This GP Moto turboback features a stainless steel bell-mouth downpipe w/ additonal wideband O2 bung that mates to a titanium catback section w/ resonator. This is a catless system that is a direct bolt on for any 02+ WRX or STi. In total, this system weighs just 28 pounds! It also has an adjustable silencer that can either be removed or dialed in.
These are cut differently than OEM exhausts or any other exhaust on the market, so they cannot be split up -- the titanium catback will only mate to a GP Moto downpipe.
PM for unbelievable pricing -- this system can be had for less than most stainless steel turbobacks on the market! The majority of this exhaust is titanium!
