Subaru Impreza GDA WRX STI 02-07 - 3" Exhaust Decat Downpipe

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 steel

• TIG welded, CNC machined flanges
• Boss fitted to accept O2 (lambda) sensors
• Gaskets included
