Active Autowerke| -=Flash Sale=- Signature 135 Exhaust|Limited Time offer!

[SflBimmer8484]

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 BMW 135i exhaust. The increase in piping size decreases back pressure allowing the 135i’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 in the BMW 135i exhaust. Manufactured from 100% polished 304 stainless steel this bolt on system is a must for the 135i owner looking to bring their BMW to new heights. Combined with our Siganture BMW 135i Downpipe, the horsepower gains are extreme.
