Product Details
We've greatly enjoyed working with Evolution Racewerks throughout the years so when they came to us with the new BMW F82 M4 for developmental testing we jumped at the chance to be a part of it again. After testing the car at Buttonwillow raceway, with Achilles Motorsports driver VJ Mirzayan at the wheel, Evolution Racewerks quickly learned the weak points of the car. They packed things up, and heading home to tear the car apart. After all the sparks had settled, these fantastic new downpipes were one of the first parts created.

Restrictions in the exhaust system robs horsepower and torque especially on the new BMW F80 M3 & F82 M4. So, removing any exhaust flow restrictions will increase horsepower and torque significantly. The catalytic converter found in the factory downpipe is a big culprit of this and robs power significantly. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe (which houses the catalytic converter) with an Evolution Racewerks Competition Series Catless Downpipe, more power is instantly unleashed!
