    Power loss in my Phantom HS Kit?

    Ok so I have a Felt with a HS engine and Phantom Bikes Exhaust. My dad has a completely stock felt with an HS engine and regular exhaust. It seems that when i ride his, it has alot more power than mine. Could the Phantom Bikes exhaust be the culprit of this?
