hey.. i swapped catbacks with one of the iclubbers and now i have this vibration at only certain speeds.. noticed it on the freeway.. what could it be? exhaust leak? loose bolts? or hitting something?.... help would be appreciated.. btw i have a 02 wrx with turboback.. thanks.

 

If you haven't already found the problem, take a look at ur rear diff and ur rear sway bar, if the pipe is really close to either of those it could be hitting them. Other than that, leaks shouldn't cause vibrations, and loose bolts would be rattling so you should be able to hear them from outside the car with it idling. Good luck.

 

i have the same problem, but mine was hitting on my car. if you can jack the car up and jiggle the exhaust around you can see where your hitting IF you are. then from there use a cushion of some sort. I used a glob of double sided tape at both my locations. not the best fix but it deff helped out.

 

I'm sure longer exhaust hanger will fix that issue, I'm on the same boat as you, lol

 

That pipe gets to be about 600 degrees, that tape won't last...

 

Really? Mines been on for 6 months through track days and summer. Seems good to me lol. Want pics?
