What Does the L5P Downpipe Do?

The L5P Downpipe on your 6.6L Duramax Diesel engine plays a crucial role in directing exhaust gases from the turbocharger turbine housing into the exhaust system. An aftermarket L5P Downpipe is typically larger in diameter than the factory version and may feature a high-flowing catalytic converter or remove it entirely.

By replacing the stock downpipe with a high-performance L5P Downpipe, you're allowing your Duramax 6.6L engine to expel exhaust gases more efficiently. This reduces turbo lag and increases horsepower by allowing the turbo to move gases away from the turbine faster. The factory downpipe often acts as a bottleneck, limiting exhaust flow and choking the engine's performance. With a high-flow L5P Downpipe, you can increase boost levels and unleash more power from your Duramax Diesel engine.
