Upgrade your Triumph Thruxton 900 (2004-2016) with the Predator Pro Slip-On Exhaust by British Customs, a top choice for those seeking a substantial upgrade in performance, sound, and style. Priced at $729.95, this premium exhaust includes FREE SHIPPING and earns you 7299 Rider Rewards points with every purchase.

The Predator Exhaust was first created in 2004 when British Customs sought to develop a modern exhaust that captured a vintage-inspired style and sound. The reverse cone exhaust shape, used since the 1960s, has been rigorously tested for its unique ability to improve performance by efficiently expelling exhaust gases. This classic design, preserved for both its aesthetic appeal and performance benefits, combines with a louvered baffle core to produce the distinctive vintage Triumph sound that perfectly complements the retro look of the Thruxton 900.

After 12 years of redesigning, track testing, and listening to customer feedback on the original Predator Exhaust, the updated Predator Pro was released in 2017. While maintaining the same iconic look and sound, the new version integrates the louvered baffle design within the exhaust for increased durability and a rubber-mounted bracket to isolate engine vibrations, improving rider comfort and reducing bracket fatigue.

The Predator Pro Slip-On Exhaust is fabricated using 100% 304 Stainless Steel, offering exceptional durability, corrosion resistance, and a seamless-smooth finish with TIG welding. Its polished, mirror-like appearance adds a sleek, refined touch to your Thruxton’s vintage aesthetic. The carbon fiber end cap provides a modern edge to its incredibly lightweight construction.

This easy-to-install exhaust system offers a direct bolt-on upgrade, replacing stock mufflers without requiring additional modifications. Its proprietary mechanical louvered baffle design enhances airflow, boosting horsepower and torque for a smoother throttle response and improved performance. The updated baffle design is also compatible with a dB killer, reducing the exhaust tone by 2-3 decibels without losing the aggressive, deep, throaty sound that the Thruxton is known for.

Crafted in Gardena, CA, the Predator Pro Slip-On Exhaust ensures longevity and easy maintenance with its stainless steel construction, making it resistant to rust even in harsh weather. This exhaust delivers a perfect balance of sound, performance, and style, making it a must-have upgrade for Thruxton 900 owners looking to enhance their ride.

Shop now and experience the substantial upgrade provided by the Predator Pro Slip-On Exhaust, offering an ideal combination of vintage-inspired design, improved performance, and easy installation for your Thruxton 900.

If you're looking to unleash the full potential of your Triumph Modern Classic, the British Customs air box removal kit is a must-have. This simple upgrade allows you to ditch the restrictive factory air box in favor of two high-flow K&N air filters, for a significant boost in power and performance.

The British Customs Airbox Removal Kit

• _ _

How does removing the air box increase performance? The OEM air box routes air intake through the stock snorkel (located underneath the left-hand side cover), which then flows through the restricted air box to the carburetors or throttle bodies. By removing the stock air box and installing two high-flow K&N filters directly onto the carburetors or throttle bodies, you'll ensure maximum airflow for optimal power and performance.

Whether you're hitting the open road or the race track, this easy upgrade will help you get the most out of your Triumph. So don't wait - make the switch today and experience the difference!

FEATURES

• Increased airflow means more horsepower
• Improved throttle response
• Designed to work with or without side covers

JET KIT INCLUDES

• 135 Main Jet (Qty 2)
