I am in the market to purchasing Headers and X-Pipe for my Vette. I am currently running a 12.2 with a Tune and Intake, and would like to bring it down to the 11s. My question is do you recommend me getting Headers and X-pipe, with or without the CAT's ? Will there be a difference in power and sound?
I would definitely recommend headers and x-pipe as your next mod. I think the difference between x-pipe with cats or without in hp gains would be minimum, so that would be a individual decision to make.
The only reason to get CATS would be because of State Laws... If your State laws dont require them then you can save yourself pocket of cash to put towards other mods.
I live in South Florida and plan to have the Pfadt Tri Y headers with mid X pipe installed. In my opinion these look to be the best performing and easiest to install in my driveway... I'm all about both.
I was going to get the CATS but since Florida laws dont mandate CATS.... I plan to put that 300+ towards a tune or even a new Cam.
