I'm going to get the 2" quiet baffles when they become available(mid July) and put those in. That will help the low-end torque even more.

Funny, i don't see the dreaded low end torque loss because of the True Duals.
Wouldn't closer to 14 be leaner? Air/Foel ratio 14/1?
Keep in mind that the what you see on that graph represents the AFR at 100% throttle. Therefore, unless you run at 100% throttle all the time, it is not an indication of fuel mileage. Usually, tuners will give you a little richer (closer to 14) tune at 100% & back down closer to 13 at 3, 5, 10, 20, 40%, etc....

Yes, vernh... you are right. I had it bassakwards. That'll teach me to try to ASSemble thoughts after my bed time!
For God Sake, don't tell my wife I WAS WRONG!

Let me know what you think of the sound level. I am interested in those too. I found a thing at Wally World (Sonic stick?) something like that. Anyway, it measures sound levels and it is advertised for kids that want to SEE HOW LOUD THE SPEAKERS ARE[:@] It would be interesting to sample some exhaust systems so we could get closer to "how loud are they." I don't know how accurate this thing is but it should give some comparison info.

I have a Radio Shack SPL or DB meter, I use it to tune in Home Theaters. It is also handy to do exhaust comparisons, and I'll do it for sure. Bub claims that with the new '06 Rineharts, at 2500 rpm that it is only 98 db. My Thunderheader 2-1 at 2800 rpm measured 104 db.

Ok all I have another question....
I had my bike dynoed.... I still have the 8° injectors in.... I want to "complain" and get the 25° put it. How much can I ride this afterwards with the new injectors to get it dynoed again? I talked the the guy today and he said he would do it....
