TEC DUELLER 2-2 Big Bore Exhaust System – Speed Twin 1200 and Thruxton 1200 models

Impressive sound, heightened responsiveness.

Take a listen to our sound-test video below.

Crafted and engineered by us using 304 stainless 45mm tube, these Big Bore pipes offer both enhanced performance and significant weight reduction compared to stock headers.

By bypassing Triumph’s CAT, these pipes allow for unrestricted airflow from the engine, resulting in a deeper exhaust note.

Supplied with TWO sets of baffles: ‘Straight through’ and ‘6-hole’ baffles, making it effortless to customize your sound.

Front pipes & Silencers are also available separately and can be mixed & matched with OEM parts – please refer to our other listings.

Gaskets and fitting instructions are included for a seamless installation experience.

NOTE – On pre-2020 models, you can leave the Cat unit in place (but not connected) this allows a much quicker and easier fitting. Otherwise, the left lower frame rail needs to be loosened to allow the Cat to be removed.  We have a YouTube video showing how to remove the cat unit.

From 2021 Triumph has introduced new Euro 5 models and have started phasing in anti-tamper, welded on rear link pipes to the Cat unit on some models. If this is the case on your bike the Cat unit will have to be removed before installing the system.

THIS SYSTEM IS NOT TUV APPROVED OR E-MARKED. As this system has no catalytic converter, it cannot be marked TUV approved. Silencers are laser marked EU noise legal only.
