no sprint hillclimb regs are 105Dbs except where thats over ruled by the venue, but i can only really think of Castle Combe which is 102. Think its summat to do with the fact most venues have planning permission for so many days a year at higher levels, but all the other dates such as track days etc come under normal planning noise restrictions.
Thanks for the suggestions re exh. I was gonna use mild due to it being a bit lighter and bit more ductile than SS. should as you say, take the crackle of the exh note too.
