I have finally identified my headers that came on my car as tpis. (no tag or stamping that I could find)
I was just trying to find a catless mid or x-pipe to go from the headers to the factory Ti mufflers. I can't figure out if they share the same separation distance as stock or another header company.
Random Technology makes a specific midpipe for the TPIS (or did).
The ones I have seen advertised had the high-flow cats, but they may be available without cats also. RT is pretty expensive though.
That being said, have you ever owned a vette without cats? Not a big thrill for soooo many reasons.
Thanks for the quick reply and info. I already have te factory cats gutted and plan on doing the muffler mod. I agree that no cats is not for everyone.
