496 exhaust

I am rebuilding a 496 ,looking at a few options for the exhaust.
I am using a stroked crank,high lift cam and forged pitons & rods from Raylar amd Whipple blower.
I am thinking Dana ,Stainless marine or EMI all with dry pipes.
what do you think?

Probably the most $$, but you can consider CMI too. That said, I replaced CMI's on a 525efi w/ Stainless Marine and was please with the results, and the cost.

I wanted to use a manifold for reliabilty over a header which seems to be less reliable and more expensive

496 dry exhaust ?

IMO Don't waste your $$ on EMI, SM for this application. They are both short individual runner manifolds that dump into a large common riser. Exactly the same as your 496 exhaust. The only exhaust that have proven gains over stock are CMI, Lightning, Dana Marine.

Stainless Marine gen 3 seem to be doing well against headers.............and come with a leak free warranty for 5 years

They don't market a set directly for the 8.1 app. While the exhaust ports are the same BBC design, they don't have provisions for the EMCT sensors. You will need them added or deleted from the setup.

Thanks Ryan,
i can add the sensors to the thunder & lightings not sure weather to go with these or the lightnings as I want to get the max amount of height
the danas are another option but even with the 3 inch riser they are still 3/4 inch lower than the lightings
