GTZ 2 1/4" Mandrel Catback SunPrairie, WI

2 1/4" Aluminized "catback" with mostly mandrel bends
This actually starts where the resonator ends so its not a true catback
Removed from my 90' GTZ. This is the setup I dynoed 237whp on. I have about 17xxx miles on it.
I replaced it with an Wicked-Iroc piece

Did you install the 3" kit on an NA Quad? I have his kit as well but thinking 3" is waaaaaay overkill at this point, considering I'm NA.

If it helps my 7.5 L v8 has 2.5 inch dual exhaust, about 3.75 L per side. My max rpm is only 5k and I have a mild cam in it. I've been told that 3" pipes would be overkill for my setup. lol
