aFe POWER 48-46208 Twisted Steel Exhaust Y-Pipe for 3.6L JKU

The aFe POWER 48-46208 is a Twisted Steel™ stainless steel exhaust Y-pipe built for 2012–2018 Jeep Wrangler JK 3.6L V6 4-door models that replaces the restrictive factory Y-pipe to improve exhaust flow and overall performance. Constructed from mandrel-bent 409 stainless steel with OE flanges and hand-MIG welding, its design merges two 2-inch inlets into a smooth 2.5-inch outlet collector that reduces turbulence and backpressure for better exhaust gas flow and durability both on and off the trail. The true merged collector and quality sealing flanges help maintain a leak-free connection, and because it bolts into the stock location with included hardware, installation is straightforward without modifications to the exhaust system. This upgrade is commonly paired with other performance mods like cold air intakes or cat-back exhausts to help unlock additional throttle response and efficiency.
