I was taking off my muffler bolts to put on new ones and try to fix this rattling sound I get from the exhaust when I go into too high of a gear. It looked like a normal silver looking wire wired to a ring, and the ring was bolted into the muffler-to-catalytic pipe part. Does everyone else's G35 have that too?

I was wondering what it's for.

Exhaust electrolysis


It reduces static buildup to the pipes.... Hard to stomach but it is what it is.

Oh thanks Eric!
