Berk Technology BT1801-S-HPC Axle-Back Race Exhaust w/ Satin Black Ceramic Coating 08+ BMW 135i E82
The Berk Technology rear muffler delete is a no compromise approach to maximum horsepower gains in a lightweight elegant package. The muffler delete features a completely straight through design with zero obstructions to flow. The twin 80mm dual wall tips finish off the look with a classy appearance that doesn't take away from the original look of the car. This is the identical system we use on our own championship winning race cars.
