Absolutely yes, and offer standard sized nuts and bolts in stainless too for other applications in an easy to navigate website with fair postal charges, it's the classic and long term owner who you are your potential customers i daresay, i doubt many owners of white goods car even know they have an exhaust till it falls off.

I liked the old BMC A and B series engines you never had trouble getting the brass manifold bolts off even if you had to hammer an undersized socket on, i hate undoing the down pipe on a modern car knowing there's a good chance of a snapped rusted manifold bolt headache.
