The Drop Engineering E46 M3 Stainless Steel Muffler is precision manufactured using aircraft quality T-304 stainless steel to provide the highest level of performance. Stainless steel tubes offer both exceptional physical properties with notable resistance to the corrosive agents found in exhaust emissions. Drop Engineering utilizes mandrel bending to produce a precise fit and uninterrupted exhaust flow. Mandrel bent Drop Engineering Exhaust Systems are superior to the restrictive design of the stock exhaust. A Drop Engineering Exhaust System will allow your engine to discharge exhaust gas easier, resulting in more horsepower and torque while extending overall engine life. Each system has flawless bolt-on installation and is backed by an excellent lifetime warranty.

BMW E46 M3s utilizing the Drop Engineering Stainless Steel Muffler will notice power gains accompanied with reduced weight, polished pipes, and a sporty exhaust note to show off the power of BMW’s raw inline six engine under heavy throttle without the annoying drone when cruising down the highway. It will fit with both stock and aftermarket midpipes that utilize the same connectors, as well as line up with the factory exhaust hanger locations.
