Adding sound to your car is one of the first things that any car enthusiast thinks of. Adding sound to the E46 M3's S54 engine is a MUST!
Magnaflow's cat-back exhaust will allow the driver to hear the S54 inline 6 sing all the way to redline. The design of this exhaust is similar to a lot of Magnaflow systems consisting of a straight through flow which eliminates any restrictions that the factory BMW system has. This will unleash extra horsepower and torque while maintaining efficiency.
All Magnaflow systems are built in the USA and feature a lifetime warranty!
