Perfectly compliment the refined, yet aggressive styling of the BMW 135i with an axle-back exhaust from Agency Power. The fully stainless steel construction is TIG welded and fully polished to a mirror finished. The dual titanium tips increase the presence of your 135i and add a touch of style to an otherwise subtle rear end. The axle back muffler fits to the stock mid-pipe to not only save weight, but improve performance on and off the track. The muffler deletes the factory flapper valve design on the original muffler to give you the full sound of performance without drone.
