    250x 350x conversion exhaust ?

    picked up a 250x the other day that was set up with the 350x motor in it . motor was out of it and does look like my 350x motor . i have a 86 350x so i figured i would keep the motor for a spare and part out the rest of the 250x . wanted to keep the head pipe but looks like it has been welded and modded to fit the 250x frame . if thats the case then i would not really need to keep it if it will not work on my 350x . looking to part out this 250x to fund whatever parts i will need to buy for the tr200 fat cat i got from the same guy .posted pics of what it looks like let me know if you guys think its something i can use or if it should go to funds for the fat cat .

    The headpipe looks a lot like a 400ex one, as well as the muffler. I wonder if the system would bolt right onto a 350x? Its hard to say, I guess you would have to be the one to figure that one out.

    looks like 350x head pipes, or atleast the first 4 inches, then welded to a 400ex head pipe, then he end cut off to work with the 250x muffler. i wouldnt keep it if i were you...too cobbled together
