With a stock motor and stock pipes, the can isn't going to make that much difference. Sure, it will breath a little more efficiently, but the difference is going to be small.
On a tuned system however, you could possibly see 1hp difference between silencers on a 300 I would imagine!
If Steve ever gets his to hang together long enough to reliably test it on the dyno, maybe we can find out!
