FWIW - I worked with Curt Hogan to get the DP made for our cars. Here'* the link to give you an idea of the performance gains:

At the time, my mods were 3.5" FWI, VS Cam, PEMs, and a 3.3 pulley.

Good luck.

And i now have that same DP from the Dyno chart on my car. When installed with the 3" High Flow Magnaflow cat i could feel a slight seat of the pants difference.

I felt it when I put mine on, but it is noisey. Not sure if it is just mine.

I didn't know you had a 3" DP. Mine is really loud but still pretty low and not too raspy at lower RPM'*, especially when pulling out of gas stations or drive throughs. Higher RPM'* i mostly hear blower whine.

My tone is low also, what I mean by noisy is it pings like a leak, but I don't think it is leaking, just "noisy"

Our exhaust setups are almost identical i think with the tips being the difference so i assumed yours was low as well. I know what you mean by "noisy", I'm not sure if it'* my DP or the highflow cat but something is kind of "ticky" in mine too.
