H pipe fitment

Installed cat backs and an OR h pipe and my h pipe is hitting on my transmission crossmember on the left hand side is there anyway to bring it down? I loosened it up but cant pull it down, it only hits under heavy throttle or over bumps

What type of hangers do you have?

The h pipe has the bolt on hangers using rubber mounts, and the cat back is using rubber mounts as well

Also it's like a 1/8 inch away from the tranny crossmember would it hurt to put a peice of high temp rubber to act as a bumper?

Using rubber could lead to a fire if the pipe got pushed up against it long enough. I wouldn't do that.

Can you extend the hangers or maybe loosen them and see if there is any slack in the mounting holes?

I could possibly dremel the holes into a longated oval shape if there is enough meat to work with so to speak

Check Ur motor mounts, I had an issue with a bbk h-pipe fitment similar to urs but mine was at the front of the passenger side pipe by the k-member. I just left everything loosely bolted in place while l got it to fit correctly.

I'm going to loosen everything up, have someone hold down on the pipe and crank then bolts and nuts down hoping it will stay in place and if not I will elongate the mount bolt holes a little
