I recently added Stainless Marine to my 7.4 MPI.
For those interested in the weight savings:
Stock: per side
Manifold – 41.2
Riser – 12.6
Total – 53.8
Stainless Marine:
Manifold – 19.2
Riser – 7.2
Total - 26.4
The total weight savings is 54.8 lbs for both sides.
Not huge but they definitely look better.
