Not just another "me too" midpipe for your BMW 135i. The MadDad midpipe is unique. While other midpipes delete lower factory cats just as the MadDad does for the added power, only MadDad replaces them with mini-resonators to take their place. These custom made mini-resonators look like metal substrate cats and they are positioned in the oem staggered layout of the factory catalytic conveters giving the MadDad midpipe an uncanny OEM type look. MadDad BMW products are designed to look and fit as if they were factory performance options. That means unpolished T304SS to emphasis the "non" tuner look. Mirror polished SS is always a dead give away that your running aftermarket parts. Easy 15 min bolt-on application yielding 10-15lbs/10hp over a broad rpm range right up to redline. Dyno image shows honest bolt on gains comparing the factory midpipe to the MadDad with no other modifications, exact same dyno parameters, on the exact same car on the same morning(within 90 mins. of each other).
Engineered and built 100% in the U.S.A
T304SS including the flanges
Custom made staggered layout mini-resonators maintain an oem type catted look.
Custom tuning of resonators specific to 1 Series sound dynamic helps minimize cabin drone
Eliminates large factory resonator(size of a muffler) for increased performance
Larger diameter for increased flow/better throttle response
Easy, honest, dyno proven bolt-on performance. Dyno chart shows difference made from installing just the midpipe. Same day, same car, same conditions, same dyno settings, same dyno.
Works with factory axleback or any brand performance axleback designed to fit with the factory midpipe, including: AA, aFe, Berk, CP-E and others. For best in-cabin sound quality we reommend a Maddad Whisper Series axleback.
