Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars. Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly. The G Chassis M3/M4 utilize a Y style mid pipe. However, both two downpipes are both on the right side of the engine. The left side downpipe connects to the "crossover" pipe as it crosses over to the left side underneath the transmission to connect to the midpipes. The right side downpipe connects directly to the mid pipe. Since this crossover pipe goes under the transmission, BMW squished the round pipe into an oval to give clearance. However, by going from a round tube to an oval, this causes turbulence inside the pipe which causes a restriction. We found that there is plenty of clearance to keep the tubing round, and thus we built our replacment Crossover Pipe without needing to squish the tubing. The factory crossover pipe ultilizes cast components so it is quite heavy. Our replacement Crossover Pipe is lighter and thus some weight savings can be had.
Our Competition Series Catless Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in house fabricators and built in the USA. 100% bolt on.
Our Crossover Pipe is designed to fit perfectly with either the factory or your aftermarket mid pipes. There are no compatibility issues whatsover. The Crossover Pipe will come by default with brushed finish.
Notice of Fault Codes/Check Engine Light - Using any Racing downpipe 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.
