Building an old Donzi on a budget, putting in a 502, have 4' thru hulls installed, and using stock 454 mercruiser manifolds right now, would love to run something else, they don't have to be perfect, let me know if you've got anything laying around your shop

depends on the budget and where you are located. I have a brand new set of Gil manifolds that where used on a display motor but never run with a set of used dry pipes with mufflers made into them.

I have some CMI split top, dry pipes off. Bravo for 1500

I should have clarified, I'm running the stock wet exhaust right now, and am not familiar with a dry system, Ideally I'd like to find a wet upgrade to what I have now,
