HKS exhaust causing vibration

DYOOS · 10-22-2018, 05:30 PM

Hey guys, my uncle has an E92 N54 that he recently bought. It came with an HKS exhaust and he's getting some vibration in the rear trunk area. He's a mechanic, but he can't pinpoint the problem. He thinks it could be something to do with the seat belt though. Any ideas from folks who've run HKS exhaust or know of it and it's potential issues?

Aside from any drone only thing that would cause vibration is contact with the vehicle.

You'll have to sit in the back seat, and try to help him locate it.

If it's in the trunk, then you'll have to fold one of the seats down.

When you hear the vibration, put your hands on random places close to it to see if it stops.

Remember, sound travels, so it could be anywhere.

HKS is my favorite exhaust
