Active Autowerke is proud to release the newest addition to our Signature line of exhaust systems. There has been an overwhelming demand for this system and we bring it to you with great pride.

After months of testing this system with 3” piping our engineering team decided that 3.5” piping is the most adequate size for a free flowing design. The increase in piping size decreases back pressure allowing the 135’s twin turbo to spool even faster resulting in increased horsepower and torque.
The incorporation of the noise cancellation chamber on the side of the exhaust reduces/eliminates drone.

This is a must for the 135 enthusiast .
