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.\u003c\/p\u003e\n\u003cp\u003eFor 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—\u003cb\u003eengineered to perform, designed to endure, and tuned to thrill.\u003c\/b\u003e\u003c\/p\u003e","brand":"STILLEN","offers":[{"title":"Polished Stainless Steel Tip","offer_id":44677749473575,"sku":"509355","price":1029.99,"currency_code":"USD","in_stock":true},{"title":"Black Tip","offer_id":44677749440807,"sku":"509356","price":1107.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0144\/4275\/8230\/files\/509355_IMG001_2022-23_Toyota_Tundra_STILLEN_Cat-Back_Exhaust_Polished_Tip.jpg?v=1753821218"},{"product_id":"2024-toyota-tacoma-trupower-by-stillen-cold-air-intake","title":"2024+ Toyota Tacoma Trupower by STILLEN Cold Air Intake - TP403212 \/ 213 \/ 214 \/ 215 \/ 216","description":"\u003ch2\u003e\u003cstrong\u003eSTILLEN TruPower Cold Air Intake for 2024+ Tacoma\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eUnlock the full potential of your 2024+ Toyota Tacoma with the STILLEN TruPower Cold Air Intake, a game-changing upgrade designed for maximum airflow, throttle response, and horsepower.

Whether you’re towing, cruising, or idling, that radiant heat preloads your intercooler fluid, hurting intake air temperatures and forcing the ECU to compensate with reduced timing and added fuel.\u003c\/p\u003e\n\u003cp\u003eThe STILLEN Intercooler Reservoir Relocation Kit separates the intercooler system from the radiator, giving it a \u003cstrong\u003ededicated path for thermal management\u003c\/strong\u003e.

Since STILLEN released its TruPower Cold Air Scoop for the Silverado, and Sierra, in 2019, the question never stopped: when is the full cold air intake coming? The answer is now. What took so long was not indifference. It was doing the job the right way.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eMore Than Just an Airbox and a Tube\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eBefore a single prototype was cut, the STILLEN team set out to understand the factory system from the ground up. The first clue had already surfaced during scoop development, when opening the front inlet grille area gained nearly 10 horsepower on the dyno. If the front end was that choked, the rest of the system almost certainly was too. The factory intake channels air through the front core support, which is a good concept, but puts a hard ceiling on total airflow volume. Once it saturates, there is nowhere else for the engine to pull from.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFollowing the Temperature Data\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eRather than guess, STILLEN instrumented the engine bay with temperature sensors and mapped thermal conditions across the entire space. More airflow from the wrong location means hotter air, larger molecules, and a less efficient burn. The net power gain can be deceptively small. What the data revealed was a consistent low-temperature zone behind the headlight, inside an opening in the frame rails. Protected from engine heat by the wheel liner, this location pulls naturally ventilated air from outside the engine bay and became the foundation of the entire airbox design.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eClearing Out the Turbulence\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe factory intake tube is loaded with resonators, baffles, and muffler chambers engineered for mass-market refinement. Those chambers slow the air, create turbulence, and force the charge to work harder before it ever reaches the throttle body. STILLEN eliminated all of it. The replacement tube runs a straight, smooth path from airbox to engine, maximizing velocity and minimizing restriction.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eThe Filter as a Sealing System\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe STILLEN filter incorporates a secondary flange that extends past the filter media and interfaces directly with the airbox housing, creating a fully sealed joint at both the tube connection and the box. Every molecule of intake air goes through the element. None of it bypasses.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhat It Means Behind the Wheel\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eTwo years of development and real-world beta testing produced results that speak for themselves. The intake alone delivered 15 WHP and 12 lb-ft of torque on the dyno. Paired with the STILLEN TruPower Cold Air Scoop, those numbers swelled to 24 WHP and 21 lb-ft at the rear wheels.* Exceptional figures for a naturally aspirated V8. As a bonus, beta testers also often reported 1-2 MPG gains in real-world driving. Proof that when the engine breathes better, everything downstream improves: response off the pedal, engine efficiency, power under load, and consistency that holds up whether you are towing, hauling, or just running hard.\u003c\/p\u003e\n\u003ch2\u003e\u003cem\u003e\u003cstrong\u003e*Results May Vary!\u003c\/strong\u003e\u003c\/em\u003e\u003c\/h2\u003e","brand":"STILLEN","offers":[{"title":"5.3L \/ Oiled","offer_id":51316618101031,"sku":"TP403504","price":399.99,"currency_code":"USD","in_stock":true},{"title":"5.3L \/ Dry","offer_id":51316618133799,"sku":"TP403505","price":399.99,"currency_code":"USD","in_stock":true},{"title":"6.2L \/ Oiled","offer_id":51316618166567,"sku":"TP403506","price":399.99,"currency_code":"USD","in_stock":true},{"title":"6.2L \/ Dry","offer_id":51316618199335,"sku":"TP403507","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0144\/4275\/8230\/files\/tp403504-878c6b7331bce08c614cd7b5e701e882cf6db453.jpg?v=1776799234"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0144\/4275\/8230\/collections\/stillen_red.png?v=1766164041","url":"https:\/\/stillen.com\/collections\/latest-releases\/wheels-and-wheel-accessories.oembed","provider":"STILLEN","version":"1.0","type":"link"}
