Exactly, which is why I have have the stock crossover pipe on my Sporty with modified slip-on baffles. I have all the WOT I need, but with enough reversion that I haven't sacrificed any mid-range torque to get it.
I also have a new stock cross over pipe w/ hooker slip-on exhaust (old one had a stress crack down by r/s passenger foot peg)

On the subject of LOUD PIPES I must say, I don't like them. They're annoying to pretty much everyone within earshot and they're make our (motorcyclists') image with the public even worse than it already is.
BTW, my stock-mufflered 1000cc V-Twin powered bike makes about 90 HP and will do the quarter mile in about 11.5 seconds, which makes it more powerful and quicker than about 90% of the loud-piped Harleys on the road, all without pissing off all and sundry. And given a place to do it it would run all day at or near its HP peak.
