I have a 4 into 2 exhaust with fabricated shorty mufflers to fit a cb350f or possibly 400f. I do not know the manufacturer. Exhaust is very solid with no holes and very little rust, just some chrome missing on inside of pipe from previous owner possible spilling something on it. You may have to mod you side stand spring on a 350f to fit. I did have it installed on my 350 but never used it. Asking $80. Thanks
