definitly no bigger than 2-1/4.

depends on what you're running for a muffler & cat etc and also if you gonna get 2-1/4 with mandrel bend or just regular bends, but you need backpressure or you won't make any torque down low.

if its gonna be mandrel bent with a free flowing exhaust probably 2" would be just right.

2-1/4 non-mandrel bent will neck down to 2" or less in the bends which should be fine
