During testing our shop Q60 with our VR30 Full Downpipes, and Red Alpha Tune, our Engine Calibrators saw 20 horsepower gains over our VR30 Race Lower Downpipes! The power came on earlier and the twin turbo’s spool-up was significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. We were able to design a superior product because of our superior engineering.Big HP Gains Over Lower DownpipesFull 3″ Stainless Steel Construction Including Brackets and FlangesIncluded 2.5″ to 3.0″ Adapter Allows You to Run Either Stock Catback System or Aftermarket SystemsMandrel Bent Tubing for the Best Exhaust FlowTurbine Flange Offers a Smooth Transition from the Turbine Outlet into the 3″ TubeIncludes all Gaskets Rated to Over 800 Degrees Celsius and all Necessary HardwareO2 Sensor Tubes Extend to Meet OEM Location.
