Just the 800 pipe. Rich can make it standard or high elevation only. If you want max power runs JAWS Big Bore twins. If staying single, run Dyno port y pipe, stock pipe, and muffler work great. There is not much difference from stock pipe to dynoport, but with y pipe there is. I run Jaws twins on mine. Love it.
Thanx for the info.I have a dyno port single on it right now but was curious if it was 800 pipe or 860.Also have aftermarket y pipe but bought from Absolute 3 yrs ago and cant remember what brand it is but suspect it is not Dyno Port. SPI rings a bell but not sure could be way out to lunch
