CMI's
 
why are almost all of the CMI headers you see out there either leaking or have been fixed because of leaking...who wants to destroy a 20 thousand dollar motor because there headers leak. why would anyone buy them?

So true. I succumbed to the hype and sent mine off for testing. NO problems. $300 (less shipping) for polishing...

6 plus years and never a problem. Think people are more inclined to post problems........hence the saying, no news is good news.

I'd like to know how many they have sold over the years.

Not a single problem with my big e-tops. It does seem like most of the problems were with the Merc/CMI factory headers. But as stated above, I'm sure the volume on those was quite high, and "no news is good news."

I am very happy with mine, and would buy them again in a heartbeat.

Love my CMI headers!

Toasted two 525's becasue of leaks! Drain them every time out and pressure test every season now.

Had mine e-tops fixed multiple times before finally getting rid of them.. Never had the pleasure of toasting an engine but didn't want to chance it anymore...

Several other 525, 600sci and 700sci boats at our marina had problems...

The E-tops are definitely better than the ones that come with the 525/600/700...

Any header, if it's welded stainless steel, can/will crack over time... Over the past 15 years I've seen it a lot.

rule of thumb for me...they have a 5-7 yr service life, shorter on the swept back 525,600/700...

I just saw a couple of 525's this weekend that had some reversion but no leaks, it was crazy. my E tops are 10 years old, and never a drop of water anywhere. I'm replacing them because of age, but someone is going to get 2 sets at a great price. :)
