British Customs Sleeper 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 Exhaust System for the Triumph Bonneville.

Precision-manufactured from 14-gauge stainless steel, the Sleeper Exhaust was built for performance and durability. A mechanical louver baffle maintains optimal backpressure increasing exhaust flow. The true beauty of Sleeper 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 System is engineered for trouble-free fit and outstanding performance. The Sleeper 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. The British Customs Sleeper Exhaust is available in high-polish showroom finish or a sinister black ceramic coating.
