I have a set of hedman headers for my 69 chevelle with a 454 that are full length headers and are hooked up to the rest of the exhaust. I just bought the mid-length ceramic Patriot headers for clearance. I do not have the luxury of welding right now so are there any pipes that will hook up to the mid length headers and to the rest of my current setup of exhaust? Part numbers would be very helpful and all I can find is the pipes that hook up to stock manifolds, any suggestions? Thanks
