Bring out the timeless sound of your Triumph motorcycle with the Predator Pro Slip-On Exhaust, designed to produce an iconic exhaust note reminiscent of the '60s and '70s Triumphs. This exhaust system elevates the sound of your exhaust, improves performance, and smooths throttle response. Perfect for riders who appreciate the traditional Triumph sound and aesthetic.

The Shorty Predator Exhaust was originally designed in 2004, the reverse megaphone design pays tribute to the original exhaust found on many of the early custom triumphs. The goal of the Predator was to replicate the sound and style of the vintage reverse megaphones while increasing the performance of your Triumph Motorcycle. Updated in 2017, the redesigned pipe retained all that made the original popular while updating the design to benefit from 12 years of real world use.

Features:

• Over a decade of R&D, from track racing to everyday riding
• Shorty design results in 6" shorter than standard Predator & slightly louder
• 304 Stainless Steel Construction, TIG welded & grounded off to a seamless-smooth finish here in California, USA
• Proprietary mechanical baffle design integrating the baffle into the housing of the Predator Pro body, increasing rigidity for increased durability
• Bolt-on design

Note: Liquid Cooled Bonneville T100/T120 prices are higher compared to other models due to exhaust gaskets that are included for installation.

As British Customs has grown as a company we’re always finding ways to keep pushing the boundaries and expand the capabilities of the parts we make. After years of testing and refining the design of the original Predator Exhaust since its release in 2004, we wanted to create a fresh new version of it that was not only lighter and increased performance but also introduced carbon fiber into the predator exhaust line.

At first glance the Predator Carbon definitely has an updated and modern look, but there’s more to its upgraded design than what meets the eye. Built with lightweight 20 gauge instead of 18 gauge 304 stainless steel and swapping out the Louvered Baffle Core for our higher flowing and lighter perforated Race Baffle Core, it is the lightest slip-on exhaust we’ve created yet. At the tip the carbon fiber end cap makes it fully serviceable and gives the exhaust a unique look while offering even more savings in weight.

Durable and corrosion resistant, this exhaust is available in 3.5” and 4” sizes with your choice of a polished or brushed finish. From time to time we also release limited runs of our Special Edition black color. You can sign up for our newsletter to stay up to date on special edition releases.

FEATURES

• Rolled by hand from 20 gauge 304 Stainless Steel
• TIG welded then finished in brush or mirror polish
• Carbon Fiber End Cap design
• Perforated Race Core baffle
• Lightest exhaust in our offering - 4lbs below the stock exhaust, per side on a stock Speed Twin

With a handcrafted look that takes its inspiration from Moto GP exhausts seen on the track,

British Customs’ GP Slip On Exhaust is a unique choice for your Triumph, providing an updated alternative to the typical classic style exhausts available for Triumphs while delivering real performance benefits.

The GP exhaust is the lightest British Customs stainless steel exhaust system, manufactured from lighter 20 gauge stainless steel (rather than 18 gauge used in our other exhausts) and updated internally with our new race core instead of the heavier, louvered cores used in the Predator Pro and Sleeper Pro Slip On Exhausts. The perforated baffle core is wrapped in stainless steel packing and allows for increased air flow, less weight, and a higher pitch performance exhaust sound.

Each segment of this stainless steel exhaust system is rolled, hand shaped, fitted, and brushed in Gardena CA, manufactured with care by our expert craftsmen who leave the welds exposed to preserve and feature the craftsmanship poured into it. Design features like rubber isolated exhaust hangers reduce engine vibration and bracket fatigue, and each exhaust is finished with a riveted stainless steel end cap making the exhaust serviceable if you send it back to us for repacking.

Features

• One of the first & original "GP" designs for Triumph modern classic models
• 100% Stainless Steel Construction
• Light - weighs approximately 2.65 lbs per muffler
• Bolt-on installation using factory mounting points
• Perforated baffle core for higher engine flow, weight savings, and race sound
• Rubber isolated exhaust hanger to reduce bracket fatigue and engine vibration. 
• Exposed TIG welds for a handcrafted look

NOTES: The GP Slip On Exhaust will not work with a center stand.

Liquid Cooled Bonneville T100/T120 prices are higher compared to other models due to 2x gaskets that are included for installation.
