Cattman + Greddy = hp?

[lightsout]

Honestly, I must be the only one on here that has the Stillen exhaust... ...i wanna replace the exhaust manifolds with Cattman Headers, Stillens Race Pipes or Cattman Race Pipes, and then purchase a Greddy muffler and weld it in w/ stainless piping and welds. i want to run 3" pipes through-and-through if that's possible.

Another option would be to build the entire thing w/ custom stainless piping, and making it dual throughout w/a Y-pipe and 3 High Flow cats to keep her clean...if i do the dual, i wanna install a flame kit!! The on ly way I could fit True Dual Exhaust is if i cut out the spare tire space in the trunk and made it flat...it would also call for some modifications to my stillen rear lip.

some people would think i'm crazy... ...they're right!!

i'm hoping to get at least a 20hp gain outta that...do you think i'll get more?I also have the Stillen 6x5 Short Ram filter installed too!!

I hope this doesn't seem like shameless self-promotion, but these are good questions and no one has answered...

Why 3" tubing? Unless you're doing a large s/c or turbo installation there's no point. Going 3" forces you to go custom which, if done locally in stainless steel (if you can get anyone local to work with stainless steel tubing and cut bends) will tend to be pricey and very possibly not well executed. Go with a complete 2.5" catback system and avoid the headaches you're lining yourself up for; and, if performance is your primary objective, skip the dual exhaust - it may look good, but that setup will cost you power.

You can't beat the fit, performance and seamless integration of a complete Cattman exhaust system - header/y-pipe set, FastCat and catback.

i'm not running a turbo...so forget the 3"!!

i love the sound of the Greddy Evo2 with the cattman racepipes.

i spent hours last night finding video clips for Maxima exhaust on youtube.

i haven't made a final decision....OOO...what about a cherry bomb!?! ...JK JK JK JK....LMAO!!

[Cattman]

Its key to remember that there's never been a exhaust soundclip recorded and played back that sounded like the actual vehicle. There are three components to exhaust sound - volume, tone and pitch - and the only one that comes through a soundclip (and even then, not well) is pitch.

Thank you for dropping some knowledge Brian, it's always welcome.

You guys should consider megan cat-back which looks just like cattman but half the price. It's all stainless steel thru out and the welds are done right. My friend just got one for his 5gen and it looks and sound nice too. There was no problems with fitment also and direct bolt on.

Sorry, but I can't let that slide. The Megan is a cheap Asian-made knock-off that uses materials and components that are inferior to the US-made Cattman catback. Put the two together and you'll definitely see that the Megan is not "just like" the Cattman. Not even close.

You get what you pay for.

I agree Cattman!!...you get what you pay for, that's why i try to do all my work myself, and purchase from Manufacturers that have outstanding reps. I want the custom look of dual on my generation of maxima...i haven't seen one yet. So i'm thinking the Cattman Headers and Race pipe...then i'll get a custom pipe bent from the flange directly in fron of the rear axle, and pipe in two Greddy Evo2's...that should have a deep sound.

don't forget the fun behind the flame thrower!! i'm not rice, i swear!!

I was one of the people that helped install Fezzik's Cattman headers and coil overs on his 02. I can tell you personally that the fitment was perfect, and the quality top notch. Even when we had questions, he took the call personally and helped us out. You're not going to find that kind of service from a knock-off manufacturer.

Hey I was looking (probably not in the right spot) and couldn't find details on the headers for the 5.5 gen. Can anyone point me in the right direction?

[Cattman]

geez, don't know how I was boneheaded enough to post something twice...

[Cattman]

If you know a little bit about Cattman Performance, you might be aware that although we have a solid reputation for parts and customer service, our marketing and website capabilities come up way short, so I apologize for the lack of accessible information on our parts (particularly some of the more recent ones). [I'm still vowing this will change, and no, we've got a good web developer, the problem is they have a bad client.]



I've attached a picture of the header/y-pipe system we sell for the 1995-2003 Maxima (and 95-04 I30/I35). Its probably inappropriate for me to do a sell-job in this subforum, so I'll just say that this is a near-equal-length design (manifolds and downpipe) made from mandrel bent T304 s/s, TIG-welded, all US-made materials, with all US labor. It makes 18-22whp on a VQ30DE and 22-25whp on the VQ35DE. We have several units in stock right now.

For additional information, feel free to give us a call at 800.759.9920, open 9-5 MST, M-F.

It sounds like you're determined to have a good time with your car, and I think that's great! Obviously the dual exhaust system will require some ingenuity on your part, but I hope everything comes out the way you want it - including the FLAMES!! You've got to bring back pictures once its done.

If you go all-custom with your catback, you might want to begin with one of our 22" resonators. Its the one we have custom-made for our catbacks, and we sell them seperately for welding into custom exhaust systems. All-stainless through and through (even the sound-deadening materials), this unit really works great and could easily be integrated with your custom system.

Price is very reasonable, and we always have them in stock. Give us a call at 520.575.6195 or 8010.759.9920, open 9-5MST, M-F, if you'd like to know more.

is the resonator something i can buy online?...is it legal to not have a resonator? what are the benefits of a resonator, concerning sound?!!

We take orders by phone, but since we don't have sponsor status yet its better that we go offline with any discussion about buying/selling parts. Look for an email.

Its illegal for a car to be too loud in most places, but how that's done (some combination of resonator, muffler, baffles, etc.) is up to you. Most small sport mufflers will be illegally loud, in most places (illegal noise limits vary from town to town), if there isn't some kind of resonator in the system too. The mufflers Greddy uses (as well as the ones we use) would be pretty loud without a resonator.

The primary function of the resonator is to take down the noise level significantly before the exhaust hits the muffler. That way the muffler doesn't have to be as large or include power-robbing baffles, etc, and the system can be less restrictive overall. In addition to reducing volume, a good resonator "shapes" the sound, creating a rich tone instead of a harsh, raspy sound that can come from muffler-only systems.

A resonator's ability to reduce sound is fairly proportionate to its length. The 22" resonator we use now is noticeably quieter than the 18" we used before, but that was a lot quieter than the 12-14" units you typically see in catback systems. Avoid resonators that 1) aren't stainless steel, 2) have little louvers bent up from each hole in the inner tube (should be smooth), or 3) have cheap fibreglass soundproofing material that will break down in a year or two.

take the advice from brian.

i'll be completely honest, i went through 4 'custom' setups and liked them all. once i went with a complete bolt on setup, it was over. i was in love. there is no comparison regardless. duals are nice, but its nothing but show. with intake, headers, and a bolt on exhaust, it should sound pretty beefy. i had lots of people ask whether or not my maxima was a V8. of course, we all know the answer to that

[lightsout]

thanks so much Brian and all...i'm going to be seeing some money soon when i sell my Custom F150(b/c i'm getting married)...and want to put some of the $ towards a new exhaust setup!! i'll be calling you Brian!!!

[Fezzik]

I figure i'd chime in here. If you want quality parts and someone who stand 100 percent behind their product go with Cattman. Like maxhopper said in an earlier post, i had some tough questions for him and he took it on himself to get me into contact with other people who had the solution.
