aFe power introduces an all new Twisted Steel "Street" Down-Pipe for the Ford Mustang EcoBoost 15-16 with I4-2.3L engine. This down-pipe is designed using a 400 cpsi catalytic converter and 3"mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horsepower and torque. In house testing produced a max gain of +13 horsepower and +15 ft. lbs. of torque verified by our in house dyno. The down-pipe is 100% hand TIG-welded and includes a second bung for either a wide-band O₂ gauge or auxiliary instrumentation.
