I currently have high flow cats. and in the market for some test pipes. Did some research and iv been looking at z1's test pipes. The thing is im not trying to spend $450 for some SZ pipes i know there quality but for some bent metal little on the pricey side.

Z1's are 2.4" vs. 2.5 is" would that little bit of down size really matter? Im almost down with the clutch & flywheel install and putting everything back together next week so i figured why not since i just got rid of those horid precats and got some SZ spits. Just a thought your feed back is much appreciated.

I'm assuming you are talking about a TT?

Going from high flow cats to test pipes probably won't be much difference maybe 10HP? What other mods do you have? Are you looking to gain HP and not sure what's the best bang for buck at this point?

Basically everything you can imagine except dual intake and aftermarket turbo's. Just trying to squezze every little bit of power i can. I kinda figured from high flow to test pipes wont be a big enough difference to switch but for a 150 bucks why not.
