This is not a donzi ?---but may appy to some of the larger models (i.e. 28 sportsman)Sorry for my ignorance, maybe somebody can help. I run a 31 bertram with BBC---Marine Power-premium motors that are suppose to be 365-375 hp at shaft---using rochester carb and and square port heads and stock Barr exhaust with center riser.I recently replaced risers but are looking for a better solution--is stainless marine the way to go-I can not get too radical with this application and there is about a 10 foot run from riser to transom exhaust with a muffler in between-will I enjoy any performance gains?
