The 2007-2013 Toyota Tundra Exhaust
Currently, we offer the off-road dump version for the 2007-2013 Tundra, perfect for those who demand the best in off-road performance. But that’s not all—keep an eye out for our over-axle version coming soon.
Why Choose STILLEN’s Cat-Back Exhaust?
American Designed and Manufactured: Proudly made in the USA, our exhaust systems meet the highest standards of quality and craftsmanship.
Enhanced Performance: Feel the surge in horsepower, torque, and overall engine performance with optimized airflow for improved throttle response and acceleration.
Signature STILLEN Sound: Revel in the deep, throaty tone that only a STILLEN exhaust can deliver, making your Tundra roar with authority.

Durability and Reliability: Constructed from high-quality materials, our exhaust systems are built to withstand the demands of daily driving and off-road excursions.
Easy Installation: With a seamless fit and simple installation process, you can upgrade your exhaust system with basic hand tools and hit the road in no time.
No Drone: Stillen tested this system with a various array of our mufflers until we found the perfect note without any drone. Moderate sound under cruising, with a boisterous grumble under full throttle. No need to turn up the volume to hear your music or speak any louder to continue the conversation. The perfect sound to turn heads without your neighbors hating you at 6 AM.

One of the best features of our new exhaust systems is their interchangeability. Easily swap between the full over-axle version and the shorty dump version using simple hand tools, giving you the flexibility to adapt your Tundra to different driving conditions and personal preferences.

At STILLEN, we’re thrilled to unveil our latest innovation: the STILLEN Cat-back Exhaust System designed to fit the 2011-2024 Ram 1500 5.7L. Crafted with precision and passion, this exhaust system is tailored for enthusiasts who crave both performance and aesthetics.
Unleash the Power:
Our cat-back exhaust system is engineered to optimize your truck’s performance. By reducing backpressure and enhancing airflow, it boosts torque and horsepower, giving your Ram 1500 the power it deserves. Feel the difference in every acceleration as your truck roars to life with newfound vigor.
Lightweight and Durable Construction:
Constructed from premium stainless steel, our exhaust system is built to withstand the rigors of the road. Not only does this material ensure durability, but it also contributes to a weight reduction of 5 pounds compared to the factory exhaust, even with a larger diameter. Lighter weight means improved agility and efficiency for your Ram 1500.
In our research of the market, we found that many exhaust systems lack adjustability, leaving customers with limited options for customization. To address this issue, we’ve added an additional adjustment point just before the tips. This innovative feature allows customers to fine-tune the exhaust to their exact style or bumper, even aftermarket, ensuring a perfect fit every time.

Are you looking to upgrade your vehicle’s exhaust system for a boost in performance and a distinctive sound? Let’s delve into the world of aftermarket exhausts, specifically comparing axle back and cat back systems to help you make an informed decision.
Axle back exhaust systems offer a balance between performance, style, and sound enhancement. They are a cost-effective option compared to cat back systems. By replacing the exhaust components from the rear axle to the tailpipe, axle back systems provide a noticeable change in exhaust tone and aesthetics.
Improved Sound: Experience a richer and more aggressive exhaust note without breaking the bank.
Enhanced Style: Many manufacturers offer customization options, including various finishing tips such as carbon fiber, blue burnt tips, or polished stainless steel.
For those seeking maximum performance gains, cat back exhaust systems are the go-to choice. Unlike axle back systems, cat back upgrades replace components from the catalytic converters to the tailpipe, eliminating restrictive elements like crush bands and mufflers.
Optimized Performance: By employing mandrel bent tubing and less restrictive mufflers, cat back systems allow exhaust gases to exit more efficiently, resulting in increased power.
Comprehensive Upgrade: Cat back systems provide a holistic enhancement to the entire exhaust system, ensuring a consistent boost in performance.
Customization Options:
One of the exciting aspects of upgrading your exhaust system is the ability to customize its appearance. Manufacturers offer various finishing tips, allowing you to choose between carbon fiber, blue burnt tips, polished stainless steel, or even unique finishes like black ceramic coating.
In conclusion, whether you opt for an axle back or a cat back exhaust system depends on your priorities. If you’re looking for a cost-effective way to enhance sound and style, an axle back system might be the ideal choice. However, if maximizing performance gains is your primary goal, investing in a cat back system will provide a comprehensive upgrade for your vehicle’s exhaust.
Upgrade your driving experience, unleash the full potential of your vehicle, and make a statement on the road with a carefully chosen aftermarket exhaust system.
STILLEN is thrilled to announce a significant development for automotive enthusiasts looking to boost their Nissan and Infiniti models’ performance. Our renowned Gen 2 and Gen 3 Stillen Intakes, known for delivering unparalleled power and precision, now come with even more accessible pricing in 2024.
Unleashing the Power: Gen 2 and Gen 3 Stillen Intakes
The Gen 2 and Gen 3 Stillen Intakes have been game-changers in the automotive performance realm, and their compatibility extends to various Nissan and Infiniti models, including the G37, 350Z, 370Z, and Q50. Today, we shine a spotlight on the Nissan 370Z Gen-3 Air Intake and its exceptional features, while also introducing the Gen 2 Stillen Intakes.
Key Features of the Gen 2 and Gen 3 Stillen Intakes:
Ultra Long Mandrel Bent Polished Aluminum Intake Tubes
Oil-Free and Low Restriction Design
Increased Throttle Performance and Horsepower
Easy to Clean with No Need to Re-Oil
Benefits That Speak Volumes:
CARB EXEMPT EO# D436-22 (2009-2016 ONLY)
Impressive 17.5 RWHP / 13 WTQ Gain for Enhanced Acceleration* (Gen 3 – 370Z Only)
Designed and Manufactured at STILLEN HQ, Inspected Multiple Times for Quality and Fit
Fits Various Models, including 370Z and 370Z Nismo (Nismo models may require slight modification)
Why Gen 2 and Gen 3 STILLEN Intakes?
STILLEN has been at the forefront of high-performance cold air intakes, and our journey with the Nissan Z34 and Infiniti VQ37 equipped cars has been nothing short of groundbreaking. We started with the Gen 1 Cold Air Intake, offering a small gain in power and a captivating sound enhancement. The Gen 2 Long Tube Intake refined the design and power output, becoming one of our best-selling air intake kits.
The skeptics fueled our determination to push the boundaries further, leading to the development of the Generation 3 Ultra Long Tube Cold Air Intake Kit for the Nissan 370Z. At STILLEN, all our products are designed and manufactured in-house, giving us the ability to test numerous configurations and fine-tune our designs until we achieve the desired results.
Unprecedented Power Gains [Gen 3]:
Our R&D team tirelessly tested over 50 variations before perfecting the Gen 3 design for the VQ37HR engine. The result? A dyno-proven 17.5 Horsepower (WHP) and 13 ft/lb (WTQ) gains on the 370Z with STOCK ECU TUNE. This achievement is unparalleled among performance intakes for non-turbo/non-SC’d cars.
Optimized Design for Maximum Performance:
Both the Gen 2 and Gen 3 intakes boast updated designs with integrated systems of variable diameter tubing and steps, maximizing air velocity. The strategically placed large STILLEN air filters ensure exposure to the coldest-possible incoming air, enhancing performance.
Easy Installation for Maximum Impact:
While the power gains are extraordinary, we’ve ensured that the installation process is straightforward. While removal of the front fascia clip and slightly enlarging the holes through the front core support is recommended for optimal results, it’s worth noting that the bumper removal process is quite manageable with basic hand tools.

To start with, 2.5-inch stainless steel tube is cut in bundles using the STILLEN hydraulic CNC controlled band saw. From the saw the tubes are processed on our CNC Mandrel Tube Benders. Every tube coming off the bender is verified in our proprietary bend check fixtures to ensure each tube meets our specifications.
CNC Milling Machine and STILLEN X Pipe Fixture
The STILLEN X pipe has been engineered for optimum performance and exhaust gas flow. To achieve the best performance possible the X pipe tubes are loaded into the CNC milling machine and are precision machined for perfect fitment into the weld fixture.
Once the machining process is finished the machined tubes along with the weld fixture are taken to the production welding booths where our craftsmen tig weld the tubes and braces to form a single X pipe.
When merging dual 2.5” exhaust tubes into a single tube, the equivalent size tube required is more than 4 inches in diameter. Because we cannot fit a 4-inch tube through the chassis and a true dual 2.5” exhaust did not sound good on this platform. We chose to merge the two banks for the best sound, but to do so in a way that allowed for optimal exhaust gas flow without causing a restriction.
STILLEN Mufflers
To assemble the mufflers our production team begins by assembling the perforated tube inner core. Then form the end caps for the body of the muffler. The inner core and one side of the muffler is tack welded together then the muffler goes back to assembly to have the high temperature ceramic wool inserted.
Once completed the mufflers go back to welding. The outer cap is tacked back together. This is the only time where the exhaust system or any of its components leaves the STILLEN facility. The mufflers are sent to an outside processor for polishing before they’re finished welding.
STILLEN Proprietary Rotational Welding Positioner
After the mufflers return from polishing, it is placed on our proprietary rotational welding positioner. Our engineering team created this positioner so that our welders could accurately control the speed. Also the orientation of the mufflers to give a precision tig welded finish. The mufflers are purposely left with a fantastic “burn” finish to show the tig welded craftsmanship.
Final Welding and Assembly
Now we enter final welding and assembly. Every single exhaust system goes through our pre-assembled weld fixtures. These weld fixtures located all of the key components. The weld fixtures also align everything to ensure perfect, repeatable fitment on all of the various components.
Since 1986 STILLEN has been a leader in exhaust system manufacturing. STILLEN is dedicated to manufacture all our exhaust systems in the United States of America.
