Big Bore Front Pipes – Speed Twin 1200 and Thruxton 1200 models

The Big Bore pipes make your bike more responsive whilst saving considerable weight over the stock headers.

Designed and manufactured by us in 304 stainless 45mm tube.

Completely bypasses Triumph’s CAT, de-restricting airflow from the engine and releasing a deeper sound.

Can be mixed & matched with any silencers (including OE silencers) that fit stock front pipes.

Gaskets included.

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.
