THE LOOK
Designed for the liquid-cooled Triumph family. Thruxton, Thruxton R, Bonneville T120, Bonneville T120 Black, and the Street Twin/Street Cup. Smaller and more compact than OEM or our Dominator series. The compact cone/reverse cone design bolts directly into place on your stock headers and mounting positions. With only a 15" overall length, the exhaust will end well in front of the rear axle and chain adjuster, making routine rear wheel maintenance much easier.
Our Shorty Performer exhaust has a maximum diameter of 3.75" and features a large 2" reverse cone opening. A lot of mufflers with large outlets have a "hollow" sound, but with our unique double-step, dimpled perforated core, you get a tight, solid, exhaust tone!
THE FIT
Fits the original equipment Triumph headers and catalytic convertor. These mufflers should also fit aftermarket headers (or X-pipe/Cat-Delete) that are designed to reuse and guaranteed to fit the OEM mufflers.
The muffler mounting bracket attaches to the backside of the stock passenger foot peg support, using an included spacer that replaces the stock rubber rear peg insert. These mufflers can be used with either stock passenger pegs, or with foot peg block off kits. Our muffler kit includes clamps, sealant, and spacers - everything you should need to complete your installation.
If you retain the stock catalytic convertor, no retuning should be required.
THE SOUND
Even with the minimal size of these mufflers, you don't get an excessively loud sound when you retain the stock catalytic converter. They are slightly louder and with a little more aggressive than our Dominator Sport mufflers, when fitted to the same motorcycle.
IF YOU REPLACE THE STOCK CATALYTIC CONVERTER WITH A "CAT DELETE DEVICE", THE EXHAUST WILL BE MUCH LOUDER.
