    The GP Exhaust is a truly handcrafted muffler made by some of today’s most skilled technicians. Step by step, each muffler is slowly, meticulously rolled and TIG welded from 100% stainless steel to create a muffler that evokes the golden era of motorcycle racing. GP-style exhaust usually only comes as part of a full exhaust system, requiring you to completely remove your old exhaust pipes and redo your air intakes in order to get them working. For riders seeking to give their modern classic a vintage road race look and sound, the GP Exhaust is the highest quality performance solution available.


    • Handmade exhaust by master technicians
    • 100% stainless steel construction
    • 2.5lbs per exhaust
    • Repackable stainless steel mesh perf core baffle for optimal backpressure
    • Vintage road race looks and sound
    • Rubber mounted bracket for increased durability and easy installation
    • Proudly made in the USA

    Add on the Performance Essential Pack to get the most out of your Triumph

    If you have installed or plan on purchasing one of our Slip On Exhausts, you should consider adding our Performance Essentials option to your order. Depending on the model you are working on, these Performance Essentials will vary. 

    For Air Cooled Triumphs (Pre 2016 mostly), we offer our Air Box Removal Kit and Air Injection Removal Kit. When combined with a Slip On Exhaust, these products will enable your bike to get the proper intake needed to best support a free flowing aftermarket Exhaust and keep the engine running at the right temperature.

    Q: Will these fit my model?
    A: In the drop down menu, you will see an option to choose your model

      Q: Do I need to remap or change the tune after I install these pipes?
      A: For Liquid-cooled models, a remap is not required due to the self-learning system in the ECU unless an X-Pipe is installed although we do recommend using a Power Commander to get the best performance out of your machine
