I very much agree. The HFCs won't disappoint you at all. They add a nice deep tone to any stock exhaust or aftermarket, for that matter.... as well as HP. My Stillen's been treating me good, but I'm ready for an upgrade to the FI setup
I can't mention this enough haha. I won't do TP just for the fact of raspiness..they add alot more than the HFcs
