without the y-pipe (y-pipe eliminates pre cats). With the OBX it's all one piece. But that's from reading on here, not the Cattman site... so I'm probably wrong or mixing up info.

Personally I'm gutting the precats when install my SR-S catback. I'll look into headers after I invest in a TrasGo kit and a SAFC.

 

Do SAFC last...its tempting not to do so...ive been fighting the same urge. But get your exhaust EXACTLY the way you want it before the SAFC. Headers will change A/F by a great deal. At least they did on my IS300..

 

The reason its so confusing IS all the threads like that recent one where dude thought the y pipe was a separate piece, he didn't even have a maxima either...

The thread I made is a good crash course and there's other threads linked within that thread.

If you want accurate info you need to see those more definitive threads, not the weekly random postings that go on.

 

but really it is a small company selling to a fairly small community so to develop what they do and make a profit it has to be the price it is. Pay to play. Hell I have a vq30 so the last thing I want to do is make my exhaust louder

 

My Cattman stainless y was 350 bucks...which is only 50 bucks or so more than the stainless version of warpspeed's y pipe...with spot on fitment.

Worth every penny

 

I think I paid $250 for my Warpspeed Y pipe, and the fitment was also perfect, and it sounds great.

 

Cat back Exhaust is all noise if you don't have Intake (a REAL one) /Headers / Tuning. Once you have those, then a cat-back is justifiable.

But you all know that since you've researched.

 

Why not pull this: http://forums.maxima.org/6886993-post3.html out of 5th Gen General Mods, add to it, and sticky separately? I think it might curve the numerous exhaust threads that keep popping up.

So if my axle back piping cracked and the muffler was eaten by a Rust Goblin it is NOT justifiable for me to put the catback on the top of my list when it comes to the exhaust? I get what your saying but I'd rather have useless noise than the annoying sound of an exhaust leak. Any I'm not throwing money on an OEM axle back if I going to end up with a catback system down the road anyway.

Everyone's situation is different, just like everyone's preference and opinion.

 

I'd get a stock axle back. I'll sell you mine. 60$ shipped.
