blitz claims up to a 20 hp gain from their exhaust. s&s claims 17 hp. has anyone done a dyno to get real world numbers?

Do a search. I have a dyno on the headers which is where S&S got their numbers. 20hp is too high for the Blitz-perhaps 5-8 at best. Headers offer 28lbs of torque as well. Keep in mind that many mods are not accumulative. So with headers and exhaust you may get 20-22hp total.

forgot i posted this. about how much difference would you say it made in acceleration? if you had to guess the 0-60.

Though I notice more grunt off the line I feel much more punch over stock once I'm rolling at around 50-60 and hit it... but as Lee mentioned, it can be a cumulative effect w/other mods, so I'm not sure what just my headers add... but I would guess my 0-60 time has dropped by at least 1/2 a second, since I pull away from my brother's stock SC off the line by a couple car lengths by the time we hit 60 or so, and that distance increases significantly as we reach higher speeds.
