I had open headers for a couple days and everything was fine. Yesterday I put on the ORY and catback, and now every time I go from a dead stop/turn I can hear a grinding noise. I used the horse shoe exhaust clamps rather than welding it. Could the noise be the bolts or something vibrating?

i had that problem. there is a small bracket under where your y pipe merges, if its there take it off. other things could be the driveshaft hitting the exhaust or hitting a heatshield. poly mounts will fix that. and unless you didnt tighten the bolts all the way they will not vibrate. my rumbler has those clamps and have not loosened a bit

As hit man said, check the driveshaft clearance as on my Borla one of the clamps has to be rotated or the bolts will contact the drive shaft all the time.

when I put on my pacesetter y it was vibrating against the hard lines underneath on the drivers side, I just bent them towards the floor a little bit and no more noise
