Go North East’s preferred contractor for the Euro 6 exhaust modifications is Eminox, who don’t have any options to upgrade Streetlites from Euro 5 to Euro 6.
There’s a possibility of a whole engine conversion, which I think (stand to be corrected) is what Stagecoach have done on MANviro 300s 24101-15, but this is presumably a lot more costly.
