Hi all, removed cans from my 1098 streetfighter with no problems, now i have put them back i have notice that there is smoke coming out of the top can and where it fits on to the top of the exhaust. Anything i can do to get a better seal and stop the smoke, also will this fail M.O.T
Do not use silicon sealant on exhaust joins if you have lamda/closed loop fuel systems, the sealant burns and coats the sensors in silicon rendering them useless.
