Want to install a downpipe on your B58 equipped BMW, but still need to pass emissions? Evolution Racewerks has the answer for you with their B58 Catted downpipe. The Evolution Racewerks Competition Series Catless Downpipes is constructed from 304 stainless steel, featuring mandrel bent piping. These are 100% TIG welded by in house fabricators and built in the USA!
The factory turbocharger turbine housing utilizes a V-Band flange which has been 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 remains positioned at the factory location. Also, since Evolution Racewerks uses a larger 4.5" pipe right after the turbocharger, turbo backpressure is significantly reduced, resulting in less exhaust turbulence and backpressure which again improves throttle response and decreasing turbo lag.
