The aFe Mach Force XP Jeep Y-Pipe is designed to connect your Jeep's factory converter with either the exhaust from the factory or aFe's Mach Force XP exhaust system. It accommodat es aftermarket lift kits and features 2" x 2" into 1" x 2.5" stainless steel mandrel-bent tubing with OE flanges and hand-MIG welded construction, which is corrosion-resistant. Its smooth curves and increased diameter help to reduce restriction and keep exhaust gasses flowing smoothly for improved performance and durability. All necessary hardware is included for easy installation; no modifications to your vehicle are required. The new 3.6L Pentastar power plant on the 2012-2013 JKs changed the positioning of the stock Y-Pipe. When a lift kit is installed the clearance between the exhaust and the driveshaft is dramatically reduced and the risk of contact damage is greatly increased, especially when traveling in rough off-road terrain. The aFe Mach Force XP Y-Pipe re-routes the exhaust to provide the necessary clearance to clear the drive shaft. It is recommended for 2012 and newer Jeep Wrangler JKs with 3.5" lift or higher, especially those used in extreme off-road conditions. It is required for installation of 4" or higher aftermarket lift kits on 2012 and newer Jeep Wrangler JK and JK Unlimiteds. The aFe Y-Pipe maintains the factory "Loop" to keep engine back-pressure equal. Show more
