This Twisted Steel Y-pipe for your JL replaces the restrictive factory Y-pipe between the catalytic converter and stock exhaust system or aFe's Mach FORCE Xp exhaust system. This Y-pipe features dual 2-1/4" into 2-1/2" 409 stainless steel mandrel-bent tubing with factory-style flange connections and 100% hand-MIG welded construction that resists corrosion. The smooth curves and increased diameter help remove restriction and keep exhaust gas flowing smoothly for improved performance and durability on and off the trails.
In-house dyno testing produced gains of up to +8 horsepower and +14 lb.-ft. of torque.
