Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

u155282 · 03-25-2010, 09:29 AM

I love the sound of the LTHs and the performance bump is great, but what if I wanted to keep it smog legal and a little quieter than straight pipes? I know it be expensive and it would negate some of the gains from the LTHs, but what about cutting out some space and welding in a pair of HFCs? Totally not worth it? Would you see any gains from having LTHs in that case? Has anybody else thought about this?

I still don't have a car, just curious/dreaming. I'm that guy - sorry.

They wouldn't be LTHs anymore if you did that. They'd be regular short headers.
