there is a huge thread about what rim size is best. hit up a search. as for exhaust, unless you are getting mandrel bent piping get 2.25" or else it will kink up too much in the bends over the axle and won't flow as well. magnets,

not touching the rim issue ...

i second the advice on the exhaust question though. if you're running a 12A, i think 2.25 is the biggest you should go ...

i know, i know - you're wondering ... but diabolical1, MindTrain runs 2.5 on 12A and 13B - and they're opinion counts a helluva lot more than yours ...

True ... but i'm just speaking from my own experiences i got my best 12A results with 2.25 inches, the 13B handled the 2.5 better, but i still felt the 2.25 was that much stronger on the street.
