Just Came back from the Dyno. :)

Hmm. Ok. Maybe it just looks different to me in the pic -- I just seemed to remember the color/coating of my y piece looking different...
Anyways, nice dyno #'s, hope mine turn out similarly.

Looking at the dyno graph in this thread you would want to shift where you would stay in the power band the longest period of time...in other words what part of the power band does the most power ((torque X rpm)/5250) occur over about a 2K rpm span? If you were to shift at 5200 rpm's like you suggested then the car would fall back to 3.2K rpm's and have no power. But if yo were to shift at say 6.3K rpm's then you would fall right back into the heart of the power band, 4.3K rpm's.
A general rule of thumb is to shift 500 rpm's past peak HP

Rpm = mph x gear ratio x 336/Tire diameter
Rough estimate would be from this equation, reason it's rough is b/c the car is still moving foward between shifts, obviosuly, so then the next gear rpm will be higher than this equation suggests.
On a sidenote, VeeQue, mine look like yours, (they were I30MikeD's) and they are now on a 5.5g. I get a slight rattle from 2.5-2.8k someitmes, thinking it could be from tht weird bend ... not sure.

Since I have stock cat-back, it's not noticeabele at all, only if your ears are specifically tuned for stock 5.5g Maximas, come to think of it, I forgot how it sounded when it was stock compared to now. Those things helped out tremendously, my first drive, I was amazed, has a hard time keeping traction when flooring it mid -gear in 1st, and that's that I'm at anywhere between 5500'-7400'.
