22- Toyota Tundra 3.4L Cat Back Exhaust

The Flowmaster 22-Toyota Tundra 3.4L Cat Back Exhaust (FlowFX model 718143) is a dual side-exit cat-back exhaust system engineered for the 2022–2023 Toyota Tundra V6. This stainless steel system replaces the restrictive factory exhaust with a 2.5-inch diameter tube design and exits through quad black 4-inch tips, delivering measurable improvements in exhaust scavenging and engine breathing while maintaining a refined tone across the RPM range.

The 2.5-inch tube diameter is sized to balance flow velocity and volume for the Tundra's naturally aspirated V6 engine, preventing excessive backpressure while maintaining low-end responsiveness. Flowmaster's signature chamber technology reduces turbo whistle and drone, a critical consideration for full-size truck owners who log highway miles. The stainless steel construction resists salt-air corrosion and thermal cycling, extending service life well beyond painted steel systems. The dual side exits provide aggressive visual presence without requiring undercarriage modification, and the symmetrical routing maintains optimal suspension geometry for off-road use.

This system is purpose-built for Tundra owners seeking a performance upgrade without sacrificing drivability—truck owners running towing loads, hauling cargo, or pursuing light off-road recovery benefit from improved exhaust flow under load. The bolt-on installation integrates with the factory mounting points, eliminating the need for welding or custom fabrication. At 50 pounds, the system is comparable in weight to OEM exhaust while offering superior thermal management and durability.

Flowmaster cat-back systems occupy the middle ground between stock exhausts and full header kits—they preserve catalytic converter function and emissions compliance while opening up the flow path downstream. For 2022–2023 Tundra buyers, this FlowFX platform represents the production-ready balance between acoustic character and refined highway manners.
