which flow better, or which is just a better product? For a 500hp 489ci
either one should be able to support 500hp pretty easily. My choice would be the EMI's but its a margin call, i think both are pretty good products.
Use the Gils. I have sold about 100 sets of the EMI's over the years and had more problems than I care to remember.

i say stainless marine
Gil or SM. I can get you either. Both are good products and flow & fit well. :) Jamie / Lakeside
What about the Dana's with the biggest vortex cone configuration ?
If your exhaust holes in the transom are for a standard Bravo template, then go with CMI Unitops. About the same price as a good manifold/riser exhaust.
I think they stopped building the Unitops. I may be wrong, but I thought that was the case.

thanks guys, the reason I posted was because I already have GILs on my motor but have a chance to put on the EMIs or leave the GILs. Sounds like i should leave the GILs
Yes, you should.

Unitops are still available and are very affordable.
Let me know if we can help.

your gils are better but, stainless marine last for ever, it seems like theres a lot of CMI headers used that need work done. I talked to a few guys about the big e top and they all pissing water need to be welded then I figure I will be chasing it even a good buddy of mine had to have his etops weld last season he told me after 4 years chit I got twice that on my sm gen 2s but with a 1000hp those will cost power and the reg etop will to it sucks that you can send 6 to 7 grand and after a few seasons they need work and you hope you don't blower a $40,000 motor:ack2:. so I looking for new sm gen 3s 5'' they aren't pretty but for half the cost of ss headers and its proven the gen 3 5'' work just as good on big blowers I am there I give up on used.
art, you are right ugly, SS marine great product ! Think, Walter runs'em on his race boat- 39-Sutphen and they last for a long = long time, like the old style hardin marine p-1000 series any 1 have that experience ?
