I'm going to buy this exhaust this week along with some HFCs. First, where is the bottleneck with this exhaust system and what should I consider replacing for the fix? Second, what are some recommended HFC's that will work good with this catback exhaust system? I need to keep the modding carb legal, I'm not a pro at switching in and out parts and will be moving back to Southern Cali this year.

Thanks!

 

You mean HFCs? Berk and Stillen are good choices and are the most common. Just to give you a heads up, they are illegal in Cali (just like every other good thing).

 

Yea I have no idea why I have HFK in my head.. I've read that the Kinetix HFC are 50-state legal, are they the only ones?
