Introducing our new Competition Series Catless Mid (H) Pipes for your twin turbo S58 engine!

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. The factory turbocharger turbine housing utilizes a 3.5" V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor is positioned at the factory location. The factory donut flange design is retained. 100% bolt on.

Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system. There are no compatibility issues whatsover. The downpipes will come by default with brushed finish.

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.

Midpipe Crossover Pipe

The G80/G82 utilizes a Y style Midpipe. Since both downpipes on are on the right side of the vehicle, the Midpipe Crossover Pipe connects the left side downpipe to the left side of the Y midpipe. The factory crossover pipe goes underneath the transmission and is ovalized for clearance. Our Midpipe Crossover Pipe does not ovalize but retains a round shape for ideal flow conditions.
