This BlackHeart Y-pipe is for 1987-2006 Jeep Wrangler with an LS or LT engine. Built with 18 gauge 304 stainless steel for lightweight, strength and superior corrosion resistance. The inlets are 2-1/2 inch and connect directly to BlackHeart headers for the same application. The 3 inch outlet provides excellent flow while still providing a high-tuck connection for clearance. The V-band connections and dual O2 bungs provide convenience and multiple mounting options for related accessories.
