TEC DUELLER 2-2 Big Bore Exhaust System – Street Twin 900, Street Cup 900, T100, T120
£416.66 – £428.33
Awesome sound, more responsive.
Listen to our sound-test video below!
Designed and manufactured by us in 304 stainless 45mm tube.
The Big Bore pipes make your bike more responsive whilst saving considerable weight over the stock headers.
Completely bypasses Triumph’s CAT, de-restricting airflow from the engine and releasing a deeper sound.
The TEC marked silencers come supplied with TWO different sets of baffles: ‘Big-Bore’ baffles & ‘High-Flow’ baffles. Easy to swap out to modify your sound.
Additional 10-Hole quiet baffles can be supplied if chosen in the drop-down menu.
IMPORTANT – You MUST tell us on the notes of your order (at checkout) if your bike has a centre stand installed. We will then ship it with the alternative fitting kit.
PLEASE NOTE – On these models, these headers & silencers can only be fitted as a full system due to the specified models using a different frame. It is not possible to fit only the headers, or only the silencers. Similar slip-on silencers are available for the Street Twin/Cup only (please see our other listings)
Gaskets and fitting instructions 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.
Fantastic new look to my 2021 T120
Great sound with the choice of baffles and more responsive
Awesome exhaust system, makes the bike sound like a proper bike, easy to install, more responsive on the throttle.
Well worth the price.
Arrived 2 days after i purchased them, easy and simple to fit on the bike.
Removing the cat was a pain but so worth it to have these exhausts on the bike.
Sounds like a proper bike now and is alot more responsive on the throttle.
Amazing quailty, excellent details on the welds and the heat shields finish it off nicely.
