This is exhaust is unique to Total Triumph, and designed in house to replicate the 'Short Slash Cut' pipes fitted on the Scrambler 1200 in recent Guy Martin TV Programme, and the upcoming James Bond Film - No Time to Die.
This slip on silencer is supported on original exhaust mounts, and saves over 5 kg by removing the OEM silencer. As expected the volume increases as they are effectively straight through (you could install universal 42mm baffles if required) so sound best with the OEM Catalytic converter still in place.
Update 04/02 - This exhaust now includes dual baffles fitted as standard. This is mainly for the 2022 onwards models, which no longer have the CAT in the header pipes so the baffles ensure noise levels are acceptable, but also that enough back pressure remains to maintain correct performance. Offering a huge 5+ kg weight saving on the standard silencer.
