what is available for it. What will it change?

I was wondering what is available for the 83-84 r exhaust systems. And also If I went to a 81-82 r motor would it change anything speedwise and powerwise.

the 81-82 has alittle less power, dg still makes new pipes, but better off looking for a old school sectional off ebay for it, alot better power made with those
