I will talk to the vendor tomorrow and see if he can exchange me this one. I think that Evopolice gave me some comfort, maybe I will give then a chance.

DC Sports doesn't have a very good reputation for crack-free headers to begin with. In the Honda world, it is quite common for those headers to crack after a year or so. Don't even get me started on the ceramic ones. I'm surprised however, that yours cracked with so few miles on it.

One more observation to pitch in is that this header are very thin in my opinion.
I showed the header to some of my friends with Turbokits and they quickly mentioned that this header were to thin and light. I think the main issue here was the welding joint, I believe they were faulty to start with.

i would love to see that

Ive read and said this hundreds of times.....regardless of how these are constructed, most of these mass produced headers will crack over time, some longer durations than others.
Take for example the better brands. I'll start with Mr Buschur followed by AMS, Full Race, RnR, TT and so on...
Buschur uses stock CAST IRON ported manifolds (I think) and proprietary manufactured headers that are cast of iron, which is proven to be significantly more durable over the long haul than tubular headers.
Now, tube headers made from this flimsy crap they call durable tube headers is undersized and basically is going out the day its put in.
The domestic guys, especially AMS and Full Race use some seriously beefy piping to weld up their stuff....reading off of Full Race's website, I see they use forged steel tubes, robotically welded....which in essence means that they are using one tough set of materials.
But they are just about as durable as an average cast manifold...which, for all intents and purposes is some rough and tumble $hit.
Dave Buschur conducted a stock turbo study of ported manifolds and tube headers, he found the only one to increase any horsepower was the full race unit.
The rest are just piles of wasted money that look really nice.
I would stay with the stock manifold or a ported version for anything except larger turbos, starting with a 20g...maybe not even then.
The benefits are outweighed by expense and lack of durability.
