BMW E46 M3 CSL Rear Muffler Exhaust
Original BMW E46 M3 CSL Rear Silencer Muffler.
One of the many ways BMW lightened the M3 to make the CSL was be reducing the weight of the exhaust. By changing the layout and using different materials they were able to lose 11 lbs total.
A direct bolt on, this muffler the exhaust system will be 5 lbs lighter. Take the M3 to the next level with Genuine CSL parts.
