After months of testing this system with various size piping our
engineering team decided that 3.5” piping is the best suited size
for a true free flowing design on the 135. The increase in piping
size decreases back pressure allowing the 135’s twin turbo to spool
even faster resulting in increased horsepower and torque throughout
the entire RPM range. Our engineering team also incorporated the
Active Autowerke Noise Cancellation Chamber to assist in
reducing/eliminating drone. Manufactured from 100% polished 304
stainless steel this bolt on system is a must for the 135 owner
looking to bring their BMW to new heights.
