I went with an Arrow in the matte black color. I ordered it direct from Arrow in Italy and the price was very reasonable. It has a removable baffle. I found it too loud with the baffle out, too quiet with it in. I ordered another baffle from Arrow to experiment with. That was pretty pricey, but I was afraid of messing things up if I started hacking into it. I drilled a new set of holes in it and created my Goldilocks dB killer. I also ditched the flapper valve and got a replacement mid pipe with the holes welded up.

I think the bike sounds pretty good. Itís not so loud that I piss my neighbors off when I leave for work at 5:45, but has a much deeper growl than stock. Gotta love that sound ducs make under load.

Ended up going with the GPR. Won't be here til after the 1st so I'll update how I like it once it arrives. If I end up not liking it it'll be for sale next month and I'll save up for an Arrow or Termi next year lol.

I'd rather save my money on a retune to make the bike less jerky and improve fueling. If that is even possible.
Your data on the MiG is inaccurate...You may be quoting stats from Akra without cat-delete, which is just silly if you're going to put a pipe on for performance. This is how it acts with cat-delete:

- WITH DB Killer, little more bass/boom down low and throatier at full twist. Never removed DB killer because, as noted, stocker was loud enough and I don't enjoy pissing everyone else off with an exhaust that pops fillings out of your teeth.
- Charts I saw said 3+ HP; 5 with the full system. Hard to say as I have a tuner on.
- Definitely breathes and rev's better than stock. Probably little better with DB killer removed.
- Weight savings is probably biggest plus. It's easily 1/3 weight of stocker; maybe 5 lbs savings. That's significant on a 399 lb dry bike. Combine that with Lithium battery and removing or replacing useless plastic, you're talking 5% weight reduction.

Also, a basic tune should include a filter upgrade and free flowing exhaust. The ECU doesn't even care if you only change one of these.

Fantastic! Some side by side pics would be nice when you get cracking in to it. I feel that side by side pics help others that are looking to make a decision, showing what the physical differences are in relation to the oem. Plus, making a new post with "GPR vs OEM hypermotard"(or something like that) will allow people to Google search and see your comparison/pics. I'm excited to see what you think.

Interesting on the performance gain #'s. Ducati estimates with the full Termi, air box mod and remap about a 5% hp gain. Or 6 hp. 5 hp for the full Akra sounds about right is you do the airbox and remap.

The data was listed on the links provided in the thread. I don't own the data.
