  • 304 Stainless steel construction for durability and corrosion resistance
  • Lower EGT, better turbo efficiency and response
  • TIG welded flanges for leak-free, robust connections
  • Smooth transitions and free-flowing design
  • Woven titanium heat sleeve
  • Lower down pipe gasket
  • Compatible with factory or PPE Up-Pipes

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.
