Compatible with the factory or aftermarket exhaust systems. Track tested durability. Includes all hardware for complete installation. Limited Lifetime Warranty. 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 factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction.  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/catalytic converter with our Competition Series Catless Downpipe, more power is unleashed!  You will feel the difference instantly.  The BMW XM (G09) has 2 primary catalytic converters and 2 secondary catalytic converters for a total of 4 catalytic converters.  Our Competition Series Catless Downpipes replace both the primary and secondary section
