to be honest jester i dont want pipes to over the legal limit tried open tors but thought they were a bit loud 91db,saying that as we know legal limit is 80db.This is the question would you say you tridents with legal inserts in are quieter than the triumph off road pipes if they are i think i need to do some grovelling to peter sorrell,and hope that £250 deal is still on.Its a lot of money to save up and best to purchase the right ones first time around.Is the bsau mark visible when baffles fitted?.
