Probably a Longshot, bit I'm looking for a4 into 1 exhaust for my project 1980 cb750f ss. Mine has the stock 4 into 2 that are in good shape except the left side muffler has been welded a bunch, and both sides have had the baffles removed. If I have to, I'll go the delkevic route, but wanted to see what's out there. I haven't been able to find any pics of aftermarket slip-on mufflers for the 4 into 2 and don't want to spend a couple hundred on that route, only to scrap it and go 4 into 1 anyway.
