Exhaust connection bolt size
Does anyone know the size of the bolts for the upper and lower connection of a downpipe (header to downpipe, ubend (delete) to catback system)? I am replacing the downpipe soon and I want to pick up some extra bolts in case I break them. I would assume they're relatively standard and I won't have to go to the dealer to get them?
