I just installed my hks catback and i noticed some noise when i accelerate, is this something normal? Or Should I take it back to where i got it installed and have them adjust it.

 

What kind of noise.

 

It sounds like something is rubbing against the exhaust, you can only hear it when you accelerate. After that you cant hear anything. I was looking underneath and i'm not sure if the sway bar and the pipe rub against each other and might be the cause of this.

 

take a video

 

i'll post it up when i get a chance
