Our stainless steel 2nd decat for the Subaru Impreza GRB WRX STi replaces the standard restrictive catalytic converter with a stainless steel, one-piece item. Increasing the bore of the pipe and replacing the restrictive catalytic converter allows the exhaust gasses to flow much more freely, increasing the power output of the engine and improving throttle response.
Manufactured from T304 stainless steel
Built in sensor boss
TIG welded, CNC machined flanges
