AFE Y-PIPE 12-UP JK 4DR 3.6L MANU TRANS

The aFe Mach Force XP Jeep "Y-pipe" is designed to connect the stock converter with either the stock exhaust or aFe's Mach FORCE XP exhaust system. Designed also to accommodate aftermarket lift kits, this y-pipe features 2 x 2" into 1 x 2 1/2" stainless steel mandrel-bent tubing with OE flanges and 100% hand-TIG welded construction that resists corrosion. A true merged collector is used to increase and balance flow while reducing back pressure to diminish exhaust noise. The smooth curves and increased diameter helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability on and off the trails. All components are supplied for a hassle-free installation with no modifications necessary.
