Berk Technology BT1801-S Axle-Back Race Exhaust 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.

Features:

• The most free flowing design possible. Zero baffles, zero restrictions, maximum flow.
• Single 3" merged to dual 2.5" pipes.
• Finished off with twin 80mm dual wall tips
• Gives the 135i a very aggressive exhaust tone.
• Extremely lightweight system.
• Fits both N54 & N55 models.
