Description

Add dyno-proven power to your Subaru with this Twisted Steel Race down-pipe which produced up to +22 horsepower and +37 lbs. x ft. torque, as measured on our in-house dyno *(Dyno test results are from P/N 48-36801-HC). Brush finished 304 stainless steel tubing improves exhaust flow to deliver increased horsepower and torque. The down-pipe is 100% hand TIG-welded and uses a unique fabricated bellmouth design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased power. This direct bolt-on down-pipe requires no cutting or drilling for a hassle-free installation. This down-pipe was designed as a "Race" version for added performance and a more aggressive sound. This down pipe is constructed of 3" mandrel-bent, brush finished 304 stainless steel tubing for maximum flow and corrosion resistance. A unique fabricated bellmouth design increases exhaust velocity providing a free flowing wastegate. 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks. All hardware and brackets are included for a hassle-free installation.
