I have plans to finally purchase my Fujitsubo exhaust following the holidays. I am also getting the Fuji Y-Pipe... Now, Do I go with Crawford High flo cats or test pipes? I am moving to Florida in June (Navy) and smog is not an issue there from what I have heard. Are there benefits to going with Test Pipes, or do I just replace my stock cats with the Crawford high flo cats?

What are the differences in gains/losses going with test pipes vice cats? Thanks for helping me plan out my future exhaust setup. Oh... I guess it might be important to know that I plan to put on some Crawford Headers in the future, and maybe go with a vortec SC. I currently have a drop-in K&N with Z-tube.

 

go with the Crawford Cats and the JIC Y pipe which is straigher than the Fuji.
