    Twisted Steel Down Pipe by aFe Power

    aFe power introduces an all new Twisted Steel "Street" Down-Pipe for the Subaru WRX STI 2015-2017 with H4-2.5L engine. This down-pipe is designed using a 400 CPSI catalytic converter and mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horsepower and torque.

    The down-pipe is 100% hand TIG-welded and uses a 2-1/2" into 3" stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased power. In house testing produced a max gain of +22 horsepower and +37 ft. lbs. of torque verified by our in house dyno. This kit includes a second bung for either a wide-band O₂ gauge or auxiliary instrumentation.

    Features

    • This system utilizes a 400 CPSI (cell per square inch) catalytic converter for maximum flow
    • A unique 2.5" to 3" stepped design is used to increase exhaust velocity
    • Constructed of durable mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking
    • 100% hand TIG-Welded by certified craftsmen for race proven strength and durability
    • Includes second bung for either a wide-band O₂ gauge or auxiliary instrumentation
    • In house testing produced a max gain of +22 horsepower and +37 ft. lbs. of torque verified by our in house dyno

    Please Note: This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.
