B58 High Flow Catted Downpipe
Restrictions in the exhaust system rob 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 Evolution Racewerks Competition Series Catless Downpipes is constructed out304-grade304 grade stainless steel and utilize mandrel bent piping. They 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 is positioned at the factory location. Also, since they use a larger 4.5" pipe right after the turbocharger, turbo backpressure is significantly reduced. This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag).
