Best Exhaust for Triumph Bonneville T100

The best exhaust for Triumph Bonneville T100 riders should make the bike sound more alive without overwhelming its light, classic personality. The T100 is often used for commuting, back-road riding and relaxed weekend trips, so sound quality and fitment matter more than maximum volume.

What Makes a Good Bonneville T100 Exhaust?

A good T100 exhaust fits cleanly, keeps heat away from the rider, looks period-correct and gives the parallel twin a fuller tone. Many riders prefer slip-ons because they are simpler, lighter and less likely to disturb the whole setup.

• Slip-on mufflers: best first upgrade for most T100 owners.
• Classic peashooter design: keeps the stock-inspired Bonneville look.
• Black finish: suits custom or darker builds.
• Chrome or stainless: fits classic and polished builds.

T100 Exhaust Sound

The ideal T100 exhaust has a deeper idle, a clear twin-cylinder pulse and controlled volume at cruising speed. If you ride in town early in the morning or use the bike daily, avoid the loudest open-pipe setup.

T100 vs T120 Exhaust Fitment

T100 and T120 exhaust pages often get mixed together, but the bikes can have different engine, frame, bracket and emissions details depending on model year. Always buy by exact year and model, not just by visual similarity.

Will a T100 Exhaust Need Tuning?

Most mild slip-on upgrades are designed for stock fueling, but full systems or cat-delete setups may require ECU adaptation or a proper tune. If the bike pops heavily, runs poorly or feels flat after installation, tuning should be checked.
