Product information "Dr Jekyll & Mr Hyde Exhaust - Bonneville T120"

Dr. Jekill & Mr. Hyde exhaust system with valve control – road-legal and suitable for the Triumph Bonneville

Dr Jekyll & Mr Hyde – arguably the best-known manufacturer of valve-controlled motorcycle exhaust systems with road approval / E-mark (no need for separate registration – just fit it, ride it and enjoy).

!ATTENTION!
Officially, the exhaust is only approved for the Bonneville T120 Euro 5.
However, it also fits Euro 4 & Euro 5+ models as well as the T100 – please feel free to ring us for further information on this.
In addition, an extra OBD adapter is required for models from model year 2026 onwards (see accessories listed in this description)

What does ‘flap control’ mean?

AllJekill & Hyde systems come with an electronically controlled valve in the rear silencer. This allows you to ride your Triumph Bonneville legally in three different sound modes – from pleasantly quiet to a really lovely, deep, bass-heavy sound.
And yes – the sound is truly exceptional for a legal exhaust system. We’ve heard it live on many bikes – simply fantastic.

Black & Chrome – available straight from stock

With this exhaust, you have the choice between chrome-plated stainless steel or black wrinkle-coated (the black coating is a genuine matt finish and very durable).

Fitting instructions & installation at Classicbike-Raisch

Due to the electronic exhaust valve control system, installation is slightly more complex than with a conventional exhaust.
In the download section of this product description, you’ll find the fitting instructions as a PDF. This will give you an overview so you can decide whether you feel confident enough to fit it yourself.

Fitting at Classicbike-Raisch
Don’t feel confident enough to fit it yourself, or simply can’t be bothered?
No problem! Feel free to contact us by phone or email to arrange an installation appointment at our specialist workshop – we’re happy to help!
Installation time: approx. 3–4 hours

Fancy even more sound and performance?

Sound
Is the sound with the flap open still not loud enough for you?
Then an additional X-pipe (catalyse converter replacement) is just the thing for you. This makes the bike a fair bit louder and gives it a much more powerful sound (not legal). The great thing is, though, that the motorbike is still very quiet with the flap closed, so you won’t get into any trouble.
You’ll find the X-pipe amongst the accessories listed below this description.

More power
Would you like to give your Triumph a bit more power – or perhaps even a significant boost?
No problem – have a look at our power kits in various stages.

Accessories

XL-Pipe De-Cat replac CB11934 / RS1

Model: Bonneville T100 / T120

These X-Pipes replace the original Kat-Box / front silencer, which provides a much more pithy sound. In combination with an additional open exhaust system, this results in a really throaty, dull but also loud sound.Also in combination with the original exhaust system you get a much more pithy sound.This is exactly how a 2 cylinder must sound!In addition, the original manifold connecting pipes that go from the cat box to the rear silencers are replaced.Additionally, the X-Pipe and the new manifold pipes result in a significant weight reduction.If you are not only interested in a more beautiful and louder sound, but also in noticeably more power, we advise you to install a large air filter cover and a sports air filter. In addition to that, you have to install a Power Commander and tune the bike on a test bench.The original paneling can be reinstalled, so that the X-Pipe doesn't attract attention.The installation of the X-Pipe / removal of the cat is not legal.

X-Pipe / KAT & Front silencer replacement CB11302 / RS0

These X-Pipes replace the original Cat-Box / front silencer, which provides a much more pithy sound. In combination with an additional open exhaust system you get a really pithy, dull but also loud sound. That's exactly how a 2 cylinder must sound!In addition, there is a weight saving of 1.7 kg compared to the standard catbox. If the X-Pipe is not only about the more beautiful and louder sound, but also about noticeably more power, we advise you to use one of our power kits, in which the X-Pipe is included. Then the whole thing brings also a strongly noticeable performance gain. Click here for our performance kits. The original veneer can be used again, so that the X-Pipe is not optically noticeable. Do NOT fit to Thruxton TFC!
