Best Slip On Exhaust

LeoVince Classic Racer Slip-On Exhaust

LeoVince’s Classic Racer Slip-On exhaust for the Bonneville T120 is all about aesthetics. It sports a retro, Italian design with a loud and crisp exhaust note that demands attention. It’s still a slip-on so don’t expect a ton more power over stock.

This puppy has a unique shape inspired by the cafe racers of years gone by. The lightweight stainless steel build has a striking conical shape and it mounts a bit higher than stock, so it won’t scrape on large bumps in the road.

Speaking of, this exhaust uses AISI 304 stainless steel, which allows it to withstand temperatures of over 1600 F. The surface has a brushed metal finish that just screams quality. We are also huge fans of the embossed manufacturer logo.

But enough about the looks of this exhaust; let’s talk about sound quality. LeoVince went with a double perforated baffle design which gives this slip-on a louder, rowdier exhaust note. It is crisp and high-pitched, without being annoying at full tilt.

If you want a massive performance boost for your Triumph Bonneville T120, you’ll have to look elsewhere. This slip-on doesn’t really add much power to the engine. Still, the lightweight build helps improve the power-weight ratio. And the free-flowing design makes the throttle more responsive.

So, to sum up, LeoVince’s Classic Racer Slip-on has an awesome build, an attractive design, and an appealing exhaust note. It isn’t the most powerful exhaust for the Triumph Bonneville T120, but that’s not the point of this slip-on.

  • AISI 304 stainless steel
  • Mounts higher than stock
  • Does not scrape on any bumps
  • Can withstand temperatures up to 1600 F
  • Lightweight
  • Brushed metal finish
  • Free-flowing design
  • Double perforated baffles
  • Louder exhaust note
  • Improved throttle response
  • Improved power-weight ratio
  • Not the most powerful exhaust

Best Budget

Arrow Pro-Racing Slip-On Exhaust

Arrow’s Pro-Racing slip-on is for the Triumph Bonneville T120 rider who does not compromise. This stainless steel muffler has a sexy exhaust note, a decent boost in power, and tons of style.

The style of this slip-on is right in line with Triumph’s own design language. The conical muffler evokes the look of exhausts from over 50 years ago. But what isn’t retro is the premium materials which are all modern and highly durable. Stainless steel dominates the entire build, keeping this large muffler surprisingly lightweight.

This modern design and construction even extends to the exhaust hanger, which is TIG welded to the muffler itself. This eliminates the need for a separate exhaust hanger piece. You can get a stainless steel end cap to go with the rest of the muffler, though personally we prefer the carbon fiber version for a bit of contrast. And as we all know, carbon fiber adds at least 200 HP to the bike.

Arrow’s racing heritage is pretty apparent from the performance of this exhaust. It has a high-flow design that adds a bit more power to your bike. But even more noticeable is the torque upgrade which allows for faster acceleration, easier low-speed maneuvering, and smoother rolling on the throttle.

Arrow’s sound signature is a loud, race-inspired one that makes the hairs on the back of your neck stand up! It also adds a bit more low-end to the mix, making the sound beefier and more bass-heavy.

  • Lightweight build
  • High quality, durable materials
  • Carbon fibre end cap offered
  • TIG welded construction
  • High-flow exhaust architecture
  • Added power and torque
  • Faster acceleration
  • Smoother throttle response
  • Easier maneuvering at low speed
  • Louder exhaust note
  • Deeper sound
  • Only fits 2016-2020 Bonneville T120 models

Worthy Consideration

Akrapovic Slip-On Exhaust Triumph Bonneville T100 / T120

Akrapovic’s entrant into the race for best Triumph Bonneville T120 exhaust focuses on high performance. It has that awesome Akra sound and easily the most premium build of any exhaust on this list. The design takes some getting used to, though.

When it comes to premium build quality, Akrapovic takes things to the next level. This exhaust uses a full titanium muffler, which saves almost 4 lbs over the stock weight of the Triumph Bonneville T120.

Pairing that weight loss with improved power and performance gives you a noticeably faster, more agile bike overall. In fact, you can expect up to 5 extra horsepower, and 5 nm of torque with this exhaust and a nice tune.

Akrapovic’s unique sound profile is just as appealing here as it is on their other exhausts. It is louder, yes, but also focuses on being heavier and more imposing. Still, it also has that high-pitched quality at high RPMs that Akrapovic pipes are known for.

The design is a bit divisive, however. We are huge fans of the modern, angular look, but some Triumph Bonneville T120 riders might think it doesn’t fit their retro bike. We can confirm that it isn’t nearly as awkward as you might think, and actually looks pretty slick in person.

All said and done, the Akra is a performance pipe first and foremost. It sounds amazing, and has a lightweight build made from the most premium materials. Sure, the design isn’t for everyone, but we think the compromise is well worth it.

  • Titanium build
  • Lightweight
  • Sleek and modern design
  • Bass-heavy sound
  • Louder than stock
  • Best performance of any T100 exhaust
  • 2 hp and 5 nm boost
  • Faster acceleration
  • Improved performance throughout the rev range
  • Made specifically for the Triumph Bonneville T100
  • No custom fab job needed
  • The most expensive exhaust on this list
