Tempting. Was planning on upgrading to a 3" or 3.5" exhaust and of course doing back to back dyno runs with my VQ30DEK to measure the gains, if any. Just as I did with the Cattman headers.
I know fitment will be spot on, even with the stock muffler. However will all the flanges be stainless or at least nickel plated on this 600 ~ 800 dollar catback? I don't want anymore rusty exhaust flange syndrome that seems to plague every exhaust part that is made for a Maxima.

We typically nickel-plate our 3/8" carbon plate flanges, but stainless steel is a poor choice for a flange material because it expands and contracts with heat much more than mild steel, and it can work the nuts/bolt loose over time. Stainless head flanges on header manifolds can actually pull the studs loose over time, which is a real bummer.

As me and my demented self actually tried to fit the stock muffler on this system, I found it would take a little work, since the 3" flange is quite large in comparison to the OEM A33 and the flange holes do not line up.
BUT, the with a little work, they would and the old flange is right where it should be WRT to the Cattman system and OEM rear piece(this is for the A33).

Due to the difference in flange sizes (between 3" and stock), I've been telling people that they're not really interchangeable, and what you've said about a bolt hole mismatch confirms that. However, its useful to know that the rear b-pipe and muffler flanges meet up where they're supposed to, that makes what you're doing possible.
Thanks for the information!

I'm in, do we know how much 30% is yet?

Awesome. Thanks for joining cardana24.
Now that we have 8, I'm sure Brian will let us know what 30% equates to, and the next step for all of us. If anyone else would like a 3" catback, please add your name to the list as well. The more the merrier.

YES!! We did it! Thanks to all for joining in, Im sure we will not be disappointed. 
Brian are we going to be using a nice 3" exhaust tip like we used for the 2.5 exhaust? Don't forget to take into account that the rear bumper of the 97's is a bit longer than the 95/96 max (Im sure you know what your doing). Just a reminder so the muffler tip sits a slight bit past the bumper on the 97/99's. The muffler tip for my 2.5 sits a bit passed my bumper now and its perfect.
On to the next step Brian. Please fill us in.

Your looking into getting the Cattman headers as well? Im not sure if the 3" exhasut that will soon be in production will bolt up to it. I have the Cattman headers now I believe they are 2 and 1/4", (someone correct me if Im wrong) in any event I'll be selling mine and going back to stock headers for the turbo.

IIRC, there is discussion about this on the 1st page of this thread.
Now, a 3" y-pipe would be fun.

Not sure what tip we'll use. Since the opening at the end of the muffler has to be a minimum of 3", the tip might need to be slightly larger, but that's based on fabrication details that I'll need to discuss with my exhaust partner. We don't do grapefruit shooters, so no worries about that.
My favorite is always the clean, single-walled stainless steel tip, slightly slant-cut, like we use on the 5th gen - not dual tips, of course, but a larger version with a single tip.
Keeping in mind this isn't our first rodeo with the 4th gen catback, we've never made two different mufflers, just a matter of averaging out the difference in length - one size fits all.

Quite a few turbo builds have incorporated our headers with excellent results, but that really depends on the approach the system designer takes and how radical it will be. They work great in an 8-9lb system (or up to 350-375whp), but in all honesty, I don't think that tubular headers are appropriate on big-turbo builds. You really have to use a cast iron product (ideally a plenum-style cast manifold like JWT designed for their Z turbo) to stand up to the incredible heat and stress of a high boost/big turbo system. Nobody's going to design a cast product for one or a few turbo systems, so that leaves the stock manifolds (after a honing, I assume).

The outlet of our header y-pipe is 2.5", and if a Cattman FastCat is involved, that opens up to 2.75" and the catback of course is 3.0". All fit perfectly (even with a stock cat) and may I point out that this is the perfect transition?

. Im assuming that the 1/4" difference between the Cat and exhaust wouldn't hurt power output of the turbo. I also heard about the headers and the possibility of them not be able to with stand the added heat and pressure, which is why Im going back to the stock headers. Good to hear you confirm this. Not sure what tip we'll use. Since the opening at the end of the muffler has to be a minimum of 3", the tip might need to be slightly larger, but that's based on fabrication details that I'll need to discuss with my exhaust partner.

Most turbo systems aren't intended to make over 350-375 whp, so the headers will work great (add power primarily at the top end), but if you're going to get crazier than that the stresses are too intense and the higher boost levels makes that flow less critical.

I heard from a member here that the Cattman headers need to be chopped up to make the custom pipes to weld/v band ( which ever method to connect the pipes) to it. He told me Im better off using the stock headers and selling the cattmans, also he said the bigger headers ( cattmans ) will cause turbo lag so stock headers were the way to go. Can anyone else confirm this?

Yes, Im not looking on making over 350 whp and I doubt I could with the Vq30 without blowing up the motor.

There are many different ways to configure a turbo build. We've sold several manifold pairs to builders who were going to leave them intact. In a couple of cases, the turbo designer even wanted to modify the y-pipe. It was going to be chopped and changed, but that builder figured he was farther ahead by modifying our y-pipe than building one from scratch.
Figure out who you want to do it, work out the design details, and let them determine what to do about manifolds.

OK, now things get serious! Initial response has been good, but now we start the "real" list that will determine if this project moves forward.
Introductory "early order" price for the first batch of Cattman 3" catbacks for the 95-99 Maxima will be $725/unit. A 30% non-refundable deposit of $220 will be required, but I won't charge any CCs until we have at least 8 orders in hand. So, no payments until we know we have the minimum # of orders.
I expect development to proceed quickly since there's a donor vehicle available and we're modifying an existing part rather than developing a new one, so I'll estimate 5 weeks between the fitment session and a finished product (perhaps a bit sooner).
We take orders by phone at 800.759.9920 and I'm usually available to answer any questions too. Our hours are 9-5 MST/PDT, M-F.
Place your orders ASAP and lets get this project rolling!

Reason I ask is that I want to have the muffler hidden as much as possible. I might spray paint my existing Remus muffler setup black. Cali may have bad smog laws but all aftermarket exhausts are illegal in Mass, regardless if they are below the DOT approved level for exhaust noise levels. It is the officer's choice to ticket you, no sound dB meter is needed. So most cops ticket younger people driving import cars or ticket if exhaust sounds like something the cop doesn't like. I am getting sick of cops seeing my car's shiny muffler and then tailing my car for a couple miles especially at night.

Will there be a different design for the '95~'96 vs the '97 ~ '99 in regards to the exhaust tip sitting flush with the bumper? I know the '97 ~ '99 are more popular so I am assuming the tip will sit flush with those bumpers and stick out a bit on the '95 ~ '96 bumpers. Id like a 3" exhaust tip as well keeping it low profile and classy, not some 5" chrome cannon tip.

I'm not a fan of grapefruit-shooters and I know you guys aren't either. Depending on how the muffler is actually constructed (it will be built in-house, not purchased) the tip will either be the same diameter as the tubing inside of the muffler (3") or slightly larger (3.5" at the outside).
Resonated? Oh yes, gotta be for all except perhaps turbo owners. Let's put it this way, if you DON'T want a resonator, let me know when you order. I'll knock $40 off the price, but that makes it a custom order because few will want it this way... I'll discuss with whomever wants it this way.
Tips... Seems like this came up already, but maybe I discussed in a PM. I realize there's a slight change in bumper "protrusion" between 96/97, but we've always taken a one-size-fits-all approach that's worked out pretty good. That said, we'll be eyeballing the design so that its the minimum length that makes sense on the 98 fitment car, and that will work fine on the 95/96.
BTW, when I'm measuring the tip relative to the muffler, I'm looking directly down (perpendicular to the ground) and measuring the tip against the edge of the bumper that sticks out the farthest (a few inches above the tip), not the opening in the rear valance.
I suppose its possible to paint the muffler, but it tends to come off. A customer asked recently about having another muffler we make ceramic coated in black or dark grey (everything but the tip) because he wanted to be as stealth as possible. There is a coater by our exhaust partners, and I'm looking into prices, so that could be a possibility as a custom option. I think it would be pretty cool.
Finally, I don't want seem like I'm picking on anybody, but I'll point out that all it takes is a couple guys who "aren't ready yet" and this project goes on hold. That's always the challenge. Not so hard to find a group of people who will say "me, me", but that can fall apart if a few drop out when it comes time to put up. That's why I won't take any deposits until I'm holding the minimum # (8) of paper orders.
