Product Details

British Customs Sleeper Pro Silencers for Triumph Bonneville T100

Just because you want some extra grunt from your Hinckley Twin, doesn’t mean you have to announce it to the world. To keep you flying even faster under the radar, British Customs has developed a Sleeper Pro Exhaust System for the Triumph Bonneville.

Precision-manufactured from 14-gauge stainless steel, the Sleeper Pro Exhaust was built for performance and durability. A mechanical louver baffle maintains optimal backpressure increasing exhaust flow. The true beauty of Sleeper Pro system is that it accomplishes this without making you sound like a hooligan in the process and delivers a retro look that oozes cool.

The fit and finish are seamless, with all welds carefully ground out before finish-ing. British Customs is setting the standard for aftermarket exhaust for Triumph motorcycles. Like all British Customs designs, the Sleeper Pro System is engineered for trouble-free fit and outstanding performance. The Sleeper Pro System will fit both the EFI and non-EFI Bonneville.

Stainless steel construction ensures superior quality over traditional chromed steel, delivering enhanced corrosion and pitting resistance. Polished stainless is also easier to maintain than chrome, which can be quickly ruined once the surface is scratched or dinged. 


  • Includes side stand and center stand brackets
  • Stainless steel components: no pitting, flaking or rusting
  • Mechanical louver baffle

Note: Check last six digits of VIN # for proper fitment.

BC Sleepers on 2012 T100 Bonneville
I recently purchased the B/C sleepers for my 2012 Bonneville T100. The sound improvement over stock pipes is amazing. My opinion is a bit skewed though as I have never heard a different set of exhaust on a T100. I did however watch a lot of videos on YouTube prior to purchasing, and if there is a better sound quality then what these B/C Sleepers produce, I'd be amazed. They were extremely easy to put on and are considerably lighter then the stock exhaust. I would recommend these to any triumph twin owner who's looking for a little more power and an exhaust system that gets you noticed but is not obnoxiously loud.

Perfect Pipes for the Bonneville
The previous reviewer was spot on. The sound improvement over stock pipes is fantastic. Installation was extremely easy. If you're a Bonneville owner seeking a louder rumble (but overly obnoxious) and a little more power, then buy a set of BC Sleepers.
