Active Autowerke will be offering two exhaust options for the M2C.

Our Mid-Pipe is already available and we will have pictures and videos of the full system at the end of this week.

If you aren't familiar with our current S55 exhaust options, the main difference with our system compared to others is that we use a a single 3.5" mid pipe. The single design increases exhaust velocity and also deepens and smoothens the exhaust note. It's proven to reduce spool time and increase overall horsepower and torque. We chose the 3.5" diameter because it has proven to flow upwards of 800whp on turbocharged applications. BMW uses an exhaust pipe just over 3" on their N55 powered cars, so it didn't make sense to use a 3" pipe and offer a product that's more restrictive than the stock exhaust.
