Why would you drop the cash for a BB, and not get a high
perf exhaust?
Just wondering because I feel I got the most increase in power
by adding the Bubs along with bigger jets, and a UNI filter.
Flow in - flow out.
I personally don't think these bikes need the amount of air
that a freak or nark system flows requiring jets to 150 or more?

But what do I know?
