Dynaflex is the premier manufacturer of chrome plated, stainless steel, as well as plain and aluminized carbon steel exhaust products for the heavy duty trucking industry. In almost 30 years of operation, Dynaflex has introduced, to the industry, innovative products that have since been duplicated by our competitors. We maintain a level of quality chrome plating that has not been duplicated in the industry. Dynaflex offers aftermarket replacement products for all models of Cummins, Detroit Diesel, Freightliner, General Motors, Ford, International Harvester, Kenworth, Mack, Peterbilt and Western Star as well as generic products that will adapt to a number of other applications. We recently introduced our "Z" Series Combo Monster Stacks providing an easy to handle and assemble product to our line.
