Flowmaster Signature Series Cat-Back Exhaust System for 2009–2021 Toyota Tundra
Upgrade your 2009–2021 Toyota Tundra with the Flowmaster Signature Series Cat-Back Exhaust System (Part #737664). Designed for Tundra models equipped with 4.0L, 4.6L, 4.7L, or 5.7L engines, this premium 304 stainless steel cat-back exhaust delivers increased exhaust flow, improved performance, and Flowmaster’s signature deep, aggressive exhaust tone.
Featuring a straight-through Signature Series performance muffler, dual 2.50-inch mandrel-bent tubing, and large 4.50-inch Black PVD stainless steel exhaust tips, this system provides excellent horsepower potential while maintaining a comfortable interior sound level for daily driving and towing.
