Right next to one of our first exhaust designs being the Predator's, the Sleeper design was made to look like traditional peashooters yet with a punch, rigid design for durability & a nice growl hence the name, "Sleeper".

Updated in 2017, the redesigned pipe retained all that made the original popular while updating the design to benefit from over a decade of real world use.

  • 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 
  • Enhanced sound, performance & looks

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

Other than some muddled instructions (which, at least in the early version, showed the pipes mounted upside down) I am very happy indeed with these. They look more classic, and have a bit more of the traditional Triumph brap to them. Not super loud, but a bit louder, and overall a better sound I think.

After much research and watching/reading reviews I decided to purchase the Sleeper Pros. They shipped amazingly fast and the packaging was great. After fitting I cranked the T120 up and immediately smiled. A deeper more guttural note emitted at idle. Upon riding the difference really kicked in. Fantastic note especially when you hit 3000 revs and above - it turns the Bonny into a snarling beast. I am SO happy I bought these. Thank you

I have done quite a few mods to my 2015 Bonneville T100, but by far and away the single best thing I've done was to add the Sleeper Pros. Their tone is sublime! Added a few more HP to boot. What's not to like??
