Keep in mind that there are many things that affect the sound of the muffler. Some of the key things are cylinder displacement (as opposed to total displacement of all cylinders), how well the engine breathes through it's intake and exhaust manifolds, presence of a cat, and what the duration of the exhaust lobes are on the cam. These are all things that affect the sound other than the muffler itself. Doesn't sound like you really care so much about the sound though, so long as it doesn't sound ricey. Now that being said, a cherry bomb is almost by definition ricey. With the way a stock 22r is set up with the manifold and a cat, I'd so go with a Flowmaster 60 series delta flow (three chamber), or a 40 series delta flow (two chamber) if you want it a little louder. Either one would allow for future upgrades and still sound good.
