Turn every start‑up into a statement and every mile into momentum. The STILLEN Cat‑Back Exhaust unlocks the 3.4L twin‑turbo V6’s personality with dyno‑proven gains of up to +10 wheel horsepower and +12 lb‑ft of torque, delivering crisp throttle response and a surge of mid‑range pull you can feel on the street, towing, or the trail. Built in Costa Mesa, California, the system installs cleanly as a true bolt‑on—no cutting, no welding—thanks to CNC‑machined flanges and mandrel‑bent 304 stainless tubing that maintain smooth, uninterrupted flow while resisting corrosion for years to come. The acoustics are tuned, not just loud: dual 2.5‑inch runs merge into a single performance muffler, shaping a deep, confident note that adds excitement under load and settles into a civilized presence at cruise.
For the adventure‑inclined, STILLEN considered the terrain as much as the dyno. The routing can be shortened at the axle to improve departure angle, adding confidence on break‑overs and rocky exits, while remaining compatible with hybrid and non‑hybrid models, 5.5‑ft and 6.5‑ft beds, and the factory bed step—so your truck’s capability and features stay intact. Finish it your way with polished stainless or black tips, and drive with peace of mind under a limited lifetime warranty that reflects STILLEN’s decades‑long commitment to American manufacturing and real‑world performance. This isn’t just an exhaust; it’s a refined release of the Tundra’s potential—engineered to perform, designed to endure, and tuned to thrill.
