Gen 2 Vader exhaust

[RK97]

Circling back and reviving this thread to ask if there is a popular exhaust option with known jetting preferences.

I believe i understand what will fit without modification, but i am still not clear as to what is cheap, common, and known to actually improve performance.

I will plan to buy a clone carburetor with the exhaust, and would prefer to just jet it (close to) properly from the start.

Thanks.
