---tab Description--- Experience a significant boost in performance with our 4" High Flow, 2-Piece Downpipe. Crafted from high-quality 304 Stainless Steel, it not only enhances exhaust flow but also simplifies installation when compared to the stock unit. This downpipe is designed as a factory replacement, ensuring compatibility with any exhaust system and turbocharger that fits the factory location. Elevate your Powerstroke's potential with SPELAB! What does a downpipe do? The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether. By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.
