Hopefully you can move the cats back to reduce pressure right after the turbo. I had FP create custom cats, 3.5" inlet/outlet, 4.25" core 200 cell metallic. Still lost a solid 40 whp vs. 3.5" test pipes.
If you can come up with a quiet exhaust that matches my custom cats + evoTT performance wise, then I'm ready to give it a shot. Good luck!

This causes about a 5-10 HP loss for the first several seconds after launching. (I'll post the Temperature Vs HP dynos.)
IMO the stock air box is the best all around air intake available for the Z. ...That is until the Motordyne Iso Thermal Intake comes out.

Any other modifications that we should know about?
What kind of gains can we see with the Iso Thermal Intake?

Meanwhile, does anybody know if/when MRC is open for business?
I can't get hold of anybody there.

As shown in the plots, air intake temperature has a very large effect on engine power.
This is why your car feels so much snappier on a cold day. It is also why air intakes should be completely sealed against induction of hot air from the engine compartment.

I don't know if it has been asked, but have you taken into account ground clearance for lowered cars? the placement of the 'cat' section on the Y pipe seems like it could hang down a little lower (not 'hang' but the size of the canister might stick out) than the frame. and that is a section I always rub.
