Some recommendations. I am putting a mild 383 (est 325 horse) in my 95 18 with Alpha. Marine exhaust sytems are new to me. Please provide what you folks recommend and cost is a factor.
If anyone has some for sale let me know also.
Thanks in advance

You can do GLM aluminum manifolds and risers for $750, or the manifolds and SS risers for maybe $1k. Typing on the phone so will keep this short, but lots of good info here if you search. Stock stuff or GLM will support your power level and work with a marine cam.

Yes I think any center riser with a vacuum break for resonance reversion will work on a 325 hp 383.

merc uses their standard risers on their 383 stroker 350 hp motor the 400 hp version of the 383 uses merc spec'd cmi headers

merc also mates the bravo to those motors, that is in the area where alpha can be suspect.
