FS: ER Competition Series 4" Catless DP
Evolution Racewerks Competition Series Catless Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by Evolution Racewerks' in house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a V-Band flange which Evolution Racewerks 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. Since the outlet of the turbocharger is 3.5" and the factory exhaust system is 3", the factory downpipes reduces size using short transitions from 3.5" before the catalytic convert and 3" afterwards. Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions. Since Evolution Racewerks' catless downpipes delete the cataylic converter, they have more space. Thus, they use very long transitions. These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller. Also, since Evolution Racewerks utilize a larger 4" 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). Evolution Racewerks downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system. Going for $499 new, selling for $339 OBO and will pay shipping.

Sharing some info since I have been IM'd this ?? twice. I ran this ER DP on my car for 18 months with JB4 and had zero issues with overall drivability and no rotten egg smell either. Our 3.0 liter engines with direct injection does outstanding job optimizing fuel. The overall sound is more aggressive, I kept stock exhaust and cold start sounded simply amazing (15 year old son would leave his door open to hear).
