Dynomax HD Super Turbo Mufflers

Product images may differ from actual product appearance.

You're at the end of your rope. It seems like every muffler you put on your RV either rusts away or gets blown apart from the extreme exhaust heat. The Dynomax HD Super Turbo was designed to be abused! Fully arc welded seams won't come apart and the aluminized construction means its rot resistant. Plus, with its 3'' inner flow tube, it outflows the competition by a long shot.
