can it be re-welded?
more than cracked is like the weld came off,
is a 4-2-1 DC header, and I really dont want to spend money on a new one, so is either fix it or back to stock

 

had this same problem so thats when i got my drag III manifold no but seriously i went to a shop and they charged 70 bucks to weld it completely shut. it was also 4-2-1 dc sport. good luck

 

wow, this is the first time, i'm hearing about this.... is this on a ceramic or ss? And if it is something of poor workmanship as it sounds like, then i would think a big company like dc withall their inhouse facilities would be willing to help remedy the problem. What exactly was teh cause of this? Just regular use?? hmm...

 

im pretty sure dc has a lifetime or atleast 10 year warranty so i would bring it back

 

here is pics of the crack,

I would get a used JDM type R header. If you weld it, it might crack again.

 

I got a crack along that point as well on my crappola dc 4-2-1

I tried several different "manifold leak filler" compounds, nothing seams to work permenently. eventually that stuff just flakes off.

 

so if this is a common problem like this, has anyone ever tried to get ahold of dc and see if they will repair it??

 

No way it's that long, it's 2 a year warranty. A lot of people buy the CC headers to save money but the SS is a much better buy if you plan on keeping the car for a while. CC headers crack much easier than SS and do not last as long. Welding once crack on a CC header will bump the overall cost to the price of a SS header.
