Got an early Baywindow bus 68-71 that uses a Mustache bar to mount the engine? If so this is the exhaust you need to clear that mount and allow you to run either J tubes or keep your heater boxes. These kits come with the Flanged header, hidden tip muffler and you can add a set of flanged J tubes if you need them or keep your heater boxes. These kits are full stainless steel, with the V band connector and are available in raw or fully polished stainless steel for a show quality finish as well as Black Cerekote!
