I sold a '71 with flowmasters so by comparison the double-d's approach civilized. Under full throttle they scream but in average driving it depends on the rpms. They can be a little noisy around town but at highway cruising much quieter than prior toy. Unfortunately as to performance per $ , I have no idea as they were part of the package.

I'm trying to get info from Callaway about what's inside them, but I assume they should flow well enough for a 350 motor. They are 2.75" pipes with a 3.5" single mixing chamber (which is about the same as dual 2.5"s as far as cross-sectional area). Assuming they don't have any real bends or restrictive baffling, or any pinches, I'd think they should be decently maximized? I'm leaning towards just getting an exhaust and either a nice scan tool or some nice scan software I can use on all the cars, and that's it. I think I'd like to see what other cars are like with some of the other mods before doing them to my car. I'd also like to hear the exhausts first, though.
