Help 87 kdx200 interchangeable expansion chamber??

Nov 10, 2019
I was just wondering if anyone in the world knew if there was any interchangeable expansion chamber that would fit on an 87 kdx200? I know that the 86-88s will but I need to know if there is any ones that would fit it? Without that much of modifications. Go to google type in 87 kdx200 exhaust and scroll down to the 2nd video please. It's a video that shows an fmf fatty on an 87 kdx200 that the guy only had to do a little bit of mods to make it fit
