S&S 55mm Performance Manifold vs Stock Plastic Unit

The only part that was changed was the manifold. Swapping from the OEM plastic unit to the S&S 55mm Performance Manifold

Definitely worth replacing the OEM plastic unit for an increase in HP & TQ relative to the cost of the S&S cast manifold. The cheapest 3HP you’ll find.

Results:
Improvement of 3 ft-lbs from 2500-3300 RPMs
Improvement of 3HP on the top end
