Product Name: PPE High-Flow 304 Stainless Steel Down Pipe - 15.5-16 Duramax LML Manufacturer: PPE Manufacturer Part #: 117000700 Thoroughbred Diesel Part #: PPE117000700 Fitment Notes: 2015.5-2016 GM Duramax
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.
Note: Only compatible with LML trucks with a three-bolt flange at the connection to the exhaust pipe.
