By the way, if you're looking to a stage 1 upgrade--and I know you are--you might want to look at a pair of slip-on mufflers, as opposed to replacing the exhaust system entirely. I replaced mine with V&H short shots (chrome), then wrapped them in black fiberglass, then oversprayed with black silicone paint. I replaced the standard baffles (internal mufflers) with quiet baffles, but it's still really, really loud, to the point that I wear earplugs for any rides longer than a few miles. It gives off the Harley growl that was lacking with the stock pipes, and there's a noticeable uptick in performance, but the noise might be more of an annoyance than it's worth, and certainly to your neighbors, if that's going to be a problem for you.
In hindsight, I think I'd rather have wrapped the stock pipes and slipped on something like these (shown on your bike). Deeper sound, some degree of performance improvement, but a less abrasive decibel level. You can buy the wrap and mufflers for ~$400, or slightly more for black billeted heat shields as shown below, and the install is fairly simple:
I went from this (stock air cleaner already replaced with Rough Crafts high-flow cleaner):
to this:
and finally to this, chrome heat shields removed, black fiberglass wrap, along with custom seat & mount (rubber stoppers replacing stainless steel springs), grips, single-side saddle bag, front fender removed, black gloss headlight rim, and a few other personal touches:
I'm not sure I love the wrap any better than the chrome, though. It does eliminate the pinging sound that the heat shield-pipe combo produces, which is nice, and it gives it a more customized look (everyone and their mother upgrades to this exhaust system, as it's the best return on the dollar for performance and aesthetic investments). But I've seen several 883s and Fortys that have slip-ons, or that have replaced the stock with long, curvy chrome pipes, and it just fits this bike perfectly.
If you haven't browsed HDForum yet, you'll find endless threads about exhaust mods and what not. Also check out youtube; there's a bunch of before and after videos that give a pretty good representation of what different exhausts sound like on your bike.
