BMW 135i Aftermarket Muffler Exhaust Install / Compare Muffler delete exhaust sound to stock

I replaced my Dinan muffler with an OEM one, but this video will apply for anyone looking to install an aftermarket muffler on a BMW 135i, and is also applicable to many other models.
At 10:34 I also compare sounds with no muffler (muffler delete) to the stock muffler.
