I have a 2010 sedan with the stillen catback and i looking for either test pipes or hfc. I need to know which has less rasp and good gain wise

Fast Intentions HFC's have zero rasp and gains all the way throughout the RPM band. I'm selling mine with just under 2000 miles on them, so PM me if you want. I'll give them to ya for way less than they cost. I took them off because it was a bit too loud for my taste, but I noticed a decrease in power right away. Even in the lower revs, they add power.

Wait... Nevermind... I forgot about the part where you have a sedan and I have a coupe. They're gonna be different. Nonetheless, you can't go wrong with either Fast Intentions or Berk.

Yea but hfc and tp are the same for coupes and sedans

Soliditude

My bad, lol. I've sent you the PM.

yea with the stock video there you can hear the difference. The car with HFc's sounds more like the coupe.
