TurboXS Downpipes

Made from heavy gauge 4" inside diameter 304 stainless steel, the TXS downpipe is larger than any other WRX/Sti/FXT downpipe on the market. Why is that important? Because, size does matter. Turbochargers work best when there is large pressure and temperature differential across the turbine wheel. Having a large, free flowing downpipe is what gives you that large pressure and temperature differential.

The downpipe tapers to 3" towards the tail and even includes a pre-welded 02 sensor bung for installing an aftermarket wideband O2 sensor OEM style doughnut gasket enhances flexibility, durability and sealing as opposed to lower quality flex joints. All TurboXS Exhaust components feature a 5 year warranty! Exhaust components fit both the manual and automatic 2002-04 WRX. *Turbo-back exhaust systems are for off road use only and are not street legal
