Need aftermarket Exhaust for a 496HO.

Good luck with that. I lucked out and found a set of red powdercoated 496HO Lightnings with about 10hours use for $2000, complete. Even came with O2 sensor still attached and a F.A.S.T. 2-channel O2 handheld scanner.

Saw these on a previous post. Hope this helps.
I have a set of Full Polished Dana Exhaust Marine Flow Torque Manifold with Polished Stainless Steel Risers (short) and custom polished Stainless Steel exhaust tubes.
They were on my '06 Domn8er Deck.
They are in perfect condition, with no defects. About 55 hours on them.

Yes, ANY BBC exhaust will FIT. Unless they are 496 Mag / HO - SPECIFIC, they would have to be drilled and tapped for the exh water temp sensors on each side (somewhere in the water stream) AND an oil filter relocation kit would have to be purchased / fabbed. Mag/HO specific kits will have all of this already. These are just standard BBC.

I have a set of 496 HO / mag manifolds off a 2006 Shockwave on my 505 (bored and stroked 454) and does not have any provisions for water temp sensors. Are all years the same?

Yes, all the same. There is a temps sensor on each side. They are SMALL, go in the top surface of the main manifold area, just fore or aft of the flange where the elbow bolts on. There are probably pipe plugs in yours.
