Hey Guys,
I was just wondering if any of you own Stillen HFCs. How are they. Do you like them or not. Im pretty sure im going to get Stillens. I have stock exhaust and i want it to be a louder with out getting a whole exhaust system. Are there any HFCs that are better then the Stillens?
Thanks for your help

Go with Fast Intentions HFC's, or Berks HCF's. I used to have the F.I. hfc's and loved them.
