I don't have any flow numbers or dyno results, however my but dyno noticed a difference. I wound up buying Marthy's mid ship and keeping the R6 muffler. We will be eating ramen noodles at my house this month. Anyway, the bike coughed at first. I assume it was adjusting to all the extra air flow. After 10 seconds she smoothed right out. Took it out for a 30 mile blast on the parkway. Spooled up a little faster and the dead spot at 4500 rpm is gone. Sounds nice but not annoying. Decel pops are a given and i kinda like it, but i can see that becomming annoying after a while. I will block off that air box tube thing and see what that does.
Marthy thinks that with the sound suppressor baffle thing removed I would be wise to get a power commander, but with it installed i should be fine being that it restricts the air flow some. It's gotta flow better than the stock fart can that came on this thing. The stock outlets are pretty small. I noticed zero ill effects whilst hauling ass tonight. I don't care either way. I think it looks awesome and it seems to be working great.
I am going to do 4 sound clips. Stock headers with the r6 muffler with and without baffle installed and Marthy's mid ship headers with and without baffle installed. I will try to get it done tomorrow.

Any idea if this setup will interfere with a Yammy center stand? As long as it sounds good, I want this setup pretty badly. Sound clips? How much was it for both the midship and the coffman?[/IMG]

Yep! Been done with a TB shorty slip-on.
