Subaru Impreza WRX STi Spec C Decat Exhaust Downpipe
The Subaru WRX STi Spec C Decat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 3" one-piece item. Increasing the bore of the downpipe and replacing the restrictive catalytic converter allows the exhaust gasses to flow much more freely, increasing the power output of the engine.
This downpipe has been specifically designed for the twin scroll turbo setup
Manufactured from T304 stainless steel
TIG welded, CNC machined flanges
Boss fitted to accept O2 (lambda) sensors
Fits Subaru Impreza WRX STi Spec C models with twin scroll turbo only.
Please note: Sold for off-road/track use only. Will not pass an MOT emissions test.
