Flo-Pro Mufflers & Resonators

Flo-Pro builds exhaust parts for diesel trucks, and this page lists its mufflers and resonators along with some complete systems sold with or without a muffler. Muffler styles include stainless truck mufflers, Max mufflers and Twister mufflers, plus a stainless diesel resonator.

These are sold by size rather than by vehicle. Titles give the body dimensions, the inlet and outlet size in inches and the overall length. Match the pipe diameter on your truck and make sure the body will fit under the cab or frame. A resonator is a quieter, simpler choice for removing drone, and a muffler lowers the overall volume more.

Complete systems are listed by diesel engine, such as the 6.6L Duramax, the 7.3L Powerstroke, the 5.9L Cummins and the 6.5L diesel, with the year range in the title. Some come as downpipe-back or turbo-back runs with no muffler, so you can choose the muffler separately. Others are sold with the muffler included.

Check the title carefully for the engine, pipe size and whether a muffler is included. For other makers, see the full Mufflers & Resonators range. Priced in Canadian dollars and ships across Canada.
