The most gain we see from exhaust systems is around 2 to 2.5 HP, you get this gain from mid to top end 3500 up wards. If you want better pull from the very bottom end fit a 14T front sprocket, or a 46/47 rear sprocket if you still run on the highway at times.

Thanks for the tip. Does that mean that it's possible to loose some power in the low RPM's when going from stock to 3.party exhaust systems ?
Most of the time I am on "B-roads" 75-90 km/h. That means 2900-4000 RPM in fifth gear.
I am looking for a little more power when driving by cars, accelerating etc. maybe Powercommander and DNA is the only solution ?
Regarding the "repack" of exhast. Some producers give information about repacking, some does not. Is this due to different "build" or is it simply the fact that some producers don't see this as good advertisment.
As far as I know original exhaust don't need re-packing.
