Grimmspeed Up Pipe 3-Bolt Inlet 44mm EWG V-Band w/ Black Ceramic Coating (IWG bracket recommended)
An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo. This facilitates lower backpressure at the turbine, allowing for increased boost control, faster spool-up and greater top-end power. The GrimmSpeed EWG Up Pipe has a larger internal diameter than your stock unit, allowing a higher volume of exhaust gas to reach your turbo more efficiently. This helps maintain boost levels further into your RPM range. Depending on your specific setup, these improvements can net a 10-40 HP increase. An internal wastegate can create a larger amount of turbulence in exhaust flow through your turbine housing; moving to an external wastegate eliminates much of that turbulence and isolates the turbo from what little turbulence still exists as your wastegate opens and closes.
