Subaru Impreza GDA WRX STI 02-07 – Exhaust Sports Cat Downpipe

Our Impreza New Age Sports Cat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 3″ one-piece item with a built-in sports cat. 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.

Features:

• Manufactured from T304 stainless steel
• 3″ bore
• Built-in non type approved 200CPI sports cat
• TIG welded, CNC machined flanges
• Lower gasket and bolts included
