Today, my "street triple 675 " stickers arrived. So I could finish the job as I visualized it in my head.
With the bad weather and all that , I did not really do a lot of miles on the bike, but I did test the carbon folie during 2 trips of around 45 km each on different trajects, some high speed highway, some backroads, a little idling inbetween , so the bike was softly ticking when I shut the engine and all went well. The carbon vinyl did not melt. Lets see what summertemperatures will do.
Anyway , The first 7cm ( not so big) of the OEM exhaust is the reflection part and that gets really hot. ( maybe to hot in the future?), The rest is the absorbtion part and doesn't get that hot. So lets see if the 3M Carbon vinyl on my OEM's will stand the test of time and heatcycles
It may be that the TOR exhausts , that Mpact used, are flow thrue and only have a absorbtion part?? ( that explains their deeper rumble) and just get less hot on the entry pipe?
