Compared to the stock downpipe, the finely polished Tomioka Racing down pipe is constructed from 100% SUS304 stainless steel with 3-inch pipe diameter compared to stock down pipe. Its bell-mouth inlet ensures high flow exhaust gas as opposed to the restrictive stock down pipe. Tomioka downpipe also features 2 bung locations for the O2 Sensor and temperature sensor.

Fitment is 100% bolt-on. All hangers are designed to fit at the respective stock locations. Despite its 3-inch piping diameter, it bolts-on to stock cat-back. In Tomioka style, all gaskets are included in the package to make sure seamless installation process. The Tomioka high flow catted downpipe is available for the Subaru 2002-2007 WRX/STi (GD) Sedan and 2008-2011 Subaru WRX/STi Hatch-back (GR).
