I don't think the R/T even gains much through intake and exhaust. I only picked up about 14HP. The autos may do better, but my 6 speed exhaust wasn't very restrictive, I just wanted more sound so I went with a Magnaflow. My tune was pretty aggressive stock as well so I didn't even do a tuner. The autos benefit more from a tune. The stock intake is a CAI, more so than even the Mopar I fitted to mine. I just did the Mopar because it looks nice, but I don't think it helped much in performance, maybe 5HP.
I'm still on the fence with the whole deal. Keep in mind my car came with a lifetime power train warranty, so I dunno what I'll end up doing. Intake and exhaust are fine, but tunes and obviously superchargers would definitely raise some eye brows if I ever had to have warranty work.
I've only seen one guy do heads/cam on his SRT and he got a pretty decent gain. I wanna say he got into the 11s with those mods, but don't quote me on that.

11's? no way unless he had some other mods to go with it... maybe the full make up CAI, Exhaust, Tune, Cams, Heads, and slicks...
Whats the word on the more powerful 6.4? should get interesting now that Chevy has committed on the Z28
