Purchasing Exhaust Pipes for your Vintage Brit Bike: Do You Need Spigots?

When deciding which exhaust system is right for your bike it is important to know what head your motor has. Never assume that there is such a thing as stock when it comes to a British bike. Some 1970s heads have spigots while others do not; some spigots are threaded into the head, some are pressed. This is an easy error to correct by looking at your head and, by all means, remove your old headers to see exactly what you have and what you want.
