i have had 3 dc headers on my 96 they all cracked:madfawk: so i just bought a 1 piece 4-2-1 comptech s/s tig welded header damn what a show piece of a header very nicely made strong as hell and great midrange pull. it was a show piece header when i put it on but now its gold and blue but still a awesome header:thumbup:

 

Where did they crack? And how can tell if your headers are cracked other then visually looking at? (any sounds?) How is DC's warranty? Now I'm scared about mine cracking.

 

it cracked on the driver side between where the 2 tubes are welded together for cyl 1 and 2.. DC warranty will cover it if you are persistant with them being it usually cracks after 3 yrs but you have to send it to them to be inspected and they make you pay the shipping both ways.
the way I could tell it was cracked was the smell of exhaust under the hood. then you look at the header where the 2 peices bolt together and there it is a nice crack right next to the weld.
the header tube is what actually cracks not the weld.

 

That sucks about how they made you pay for the shipping both ways. It's not like the headers are fooking cheap. (money wise) If I could do it over again I would have gotten an apex-i header to go with my RS exhaust.
