Hey guys i was just wondering if a test pipe would make a difference in sound. Right now I have a Helix HFC. I WANT IT LOUDER THOUGH! Ant suggestions on the best test pipe that doesnt need a CEL fix? thanks guys

 

PM me if you need one, I can get you one on the cheap (I have an extra, never been installed, and I'll even give you my 2 non-foulers to fix the CEL problem).

let me know.
