This racing exhaust has been discontinued by the manufacturer. Please contact us to discuss your race exhaust needs.These aFe x-pipes for the E9X M3 have been developed to minimize restrictions, maximize airflow, and reduce weight. aFe uses 2.5" 304 stainless pipe that replaces the original four catalytic converters with two metallic honeycomb 300-cell cats and a pair of resonators for reduced restriction and better durability on track. aFe measured gains of 21hp and 35ft-lbs with these pipes alone. This mid-section uses all of the factory connections, hangers, and gaskets and can be used with any axle-back rear mufflers. This system includes two resonators to dampen sound volume for tracks that have stricter sound limits. Factory bungs for original O2 sensors or wideband sensors are included.
Notice of Fault Codes/Check Engine Light - Using any cat-delete pipe could result in a check engine light and fault codes, even with sport cats. Although we have heard of cases where no check engine light appeared, these Racing downpipes are not designed to meet emissions testing and regulations. Race software that is specific to your mods is strongly advised to better adapt your car to a racing environment, keep the fault codes from appearing, optimize power gains, and improve general drivability. Our Epic Motorsports Race software is strongly encouraged to meet all of your tuning goals.
