I haven't read that and I find it extremly hard to believe.
Maybe a stock header vs. an aftermarket header WITHOUT a PC III. But with a PC III and proper dyno tuning the bike should at the least make the same amount of power as stock; but more than likely it will be making MORE power and with less weight than the stock system.
