| The manifold is nice because it not only evens out the exhaust flow on both sides of the motor, but it's already drilled and tapped for an EGT probe as well.
Neither will make a huge noticeable increase, but both will give you slightly lower EGT's, and will work great in combination with a full exhaust system. We carry both, and can get you either or both if you'd like. Let me know if I can get you prices on either!
