Injen Uppipe Subaru WRX/STI Manual 02-06

Typically the first mod for WRX enthusiasts, the Injen up-pipe eliminates the first of three factory catalytic converters in the Impreza WRX and Sti. This is one of the most popular modifications due to the power gains and protection to your turbo. By eliminating the pre-turbo catalytic converter, it eliminates the possibility of the catalytic converter deteriorating and breaking apart, which can send metal pieces into your turbine and in turn damaging your turbo. In addition, the additional flow to your turbo will result in quicker spool time so you can get a better launch! The SES1200UP is built from T304 2" Stainless Steel tubing throughout, maximizing exhaust flow for a faster turbo response. Injen's design incorporates 1/2" die casted and machined flanges and even includes studs and an O2 Sensor bung for a direct replacement. Note: like most aftermarket up-pipes for the WRX, this removes 1 of the 3 factory catalytic converters. 57mm piping diameter.

Fits: Subaru WRX, Wagon, 02-06 and STI 2.5L 04-06. (Manual Only)

About Manufacturer: Injen

Injen Technology

Injen Technology has made it a point to stay at the forefront of performance technology making only the best air intake one can envision. In 1999 Injen was faced with such a strong demand in both US and Canada that in order to meet production schedules it became essential to branch out and add a second building.

In 2003, Injen Technology launched our Super SES stainless steel cat-back exhaust systems complimenting our line of air intake systems. Each exhaust system was equipped with the Injen signature style slanted mufflers and featured highly polished stainless steel.
