Hi , just did one of my mistakes and bought a set of big tube headers (the one that blings when you open the hatch) after 5 hours of they started leaking . yes 5 hours from new !!!

i dont trust these type of headers any more and i am going for something more reliable, i saw the Stainless Marine Gen 3 and the Dana as well .

has anyone had one these headers ? which is the best ? which are the most reliable


by the way motor is a Dart 572ci makes around 650hp

no experience with Danas but the genIII Stainless are some great headers. I have had two sets and liked them a lot and never had any issues. Not many guys running the danas and i;m not sure why they seem like a really nice piece and i really like the way they look.

Probably because they had the same terrible experience that I had with Dana himself! Look up past stories!

Gen 3 if your baking big power
Gen 2 mild to stock power

anyone else has the Stainless Gen III ?

My CMI's popped 3 times so I went to the Stainless Marine headers 2-3 years ago. I'm not sure if I have gen II or III, but they're on a 525. I had my mechanic paint them blue to match. No problems, no power loss, same sound. Very happy.

how did you know that your CMI's were leaking ? because i went to change the plugs and noticed that the headers were leaking !
power wise its the same ?

So whats happening with the new 5 hr old headers, what brand ? are they taking them back

I bought used Gen IIIs .. much better than the Leaky 'sprinkler' Stellings I had .. not so much bling but peace of mind. Not sure you need the Gen III`s for 650hp.

No issues, I have two riser elbows for sale FYI.

yes i am dealing with them for a full refund if they dont agree i will publish them with pics and videos
