HFC raspy noise

I currently have HFC and its making a lot of raspy noise when its cold. If I change to aftermarket exhaust system or just the cat back would it get rid of the raspy noise?

Putting on an aftermarket exhaust should smoothen out the sound since the piping will provide much better flow. When I put the JIC y-pipe on the Greddy, it really made it sound smoother.

i was also guessing our stock muffler was making the raspy noise even worse... Da Hashi and Gamedog heard it...

Yeah, it doesn't help if you have the infamous muffler rattle.

you will still hear little rasp sound even intalling the cat back exhaust but
it's not too noticable. you'll like it with combo/HFC & Cat back.
When we add JWT then we will rock & roll.
