Cat-Back Exhaust System, 304 Stainless Steel

The Stillen Cat-Back Exhaust is engineered to enhance the performance and sound of the 2022-2024 Toyota Tundra's 3.4L Twin Turbo V6 engine. This system provides dyno-verified gains of up to +10 WHP and +12 lb-ft of torque, contributing to stronger throttle response and improved everyday drivability. The dual 2.5-inch diameter tubing is crafted from mandrel-bent 304 stainless steel for optimal flow and long-term durability, merging into a single performance muffler designed to produce a deep, confident tone without harsh rasp or drone. The design prioritizes a true bolt-on installation, eliminating the need for cutting or welding, thanks to CNC-machined flanges. The system is compatible with both hybrid and non-hybrid models, as well as trucks equipped with 5.5 ft or 6.5 ft beds and the factory bed step. For off-road enthusiasts, the routing can be shortened at the axle to improve departure angle. It is available with either a polished stainless steel or black exhaust tip. While some customers have reported an increase in fuel economy, this has not been officially verified by Stillen. Important compatibility note: This exhaust system will not fit the Long Bed CrewMax Cab Tundra.
