Jeff - Good point about the sidepipes. After having my custom 393 stroker on the Dynojet (chassis dyno), I was disappointed with my numbers as well (391 rwhp and 386lbs of torque). At first, I was perplexed. With a 15% driveline loss, that's only 460 at the flywheel. My motor was built with a 520hp flywheel combination. So, I was about 50hp (rear wheel) short of what we expected. I have stock Superformance pipes and I've been told the same thing - they probably cost me about 30-35 hp. Hard to believe, but those damn pipes are way more restrictive than people think.
Anyway, to boost my ego, I may go back to the dyno one day and remove the pipes and run with open shorty headers to see the real difference.
In the meantime, do you know where I can find any photos or sound clips with the mufflers you mentioned welded into the sidepipes? Does it look decent?

Thanks.
