Product Name: PPE High-Flow 304 Stainless Steel Down Pipe - 11-15 Duramax LML Manufacturer: PPE Manufacturer Part #: 117000600 Thoroughbred Diesel Part #: PPE117000600 Fitment Notes: 2011-2015 GM 6.6L Duramax LML
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 2011-2015 LML trucks that uses a clamp at the connection to the exhaust pipe.
