Hi guys. I am working on a 74 CB550 that has a 4 into 2 exhaust. I’m not sure if it’s aftermarket but the mufflers are rusted out. It looks like it could be an old MAC system or at least MAC mufflers. I saw these on eBay and they look just like the current rusted out mufflers. However, they are for the 79-82 CB750. Does anyone know if these would work (ready assuming I will need a bracket to attach at the foot peg). The head pipes are in great shape, BTW. THANKS
