Description
 
Grimmspeed 44/45mm 2 Bolt Up Pipe External Wastegate 02-14 WRX / 04-20 STi ( 2 Bolt Connection )


An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; creating quicker turbo spool. The GrimmSpeed EWG has a larger diameter than a stock internal wastegate; this allows the exhaust gas to be released faster, which improves boost control, maintains maximum boost longer in the rpm range. All of these together will give you a 10-40 HP INCREASE. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates.

  • Includes Up Pipe to Turbo Gasket
  • Includes Manifold to Up Pipe Gasket
  • This Up Pipe is a 2 bolt connection fitting well with Perrin, Invidia, Agency Power, HKS and other 2 bolt models.
