How come no plug changes?
Super easy and accessible on my manifolds, no header tubes in the way to get at spark plugs.
Installation takes 1/4 of the time , no header botls against tubes to fight with and more room in the bilge

Guys,

Is this a saltwater thing?

I do find the idea of a single dump valve (per side, if need be) on a solenoid that would allow for everything to drain at the flip of a momentary switch.

Thanks. Brad.

Just for what it's worth-
ALL headers are susceptible to cracking/rotting/leaking.
We replaced a set of 5in Stainless Manifolds and elbows on a really well maintained raceboat last year. They just rotted out. It happens to all of them eventually.
Flex flange helps a lot on CMI stuff. IMO that was some of the problem with the Merc sweepers. The GenX Sweepers with a flex flange don't have anywhere near the same amount of issues. We test the headers on just about every engine that comes through the shop. The only set I think I've never seen leak are CMI E-Tops. If maintained they really seem bulletproof.
We also have a 30 year old set of full stellings on the bench right now which miraculously don't leak...so it's all a crap shoot lol.

Saris,

Yes the E-tops seem to last (20 years for me) and flex I agree hurt the long tubes, why I asked if it is a stag setup. Seems Very few have a brace, think of all the SS hanging there AND I see guys stand on the tubes! But for a stag setup if I had one and it needs replaced, the old Kieth black cast manifolds that are pretty much long tube headers sure seem to be the way to go.

Dead people,

Look at a Fountain that has manifolds, the dam things touch each other in the center, I am a 58 year old fat guy with a 32, no way I can get my arms between the two motors. I would have to call the Good Doc feelgood every time.

...And I'm only slightly less fat and less old.

I just can’t figure out why people are still buying headers,if you have to test them every year. Buy Stainless Marine and you don’t have to worry about pressure testing exhaust every year,I have better thing’s to do with my time.

I don't disagree, but jeez are they pretty.

I think it's worth it to me to spend an hour or two on a rainy winter day to get to look at them all summer. My perspective will probably change as I get older

For me, I wasn’t willing to give up 25-30 hp per side.

This was done years ago on a HP 500 motor, I would assume as you go up in HP on a NA motor the more pronounced change there would be. The Eickerts I would think should be the closest to long tube headers.

How do you upload a .pdf?

I don't think you can. I'd do a screenshot of it and upload it in jpeg format.
