HEy man,
IDK if your still around. Lord knows I havent...Lol
I saw your thread and wanted to answer......
YES...
It will work. You can check my black S9 out..
I run the RS2 on the stock cyl./airbox.. (the s9 needs the stock airbox IMO, easier to tune and quieter.
I have the stock cab jetted to a 102(probably needs a tad bigger now with this sh** weather here). I run 55mph all day..(vids of the black and purple s9 here somewhere...annnnd the ag's 50+mph run)...
....... yeah I was bragging on myself....Lol Never have mastered it tho of course...
Hope this helps....
