High-Flow 304 Stainless Steel Down Pipe

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.
