Subaru Impreza GDA Twin Scroll WRX STI 01-06 - Exhaust Decat Downpipe
Our 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
