I feel if you like the exhaust and it fits your budget buy it . Thumbs up to for modding your max!

 

I endorse this comment...

 

Oh and if anyone does post a VID of the sound, here is a VID of the GReddy sound for comparison...

You spend twice as much in this case and i will garantee you will get twice performance and twice attention. if you want your car to sound like a 93 honda civic, go and buy one of those.

 

Gee Farzin, how are you going to guarantee that man? The only guarantee is that you miss-spelled guarantee.

Why don't you just wait for the sound clips and more feedback before you dis maxinuff's system. Not everyone can afford to pay $750 for a catback system. If this system sounds better than stock, and half as good as greddy, and it does not fall apart in the next year or so, it may well be worth it for some members.

What on earth makes you think it's going to sound like a 93 Civic? Hell, on some of these expensive catback systems I see members spending even more money on things like sound deadeners, more friggin' pipes, and still have a tough time with droning.

Chill out and lets wait & see, before we start making rash assumptions.

 

Here's the Cattman exhaust thanks to coitaltie. I'll do my Cattman + Vibrant Resonator here in a few days once I got the extra resonator on...

Ive had an ebay ehaust and y pipe and it was fine. Although as stated its a matter of how long you keep the car. I dont keep cars very long usually and only had that car for about 2 years before I moved on to the max. Cant say how long it lasted but was happy with the sound and quality.

 

I personal like the sound of cattman exhaust the best but can't afford it! I think its pricey but a quality product. Their a smaller company and can't afford to give the discount as the other larger exhuast companies. Maybe once their name is on some of the nascars running the track the price will drop and I'll be able to afford it.

 

The Cattman is definitely a quality product. It was funny since it was loud in the cabin for me and didn't pass the wife test (fine for me though). So I ordered another resonator. I kept shopping around and tried to find a second resonator to weld on that would look as pretty as my exhaust. The Cattman exhaust is eye candy, thats for sure. Quality end to end.

 

I think the ebay knock off is a decent upgrade if you only plan to have your max for say a couple of years. But if your in it for the long run buy original...

 

I love the Cattman setup also but last I checked right up there in price (if not more) with the GReddy SP-II and this thread is about buying a GReddy knock-off catback system to save money...

 

Everyone remember that these area mandrel bends and stainless steel. to get this custom fabbed at a muffler shop (THAT CAN FIRST OF ALL DO THIS) would be at least $1000. The ebay muffler has to be better than the stock so whats all of the fuss.

 

I guess because it came from china,cheaper quality and is a knock off from a quality name competitor that did the r&d.

 

Has anyone ever tried some stock 350Z or G35 Coupe mufflers to see what the car would sound like? Its a bit too quiet stock for me but I like the ways those 2 cars sound for factory. I would think they could be found cheap from someone who removed theirs for an aftermarket system. Not for a power gain just sound change on a budget.

Nevermind! Looks like some oddball uni-muffler like the Camaro's etc had.

 

Dont think they would fit as they are huge compared to what we have now. Keep the stock system and but a y pipe instead.

 

Yeah, I edited my post. I looked at some 350Z aftermarket y-pipes, I guess you'd call that our B-pipe, to see if they could be adapted but they are almost as much as the Cattman B-pipe and don't include a resonator. Like I said in the Cattman thread I want to hear a stock muffler/Cattman B-pipe w-resonator setup. I think that is $400 or so.

 

Thanks for the support. i can definately tell you guys right now its not asloud as cherns system. But then again, ive never stood behind it when giving her hell. lol, always been begind the wheel. How on earth did a 93 civic even get brought into this? Last time I checked, Civics never came with a v-6, thus they cannot even be mentioned in the same sentence when talking about exhaust tones.

 

Just wanted to pop in and say I didnt't forget about this thread. The car is off the boat and doing great. I'm just waiting on internet to get set up at my place before I post up the after vid. I'm at the library right now On the way home from picking the car up I came acrossed a no limit zone on the Bahn and ran her up to 140. Man was it hairy.


***To whom it may conceren***

I was NOT racing when I hit 140.

 

Good to hear the car made it ok, and up 140?? Craziness.. LOL I still wating for the sound clip. I also removed my Factory resonator with I strait pipe by the car sounds the same?? I started a thread about it but it died after someone said there could be carbon biuld up in the muffers and deading the sound. How the hell to you check or clean that??

 

Change out your mufflers as there is no way to clean your mufflers efficiently. Still hard to believe that it sounds the same.

 

can't we all just get along?
I think he has a point for the price of the cattman or greddy you could buy 2 or 3 of these setups. If the exhaust is crap its crap, but if it's actually good he will be laughin at all you bashers. If it's crap you could always have the welds re-done and change out the mufflers to bettar ones and still be under the major competitors pricI give them props for tryin this. With 2.5in piping we will luse torque but nothing worth crying over, and what we luse we will gain in hp, are cars have enough torque as it is

 

I dont know about that. I have the greddy and the TQ loss is evident. You will only see that HP in higher rpms anyway. I personally prefer the missed low end TQ. Unless you get some sort of tuning after the exhaust is added to correct it.

 

IMO, tuning is not necessary, nor will be noticed on a dyno or otherwise after such a minor modification, unless you were dropping the car back altogether (open manifolds)

 

What about if you want the low end back you would have to tune then right??

 

Nope, the AFR theory does not hold true in this case since the effect is very minimal. Also, AFR isn't going to make much difference on the low end since it would probably be at part throttle, and be maintaining a 14.7:1 ratio.

Like I also said though, if you removed the entire catback, then that would affect it (performance & power delivery) more, but not in much terms of AFR and 'low' end, but more along the lines of backpressure. Also that topic has been horrifically abused here and in this case, should not have even been brought up, but it was to make a point with respect to AFR.

 

So how is the back pressure corrected?? Smaller diameter piping had been talked about but nothing solid. 2.5in to 2.25in maybe.

 

I never said it was corrected, nor is it even remotley changed in the case of changing from OEM to any other cat back.

 

But I noticed a difference in performance from before I had my greddy to after. I initially had just the fujita. But my dynoed showed an AFR of 14 then another AFR of 13 Not the best dyno but it's the only one I got before my TS flash

 

Unless you have definitive data, we could be here all night, but until there are numbers, even if they are just airflow numbers and not actual dyno numbers, we should stop here.

It’s just like me and my MAF mod, how do you prove that there is a horrid amount of part throttle low end torque and throttle response?

One test I thought of was to log when my accelerated was pressed and when the vehicle began moving, but that takes a lot of time, and well, I know it worked for me. But I still may do the test.

 

I the only dyno I got with showed AFR but I'm not sure that was correct. They didnt start graphing til 5400rpm. What I would have to do is take out my TS ECU and put my stock ECU back in and dyno at the same place I have gotten my 3 dyno's. The very first dyno is inconclusive.

Did the MAF mod feel different to you in the low end??

 

The MAF mod did worlds of wonder for the low end. I read another members posts where he had done it and said the same thing. I did the mod, and everything I wanted to say about it had already been said by him.

 

Hello! I would have to confirm that the ebay Cat-back Exhaust is superb, right when I was going to fork out 6 to 7 hunderd dollars for the exhuast set-up. A friend of mine that has a 2005 Maxima, said don't spend that much. For the longest he told me he had the Greddy Exhaust on his ride. Because when-ever saw it, along with hearing it perform, made me want the Exhaust set-up really bad. The Sound, Performance, Quailty, is top notch, the only difference is that you don't have to bad $500.00 extra for the Greddy logo. We even took it to reputable Muffler Shop, an they even confirmed that it was a good quality system. So I 've had mine for 2 months now, excellent product for any one that is considering this unit. Couple sound clips below of the original cat mufflers, and the new JDM styles. They will be removed as well for my custom 350/g35 exhaust set up. One muffler running sideways in the rear, with two active duals. I know your saying Yeah! How are you going to perform that task, Very easy! Where removing either half or the entire spare wheel section. There's more info on the other 6thgenmaxima.org, I'll post the link shortly.

I dont really know what to say. Without the graphs there is no proof just butt dyno. Still thinking about that MAF mod though, if I ever decide to go back to my stock airbox.

Don't buy **** and your car will thank you. Watch the video. Think about it. They buy a quality product not only you can rely on but your car can too. I'm not saying to go with name brands necessarily or expensive models but to do your research to effectively allow you to buy a quality product.


Wow that video is like 1.5yrs old. I need some new videos and pics of my mods. It's all chern's fault I swear!
Btw chern smells. Love the turbo install tho!

 

Wow that was hard to read. I wouldn't consider hacking up the unibody 'easy' and not many would consider altering that. Hopefully you are at least welding back in plate to box in the remaining section. That area of the car is still needed for structural rigidity. And are you going to have a custom made half-round spare wheel/tire fabricated for you? That's what I'd go with.

QuikKota! The information submitted previously, was corrected, so that it wouldn't be difficult, No! Hard! To comphrend. But for some reason, you seem to have fiqured it out. Now! On to some other points, that you tried to make earlier. Structural rigidity? A Reputable Fabricator that has performed all the work, on several of my vehicles, including friends of mine. Stated this wasn't a difficult project @ all, So! His word definitely holds more water then yours, No offense! Especially when it pertains to this particular situation. Also, where did you get the interpretation, Hacking up! The underbody has been inspected, for this up & coming project, an will be professionally welded, so that the Structural Integrity, Not!!!! Rigidity!! Isn't jeopardize. Where not going to perform anything that will interrupt the Frame stability of the Maxima. There's actually several option, that where given to me. An, I really prefer the one, where the spare wheel section is fabricated, to move it upward. So, that a muffler could lay directly under. Everyone's opinion is definitely taking into consideration, so don't think, you would offend me @ all. I really do appreciate your input, an like they say, "The proof is in the pudding"

Why not with an aftermarket intake?

 

It would involve cutting the fujita which I really dont want to do unless I can get one cheap off someone on these boards. Still got some other mods to do though. Did you get the pm I sent??

 

Ah yes, I remember now.
