16 Best Exhaust For E46 M3 (2023 Updated)

The exhaust system on the e46 M3 is designed to work with the high performance engine to provide optimum power and torque. It is made up of a number of different parts including the exhaust manifold, catalytic converter, muffler, and exhaust tips.

The exhaust manifold is responsible for collecting the exhaust gases from the cylinders and directing them into the catalytic converter. The catalytic converter then breaks down the harmful gases into less harmful ones before they are expelled through the muffler and out the exhaust tips.

Conclusion

The stock exhaust on the e46 M3 is made of mild steel and consists of two main catalytic converters, a center resonator, and two rear mufflers. Over time, the stock exhaust can corrode and break down, causing performance issues.

A performance exhaust made of stainless steel will last longer and provide better performance by allowing the engine to breathe better.
