High-Flow 304 Stainless Steel Down Pipe for GM 6.6L Duramax

The factory downpipe is constructed from two pieces of formed sheet metal welded to an oval pipe. The factory design features a sharp, abrupt transition immediately after the turbine flange, which restricts exhaust flow and impedes performance.

Upgrade your LB7 with the PPE Free-Flow Downpipe and eliminate the rusted, restrictive factory design. Crafted from durable 304 stainless steel, this downpipe features a robust half-inch turbine flange, a CNC-machined lower flange, and smooth, optimized transitions for unobstructed exhaust flow. To further enhance performance, it comes with a woven titanium sleeve that effectively insulates heat, protecting the engine bay.

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.
