3" Cattman catback exhaust for 00-03 Max - interested?
I've been talking to Brian Catts, of Cattman Performance, about the possibility of getting a 3" catback exhaust made for my car.
He is considering the idea, but would like to see what kind of interest there would be.
The cost is undecided as of right now, but it will be a little bit more than the cost of the current 2.5" catback exhaust.
This is a definite must for any Super/Turbo charged car - I'm not sure that NA cars would benefit.
So vote the poll and let's see what kind of interest there is....

There is no such thing as good backpressure.

correct, however it does reduce VELOCITY damaging power output.
Only a FI max would benefit from a 3" exhaust.

So we'll say that the 3" catback is for FI Maximas - I editted my first post....
How many FI Maxima owners would be interested in the 3" catback?

HNDA ETR, your turbo charged right? I think that you will see the best gains, but us NA guys will probably lose so much lowend torque, and only gain a little at the top. I was watching one of those car build shows (Horse power television I think) and they used 2.5" exhaust on a 512 ci crate motor. Maybe if I get supercharged I'd be down for the 3", but for now I think that 3" is a little on the big side for the way my car is tuned.

A 3" exhaust on our N/A's would definately be a bad idea. It would be loud and prolly sound like $hit. The reduction in exhaust velocity would kill low-end power and only be marginally beneficial right at the end of the powerband (which is stupid).
For turbocharged applications the 3" piping would be great.
I think you would see a lot more interest on this poll if you posted in the FI forum. I don't think you will find a lot of N/A interest unless they want to make their car slower.

i would love to have resonators and the lowest noise muffler possible. i would really like to have the performance gain and lose some of the noise associated with most catbacks.
would a 3" y-pipe be available? If so, could there be a WBO2 bung and EGT bung that can be plugged up if not used?

Try PM'ing him and asking about it.
I would be interested. Price dependent.
His 2.5" catback is about $600 right? A little much if you ask me. So I would imagine the 3" would be at least $700...at least, probably more like $800. I am not cheap by any means and have spent pleanty of money on quality parts, but his exhaust is over priced. Quaility, but over priced.

Sleeper96 gained 12 horsepower by putting an electric cut out after the cat and could deffinently tell a difference in his bum. A 3" on a N/A car would not hurt enough on the low end to tell a differnce. $800, forget that!!!! Go to summit racing get a flowmaster tail pipe kit for $65 and 2 mandral 90 degree bends fo $10 each then pay maxi muffler to weld it together with you favorit muffler, and wala, 3" cat back for $200.

have you ever heard the cattman catback? there's no way you'll get an exhaust to sound as good without having it custom built.. you guys seem to forget the quality and customer service that goes into the cattman catback (and all cattman products)... 100% stainless steel, all mandrel bent angles, giant resonator that retains the 2.5" inner diameter (means no/little performance loss) and the best sounding exhaust I've heard/experienced. Now, have your muffler place build the catback for you out of 100% stainless will all mandrel bends (cuz 2 90's aint all there is to the exhaust) and then pay for the labor on top of the parts, and I'm sure you're gonna be WAY over the $200....Anyways, like I said, Brian says that yes, the 3" setup will be, and I quote, "a LITTLE bit" more than the 2.5" setup... $200 over the cost of the 2.5" doesn't sound like "a little bit" to me....
Don't forget too, the Brian almost always has a group buy for his new products and gives a good discount... Also, on top of the group buy discount, if you spend a certain dollar amount when buying from him, he offers additional discounts - when asked for. Remember the group buys (multiple times, IIRC) for his headers? The group buy for the Energy Suspension bushings? etc...
Also, don't forget, we're talking about the FULL catback system - from the catalytic converter to the muffler tip... You can buy just the muffler section by itself - goes for $350 just for the muffler section.... add "a little bit" to that, and you're way under the 700-800 bucks people are predicting - as long as you don't need the full catback.
Remember, cheaper doesn't always mean better.
I wish Brian was paying me to hock his stuff, but he's not (hint hint, Brian!
) I just have always been impressed not only with the quality of his products, but the quality of his customer service. I've met him in person and he's a genuinely nice guy.

Things have been crazy busy and I hadn't looked in on this since thread since the beginning - sorry guys.
I always figured that the clearance might be too tight for a 3" production pipe, but the company that makes our catbacks thinks it can be done without rattling all over the place, so I figured what the heck, let's give it a try.
I asked HNDA ETR to rate the demand on these before we went forward (thanks mate, good on you) and I'm impressed with the interest, so I feel good about the next step, doing a "feasibility demonstration" by making up a prototype. We'll see how it fits and what kind of power it makes.
No way to estimate our cost or your price at this stage, but it shouldn't be a whole lot more than the catback we sell now - a lot of it comes down to how much more a 20' stick of 3" stainless tubing is over a 2.5" stick. I don't expect it to cost $800.
One thing I'll note is that I don't expect the mid-pipe and muffler to be interchangeable with the stock pieces like our 2.5" catback is - the 3" flanges will be too large to bolt up to the stock flanges. We do plan to produce a 3" version of our Cattman FastCat to go with this.
BTW, I agree that a 3" catback is limited to FI Maximas, with the exception of the sort of monster-built n/a engines that generally don't exist yet, and anyone running a significant shot of nitrous.
Stay tuned, we'll get to work on this.

Hey Brian, did you get my emails?
edit: another thought... would it be possible to have your 3" cat with a 2.5" flange on one end and the 3" flange on the other? then it could bolt up... just a though...

Brian, you could always make us a 3" y-pipe while you're at it. (Hint, hint)

sorry to bring up an old thread...but how much n/a buildup do u have to do, in order to require a 3 inch exhaust? I plan to build a vq35 with cams, high flow intake manifold, arp rod bolts, rev limiter at 7500...will a 2.5 inch exhaust be enough for this setup? or will a 3 inch be recommended? I always had the idea that vq35s are BIG displacement engines so they require big piping...i mean my friend with a 2.0l turbo wrx runs a 4 inch turboXS downpipe and full 3 inch piping....works great for him..and hes only a 4 cylinder with 2.0 displacement...
I can vouch for cattman products....my car currently has cattman headers and cattman catback...couldn't be happier about my setup...the gains are HUGE for a vq35....and the sound is to DIE FOR....you can hear the cylinders individually firing with these headers on....people compliment me all the time....
