Along with the price, I'd like to know how performance compares to the e-top headers?
Many thanks,
Yoryi

This fits in the old stock holes doesn't it. Designed for the rubber hose to go out to the tail. How much longer is it than the stock iron riser. Basically the questions is, how much of the rubber hose do you have to cut off to make them fit?

Also what is the price.

For the other guy, it is my understanding that this is not an upgrade for a standard E- top, this is designed for the guy that does not want to step up all the way to E top

Bill, am I right? I'll get a couple sets if they are priced right.

Thanks for trying to clarify, but my question was aimed more at finding out how much performance you forego by not spending enough to go all the way up to the e-top.

I am hearing from 1500-1900 but no one is for sure. If they are 1500 a set, I am signing up for 2 sets right now.

Regular E top is around 3K a set, but you also have to buy the tails.

What I am wondering also is if these would work on a 500efi app also??

I've been waiting since April 29 to get tailpipes from these clowns for my 525 EFI. I'd think twice about ordering in the middle of boating season

FYI guys, I pm'd Ateco and they're saying direct bolt-on replacement for Merc manifolds. Price is $2,850 for satin and $3,320 for polished, plus brackets. Not much savings over e-top frankly...
