The addition of a performance uppipe is a favorite modification among die-hard Subaru tuners around the globe. Prosport's Subaru WRX uppipe is a catless direct bolt on replacement for the factory uppipe in your 02-07 WRX or STI. Removing your WRX's restrictive factory uppipe increases exhaust flow to the turbocharger and in return improves turbo spool, throttle response and power output by approx 7-10hp.
Our uppipe includes the bung for the EGT sensor as well as 5 replacement studs for added installation convenience. 02-05 WRX models have a pre-turbo catalyst, making this uppipe a major performance improvement. Though the 06-07 WRX and 04-07 STI do not have a cat in the factory uppipe, this product will still improve throttle response and drivability
They are fully constructed out of T304 stainless steel, including the flanges!
