Tomei Stainless Race Downpipe Subaru WRX STI 04-07

Description

The stock Downpipes on the Subaru WRX/STI are restrictive and therefore limit the amount of horsepower your engine can produce. Tomei Race Straight Downpipe dramatically improves exhaust flow and significantly reduces over 53% of weight vs. the stock Downpipe. Addition to massive torque and power increases, lightness dramatically improves handling. Increasing the diameter from 60.5mm to 76.3mm results in increased flow while changing the material from steel to 304SS drastically reduces weight from 22.71lbs to 9.48lbs.
