What improvments will I see on a 22 classic 454/385 MPI if I upgrade from stock exhaust to stainless steel and what type should I go with?

I went with stainless Marine, with the stainless risers on my smallblock and it fit and runs/sounds great. Tell them you are with the Donzi Registry and they might give you a discount, He told me he gave me 10% off.

I actually haven't been able to run the boat enough to say exactly how much power, performance increases there was, because of other engine problems, but they seem to give it more power, and also droped a good 70 lbs of the engine.

I put Stainless Marine manifolds and risers on my small block in a 21GT. I had to have them make custome risers to clear steering etc.. I was very happy with the quality and fit. I have ran them 4 seasons in fresh water with no problems.
I made to many changes to really get an accuarate comparison, also I went from 3" to 4".
