Yamaha DT175C

Hi everyone,

I have the above bike and my question is, does anyone know if the front part of the exhaust pipe (from the cylinder head) is it the same as the exhaust on a 175A or B. I know the complete front section isn't the same but I want to cut the down pipe from a 'A' or 'B' and weld it to my exhaust as it is in a bad way.

Thanks
