H3 Mid pipe rattle

[mrchew]

Anyone ever had issues with exhaust rattle on brace bar after replacing headers and exhaust system. Mid pipe section keeps tapping brace bar no matter how tight I tightened the bolts.

Yep, check the rubber hangers. May need to be replaced.

Heck, I'd be loosening bolts and readjusting the system to make sure you have an inch of clearance between exhaust and crossmembers. The hangars should not have much tension on them - if they are dropping low enough that the exhaust can hit the frame, then the exhaust is misaligned

Looks like it was just the bolts loose from header to mid pipe. Causing the mid pipe to rotate and touch the brace bar. Any one ever replace their mid pipe? Mine looks pretty beat up.

First, are you talking V8 or I5?

I replaced the exhaust with Gibson split rear system and had muffler shop replace my header with the Orion headers. The muffler shop didn't tighten the bolts connecting to mid pipe good so it rotated and tapping on brace bar. Only used muffler shop because my exhaust manifold bolts were broken flush. I tightened the bolts from header to mid pipe after I rotated pipe back to have clearance and rattle is gone.

officially it was because the exhaust pipe was rattling on a heat shield. Bent it out of the way 1/2", good to go.
