Step 2

Spray a small amount of oil onto both hangers (circled in green) which will aid the removal of the exhaust.

Whilst holding the muffler slide the pins out of the rubber exhaust hangers. This will take some force.

Here is an image of the stock muffler compared to our new straight pipe system. The stock muffler is surprisingly light despite its size.

Step 4

Re-install your new exhaust by reversing the process. Additional oil for lubrication will help sliding into the rubber hangers.
