High-Flow 304 Stainless Steel Down Pipe

The factory LML down pipe makes an abrupt directional change immediately after the turbine flange, which restricts exhaust flow and impedes performance. The indentations in the piping can further impede exhaust flow.

Upgrade your Duramax with the PPE Free-Flow Downpipe and eliminate the rusted, restrictive factory design. The PPE Down Pipe highlights unrestricted 3-inch diameter flow path all-along, fully machined and TIG welded upper and lower flanges, and three-inch 304 stainless steel piping. It ensures smooth transitions for unobstructed exhaust flow. To further enhance performance, it comes with a woven titanium sleeve that effectively insulates heat, protecting the engine bay.

Duramax High-Flow 304 Stainless Steel Down Pipe

Note: Only compatible with 2011-2015 LML trucks that uses a clamp at the connection to the exhaust pipe.

Quality manufacturing

The cast and machined flanges are of quality I wouldn't want to hide under a clamp. They blend well with the pipe and would appear to have good flow characteristics. Everything fit right up as it should. I did end up needing to add a third hose clamp to the middle of the wrap to keep it from sliding down the pipe.
