Top 6 Best BMW E9X M3 Exhaust Systems

There’s a good reason why aftermarket exhaust systems are among the first mods that most BMW E90/E92 M3 owners get for their vehicles. Whether it’s the 4-door sedan or the 2-door coupe, the BMW M3 E90/E92 exhaust sound is infamous for being mute as heck.

And although BMW did a really great job in creating one of the best naturally-aspirated cars that ever existed, they still have the mindset of a luxury carmaker that prefers to emphasize silence over a loud exhaust note. 

Aside from full exhaust systems, there is another way of introducing a new auditory excitement to your BMW E90/E92 M3, and that is the removal of the primary catalytic converters. Car enthusiasts who aren’t big fans of exhaust systems replace their car’s two central pairs of cats with straight pipes (also known as test pipes).

This can be a cost-effective method of achieving a wild and aggressive exhaust note for your vehicle. This venture can be pretty risky, especially if you’re not experienced enough, because it may mess your exhaust up big time.

It will also inevitably lead some cops on your tail because straight pipes are notorious for being obnoxiously loud.

If you’ve finally decided to get an aftermarket exhaust system instead of DYI-ing your way to a better-sounding car, then we’ve got something special for you.

Scroll down to see the list of what we think are the best aftermarket exhaust systems available for the BMW E90/E92 M3. Whether it’s for sound or for power, we’ve got you covered.
