Stock Sound Supressor Removal

Park your car in a smooth level place
Jack up your vehicle with the wheels turned to the left
From the passenger's side you should be able to see the stock sound suppressor
Once you locate the sound suppressor you'll need to remove the snap-ring. It can take a little bit of twisting to do this and can sometimes be easier with the undertray removed.
With the snap-ring removed you can easily remove the suppressor, if it's stuck from road grime you can thread a m5 bolt into it and remove it from the turbo.
Now lubricate the o-ring with the provided lubricant and install it onto the sound suppressor.
With the o-ring installed and lubricated you can put the new COBB Sound Suppression Chamber in place.
Go ahead and re-install the o-ring by placing it over the suppressor and sliding it downwards before expanding it using your snap-ring pliers and pushing down on the back side with a screwdriver to get it to movedown evenly.
You're all done! Go out and enjoy!
