Your opinion?

Looking to take off the OEM cats and put those aside for a long while haha being the most restrictive part of a 370z exhaust system. Looking for test pipes or HFC's

Being in CA test pipes are illegal but looking into them to have them for track and things like that for added whp.

I have the Fast Intentions 18" Resonated 3" exhaust system


3 questions I have that would like an answer to:

1. type of pipe (resonated/non-res test pipes or HFC's)
2. Brand name
3. Does it bolt onto the FI exhaust system?
4. opinion on the sound/noise gain and whp gain


Any and all opinions are appreciated
