Back when I got this basketcase the mufflers had holes rusted all through them. So I just chopped them off. Its an '81 with stock headpipes. Now that the bike is running, I'm wondering if there is a simple and cheap way to buy some mufflers and attach them to these headers??? If so what size do I need and how would I go about attaching them?? Sorry if this is a dumb question, I'm clueless about this stuff. I'm open to any simple and cheap solutions. Thanks!!
