aFe Power 48-06207 Y-Pipe for 12-18 Jeep Wrangler Unlimited JK 4 Door

The aFe "Y-pipes" is designed to connect the stock converter with either the stock exhaust or aFe's exhaust system's. 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-MIG welded construction that resists corrosion. A true merged collector is used to eliminate dead space that can cause turbulence and hinder flow that is prevalent with formed collectors. 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.
