Tec 2 Into 1

moving on from my previous inconclusive thread, I’ve now bought a TEC 2 into 1 system from eBay. The original plan was to reuse some of the pipework (particularly the junction) for refurbishing vibration damage on my Sportster flat track bike (it was VERY cheap...) but I’m wondering about fitting it to the Triumph (2013 T100) to replace the offensively loud Dunstalls.

That, or use the front pipes plus a Supertrapp on the Triumph. I know Supertrapps and have a selection of plates and endcaps available - has anyone tried this and if so, what was the outcome?
