ok i took my stock exhuast off two weeks ago and i belive that there was 4 clamp holes. one which was not a clamp but look like at circular rubber thingy. anyone know what it does. it was near the front of the exhuast. and does anyone have pics of how to properly install a flowmaster axle back. or atleast ver detailed

 

anyone

 

wow no one is helpful on thursdays

 

It sounds like a rubber grommet. It goes inside the exhaust hangar.

 

the rubber thingy is a vibration dampener or something. its not needed when you get a new axleback
