Invidia's Stainless Steel Up-pipe fit the Subaru WRX, STI, Legacy GT, Forester XT and Outback XT turbo models. The addition of a performance up-pipe is a favorite modification among die-hard Subaru tuners around the globe. Invidia's Subaru WRX up-pipe is a catless direct bolt on replacement for the factory up-pipe in your WRX or STI. Removing your WRX's restrictive factory up-pipe increases exhaust flow to the turbocharger and in return improves turbo spool, throttle response and power output by approx 7-10hp. The Invidia WRX/STI up-pipe has a bung for your stock EGT sensor, but can easily be plugged when used with later models that do not have an EGT in the up-pipe (plug not included). The Invidia up-pipe even includes replacement studs for added installation convenience. 02-05 WRX models have a pre-turbo catalyst, making this up-pipe a major performance improvement. Though the 06-07 WRX and 04-07 STI do not have a cat in the factory up-pipe, this product will still improve throttle response and drivability.

Part Number: HS02SW1UPP
Does not fit 2015+ WRX
Does not include gaskets
The build quality looks great and welds are very nice. the one flange was a bit warped but it may be that was on purpose to tighten on the gasket properly. Not sure. I will see if I can get a picture of it.
Easy install, great product for the price
Easy install and much better than the OEM catted up pipe for the 2006 Legacy GT
Great price worked great
