An L99 with headers and no tune has got to be very annoying with AFM. With a good tune you will definitely feel the increase in power especially the way the tranny will shift.

Actually from what I have seen and read from experiences the Res X Pipe is better at quieting things down than the stock Res.
The stock res is completely hollow inside, its just a can with a pipe in and a pipe out. The Res X has baffling etc to help cut down volume.
I agree maybe he should let himself get used to it for a while, then make his decision.
Also when he takes it for tuning he can hear the car from outside, and get a better sense of what others hear. HAHA...I will add that this didn't help for me, as all I realized is how deafening my car is with the NPP flaps open.
