Product Description
Our Spec C Decat Downpipe compatible with the Subaru WRX STi 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
Features:
Manufactured from T304 stainless steel
3" bore
Twin scroll
TIG welded, CNC machined flanges
Boss fitted to accept O2 (lambda) sensors
