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

Upgrade your L5P Duramax with the PPE Free-Flow Downpipe and eliminate the rusted, restrictive factory design. The PPE Down Pipe highlights unrestricted 3.5-inch diameter flow path, fully machined and TIG welded upper flange with factory-style V-band, and 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.

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.
