I've got a 97 WS6 and I am running mac single cat headers, MAC off-road pipe, and eibach sportline springs. I was wondering if anyone has had any problems with the MAC orp rubbing over speed bumps etc..? My brother has a similar set-up but has no rubbing issues unless it's a big bump. Does anyone know how to fix this ie.(adjusting y-pipe, orp and cat-back)?
Also, I'm running a borla catback and it is slightly rubbing just above the rear axle(near the heat shield) and is making an annoying vibration, is there anything I can do? Should I just try adjusting each pipe from the ORP back to try and get clearence?

Thanks

 

i used to have a MAC single cat setup with an ORP and sportlines ..

the flange on the ORP rubs .. but no biggie .. then i got FLP longtubes and all problems went away
