I ordered a 74 cb750 exhaust that looked like a spigot style not the stud style for my 76 cb750k and when they showed up they have a 1/2" collar on them not a flanged end and not a flare to fit my spigots and there doesnt seem to be a flange inside the pipe. I'm thinking they are for a smaller size bike b/c the id of my header spigot seems to be the same id as the pipes but the collar is 1/4" thick. Anyhow I'm thinking of running a reducer from my pipes to my header since they are the same ID I think its 1 1/4". The seller didnt specify what model they were but the collar in the picture appeared to be the flange to fit the spigots but I got this damn collar on there that I've never seen on either types of cb exhaust. any help is appreciated in figuring out this crap
