I also have pop charger and motordyne 5/16

sounds really good. really good.

 

Sounds great. How much louder is the exhaust after the hfc's? Any vids of how it sounds inside? I want to get an exhaust, but cops around my area have been giving tickets for loud exhausts like crazy.

 

it sounds deeper til about 5 and when i get to high rpms it sounds about the same. it sounds about the same but deeper and amplfied...ill post some vids of it inside soon

 

Sounds pretty good. Im still on the fence on getting HFC's.
