the quoted HP increase is with JUST the midpipe (not rwhp mind you), the software and catback HP gains are supposed to be cumulative.
4K for software and a complete header back exhaust system is not out of line, not a screaming deal by any means but right in line with other manufacturers it seems.
I couldnt be more satisfied with the Dinan set up, the car is responsive, no reverb on the highway, a nice howl when you're on it, and isnt tuned on the ragged edge. I am a little worried about Dinans decision to move the redline up to 8600 rpm as its pretty easy to bounce off of it if you're not careful, but the fuel cut off is pretty harsh so I think the chances of running it to 8700+ would be almost nil
