What is the typical cost a guy would expect to spend to have dual exhaust put on his 1956 2nd Series Chevy Shortbox? My engine has the exhaust manifolds, but nothing else. And can a guy just forget about adding the exhaust manifold heat riser valve if it won't be used in the winter time? Thanks for the help.
