How much more Horsepower will the bike gain??

Dual exhaust!
Answer QuestionIt really depends on what machine it is that you have with regard to how much power gain you can expect. While top-end power may not increase the most, every Yoshimura exhaust is going to make more power in the mid-range. In other words, the RPMs that you use the most stand to gain the greatest benefit. However, these gains can only be realized with properly tuned fuel delivery. We recommend the installation of a Bazzaz Z-Fi, Dynojet Power Commander or jet kit. If you're after top-end gains, the only guaranteed way to realize power up there is to open up the engine and do expensive work there.
