Product Description

Upgrade your 2009–2021 Toyota Tundra with a Flowmaster Flow FX Cat-Back Exhaust System engineered to improve exhaust flow, enhance performance, and deliver the deep, powerful tone expected from the Flow FX series. Both configurations feature dual 2.50-inch mandrel-bent tubing flowing into a Flow FX straight-through performance muffler, durable stainless steel construction, factory hanger locations, and all necessary installation hardware for a straightforward bolt-on installation.

Choose between two different exhaust configurations based on your preferred appearance and intended use. Part #717664 uses dual 2.50-inch tailpipes that exit to the sides behind the rear wheels and are finished with large 4.50-inch black ceramic-coated 304 stainless steel tips. This side-exit design is particularly beneficial for towing because the exhaust is directed away from the rear of the truck. Part #717786 uses dual 2.50-inch tailpipes that exit in front of the passenger-side rear tire and are finished with dual 4.00-inch double-wall black ceramic-coated 304 stainless steel tips.

Both systems are designed for 145-inch wheelbase Toyota Tundra models and use the factory hanger locations for easy installation. Select the correct part based on your Tundra's engine, wheelbase, cab/bed configuration, and desired exhaust exit style.
