[mike@x-ph.com]

Hi,
This product has been available for a while but very few people know about it because it was never officially launched by Evolution Racewerks. It still is not available on their website yet.
Last weekend during Bimmerfest it was displayed and was drawing a lot of attention for its high quality finish so i took some pictures so i can share with you. Similar to any other Evolution Racewerks product, these downpipes are designed and manufactured 100% in the United States. They are offered with a limited lifetime warranty, guaranteed to fit perfectly !!!

Evolution Racewerks new competition catless downpipes for the M5/M6 F chassis BMW.

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.



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 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.Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions. Since our catless downpipes delete the cataylic converter, we have more space. Thus, we use very long transitions. These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller.This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag).



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 in Brushed Finish.
