I don't think you'll get a huge power increase from a full system. You'll prob have to get the bike dynoed and rejetted to see a gain of only a couple of horses.

I fitted an aftermarket slip-on exhaust and got the fueling done which gave me a couple more bhp. I wanted the exhaust for the looks and sound mainly.

I'd look at get a bigger bike if I wanted more bhp, though a nice exhaust or full system sounds great on the SV.
