I personally don't know of anybody who has used those headers but I would recommend against anything other than comptech or DC-sports. DC has their own problems with the flex-pipes cracking. The only recommendation referring to header purchase is to buy something that's not made by OBX, Ebay, or NOPI.

I have DC headers and Overall, Great mod I can feel the low end tq come back. it wasn't as good as the pulley but its pretty good. Also it smells right now I think because all the pb blaster and stuff is getting burnt off.
Another thing does the car make a whistle at like 3k+ I looked at the header before I installed them and the welding looked shitty for DC headers. There was chips inside of both of the tube that goes 4-2. The 2-1 the flange was welding kinda sideways like 1-2* off. O well it was a fun experience. I will never do it ever again lol.
I just check the headers for leaks today but I can't find anything... I had it run warm up and i moved the TB so that it would rev and stay there looked at the back of the headers and there was no smokes or anything that was blowing out. So just wondering does anyone have negative comment for the DC Ceramic Headers?

that sound you are hearing is from the flex-pipe being cracked.

The best way to check for an exhaust leak is to use a mechanics stethoscope. Looking for smoke isn't the proper method.

I just order another exhuast manifold gasket. If that doesn't work I am going to order the Down piping gasket. It has to be leaking from one of the gasket. I googled it up last time and it sounds like a gasket problem

It sounds like a cracked flex pipe.

crack flex pipe? Even if they were new? If so do you guys have a flexpipe that you could recommend to me? I have them on for less then 100miles.
Like I listen to the youtube video with broken flex pipe and it sounds like a Harley. My car just goes Buzzzzz.. Psh

Take your car to an exhaust shop, ask them to find the leak, and let them know that these headers are known for having flex pipe issues. When they tell you that your flex pipe is cracked, have them cut the DC one out and replace it with whatever they recommend.
