Upgrade your OEM catalytic converters to Fabspeed 200-Cell Sportcats to reduce exhaust backpressure and free up horsepower and torque. The 200-Cell Sportcats are OBDII. The Sportcats comply with 49-state emissions and inspections. They will also work with the stock secondary catalytic converters or the Fabspeed X-pipe catalyic bypass pipe. Give your E90/E92/E93 M3 a boost in power, while improving it's exhaust note. Please note - the 200 Cell Sport Cats are designed to not throw any Check Engine Lights, however some have reported occasional CELs.
**Installation of the high flow sport cats will require some modification for 100% fitment**
