I've got the Akrapovic full system. Much lighter than stock and delivers a lot more power from about 5k rpm upwards (with re-jetting, of course). As you can see from Ivan's dyno charts here, there's a little dip in the dyno curve between 3.5 - 4.5k rpm. Not really a problem on the road, just slightly softer in response vs a stock EXUP header set up:

Most decent aftermarket full systems for the Gen 1 are no longer available new. you'll have to scour ebay, I suspect. Avoid the Sandy Spares version as they're not the product of proper design and testing.
Which system were you thinking of getting?
