So I got a new muffler put on at the local discount Mexicano auto shop (learned my lesson) and they rearranged my exhaust so the pipe forward of the muffler sits about 1/2 inch above the transmission support member and now rattles like a mother. Instead of getting the exhaust redone I'm thinking it would be a lot cheaper to just get some kind of heat resistant material like maybe a welding blanket and fix between the pipe and support member to cushion the rattle. Anything used it'd have to be ok with being in constant contact with the exhaust.

Found some 'High Temperature Resistant Fiberglass Pads - Heavy Duty Professional Welding Pad' on Amazon described good for soldering, welding or brazing.

Any thoughts on this or suggestion for a better material?

 

Got be closer than 1/2 inch or they wouldn't be rattling ?? The welding blanket isn't going to survive very long with the constant hammering of the two together...Find a way to raise the pipe or drop the crossmember and ding the pipe where it's too close...

 

Post a pic. The hanger on the mid pipe can be heated and reshaped to get the exhaust of the crossmember. Like corky said, a 1/2 “ won’t rattle. Locate the source of the rattle with a plastic hammer.
