i'm having trouble with hanger closest to the b-pipe on the exhaust.;it wont fit correctly! do i need to have them bent or reweld into another spot? anyone else out there have this problem?

 

I'm getting fitment isssues too on my recently installed Greddy SP. What my speedshop suggested is to adjust it by shortening the CAT a bit. We're fixing it this weekend so I'll post some pics or more info soon after.

 

 

I would just like to know how in the hell do you shorten your cat??!!

 

if its just an inch or 2, we can cut and reweld the flange on each side...I actually have a test pipe that we will try and shorten to begin with and work from there...

 

Sorry to hear you're having problems. I put on a DC header, OBX stainless test pipe, and the SP. 0 issues when putting it on, everything went together better than the factory system. What engine are you having trouble fitting it with, mine was my ZC daily driver.
