I've had my 18" res exhaust + HFC on my car for almost a week and a half now. I absolutely love the sound.
A nice deep smooth bass sound when running at low RPM. High gear on the freeway and you can almost get it to go silent with just your throttle control (no drone!). Give it some gas and it has a nice throaty growl to it. Really open her up and this thing just roars!
