Product details
Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2007-2021 Toyota Tundra with the 4.7 or 5.7-liter engine. This system uses a Flow FX series muffler for an aggressive to moderate sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 5 hp and 6 lb-ft of torque at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation.
