Plus dont plan on putting Test pipes on it because it will have a very very high Whistle howl noise that comes from the increased exhaust flow in the X pipe. This was the reason I switched to HKS.. But I did talk to ARK and they said they were designing a HFC that wouldnt make that noise and increase flow..


Good Luck!
