I got the full Leo Vince system (4-2-1), with the titanium silencer with carbon fiber end-cap for 2011.
Fit: As with the previous Leo Vince system I had on my GSXR, this exhaust is beautifully crafted. The welds look perfect. All of the needed hardware and instructions were included. One of my favorite features on this particular exhaust was that the primaries are separate from the flange pieces that bolt to the engine. This makes the header install a million times easier since you bolt the flange pieces to the engine and then just slip in the primaries and clamp with a spring. The exhaust came with a bung installed for either the factory O2 sensor with a supplied adapter or a wide-band sensor. It also came with a replacement bracket that is smaller than the factory one for the bottom mount. It also has a rubber pad that maintains space between the left most pipe and the fairing, preventing it from melting the plastic fairing. The silencer clamp is carbon-fiber, very cool.
Sound: I haven't taken out the quiet-insert yet that came installed in the muffler. Looks like just an allen bolt to remove it. But with the insert in, the exhaust is just barely louder than stock. Supposedly it meets the European standards for exhaust noise. So, that works out good for me. I wanted to ditch some pounds but not make my bike scream too much. I'll probably get out and play with the insert removed sometime, but I'm content for now.
Weight: The package was 19 pounds for the exhaust, but that includes the box and all of the internal packaging, plastic, etc. It is very light! The feel of the bike now is so much better. I can't believe the difference in feel from the weight. After replacing the exhaust, ditching the reflectors and mud-flap, removing the passenger handle, and removing the pair valve; this bike doesn't even feel that heavy anymore.
Power: I really can't say here. I still haven't broken my bike in (only had it a few weeks), so I don't even know what the stock power was like. I assume the gains will be comparable to most other systems. I got a mail-order tune done on my ECU through EBAY, and the engine seems to be running good because of it as far as I can tell.
