Subaru Impreza GDA WRX STI 01-07 - 3-2.5" Exhaust Decat Downpipe

Our Decat Downpipe compatible with the Subaru Impreza New Age replaces the standard restrictive downpipe and catalytic converters with a stainless steel, one-piece item. Increasing the bore of the downpipe and replacing the restrictive catalytic converters allows the exhaust gasses to flow much more freely, increasing the power output of the engine.Features:Manufactured from T304 stainless steel3" bore with 2.5" outletTIG welded, CNC machined flangesBoss fitted to accept O2 (lambda) sensorsGaskets included
