Simple is good.
All I suggest is that you use the existing pipe, then mount, tweak and add to the end of it all you want.
It is not the most efficient expansion chamber but it does function as at least your 2-stroke version of a 4-strokes exhaust valve via tuned back pressure.
Just attach your final pipe to the little end of the stock pipe is all.
But hey, your bike bud, just trying to help ;-}
