American Custom Pipes
First off - Visually stunning. Which, I hate to admit (as I'm not too much into "bling" for the most part), is why I ordered them in the first place. Slash-up with those black anodized inserts - those are the best looking pipes I've ever seen. It's everything I loved about Rineharts, but with the slash that puts them over the top.

Okay - Sound-wise... No baffles = freaking loud. A bit "sloppy" sounding (for lack of a better term) also. Didn't care for it. So, I put in the ("Mid-level") baffles -- Seemed a little tame, but didn't really road-test it (it was raining at the time).
Of course, anyone who knows me knows what I tried next... Right baffle only. Loud with a very generous rumble. Sounds freaking wonderful.
Still, for me, too loud for my neighborhood... I come up the driveway after midnight pretty often. Even on the road (after it stopped pouring), I felt a little "Uh-oh, I probably sound like "that guy" (the guy with the really loud pipes) or something... Hope I don't attract the attention of the local constabulary..." coming over me.
So when I got back in the garage, I let it cool down a bit and installed the left baffle once again. Still haven't given it some miles with both baffles, but it sounds pretty respectable from what I can tell. There's certainly the option of drilling a few more (larger) holes in the left baffle to give it a little more low end.
I'll probably add more once I get a chance to really hear 'em out on the road.
All in all -- Superflow's Max2's (actually again, just the left one) really spoiled me -- $150-ish for great sounding exhaust that isn't too loud? That's off the hook. With these AC's, being over twice as expensive basically for the cool-looking end caps, well, you could certainly spend a lot more. I don't feel any particular "buyer's remorse" or anything though...

Loud (for me), but not really obnoxious. The guys at the dealer liked the sound and loved the styling.
Went ahead and ordered the "quiet" ("stock-type") baffle... That's a long baffle (length of the muffler) in the right side, short (one of the "mid" type) baffle in the left.
Rather nice actually - Definitely more throaty than stock, definitely not too loud. Wound up drilling around 10 1/4" holes in the short baffle to cut a little back-pressure (the difference between "vroom - vroom" and the vroom with a sudden stop and "crack" at the end). Easily my favorite - A nice throaty, deep idle, a decent but not obnoxious growl at higher RPM's, a deer-alerting 'crack' when you give a quick quarter-twist, a subtle, healthy-sounding but 'radio-friendly' rumble at highway speeds.
Sounds like a Harley, but without being "that a**hole down the block with the really loud bike."
