what worries you about the cam? the power curve?
I don't know that cam profile but if I was going to build another one, I'd probably stay at 2" exhaust. that 2 1/4, man when it came on it really came on but the exhaust note was a little too tinny and crackly in the power. Could have been the muffler too, I didn't spend a lot of time trying to figure it out.
Everything online says to do a full exhaust. One thing I am not a fan of, is a noisy exhaust. V8's sound good with dual pipes and glasspacks. But 4 bangers, are just annoying as hell. I should be ok with the exhaust I have. Factory manifold, gutted cat, new pipe and a quiet muffler.
