Tsudo 08-16 Impreza WRX/STI 3in BellMouth Wastegate Downpipe

This is a brand new complete 2008-2010 Subaru Impreza WRX and STI 76mm / 3" Down-pipe. This features high-flow mandrel bent tubing which increases horsepower and decreases turbo spool time. Note: This downpipe removes the OEM catalytic converter, which will trigger a CEL (check engine light) because of increased emissions. In this case, a CEL fix will be required to disable the light, but the light does not affect performance. Super high strength cast iron bellmouth with high temp coating. Huge 3" tubing eliminates backpressure to decrease turbo spool time and increase power. Manufactured from 100% stainless steel with silver polished finish. T-304 stainless steel will never rust and provides the ultimate durability. CNC machine mandrel-bent 3" stainless steel tubing for maximum exhaust flow. CNC cut flanges and robotic TIG welded. O2 Sensor bung welded in OEM location. 25% lighter than stock OEM exhaust system. Utilizes the factory exhaust bracket. Includes all necessary flanges, bolts, and gaskets for installation. Easy bolt-on installation with typical hand tools, no welding or cutting required. For off-road race / track use only.
