All manifold kits include gasket exhaust and springs.

Shorter exhaust: gives less acceleration, but an increased topspeed.

Longer exhaust: gives more acceleration, but reduced top speed.

Conical exhaust: top speed higher, higher acceleration and higher fuel consumption.

Cylindrical exhaust: top speed lower and lower fuel consumption.
