grinding the rear bumper?

Ash_Rah · 08-31-2015, 04:03 PM

i got a new exhaust and it's touching the bumper. it would vibrate on idle sometimes. i wanted to know if there's any easy fix for it. Can i grind down the bumper little bit? would it damage(crack) the paint?

I would get some extended rubber exhaust hangers instead of cutting up the bumper.

Why don't you just have the muffler properly installed....and don't cut up bumper

Only thing you need to do is remove the metal bracket that the rubber hanger attaches to. Is fasten with one bolt onto the car chassis. Place couple of washers and re-install.

Agreed with others, it's not installed correctly. Maybe take it back to the shop to get it fixed. I mean this is hard to screw up if the shop is competent. Or maybe take it to another shop with a good reputation.

Agreed just get the muffler hangers fixed you don't want to cut into the bumper
