Default Performance Mods on '09 Superglide

I have an '09 Superglide with a heavy breather a/c, rinehart crossbacks, 103" kit, plus Andrews TW55 cams at a 9.5/1 compression ratio (milled stock heads). I'm making decent power (92HP and 104TQ) and enjoy a nice, flat torque curve, but I'm ready to take it up a notch, performance-wise. I'd like to get over 100HP and 110-115TQ, If possible. It would be nice to keep the same cams, but improve top-end performance with headwork alone. If I need to go to a different cam, I don't want to sacrifice on midrange power between 3000-4500rpm.

What would be the least expensive, most effective way to go about this?

A 2 - 1 pipe will put your hp# over the mark you're searching for without changing the power curve you currently enjoy.

Certainly do your own research but you will find virtually all the 2 - 1 pipes will offer nearly identical performance gains, it really boils down to finding one that pleases your eye and your wallet.

Good luck and let us know how it turns out.
