i see what ur talking about, its only for the 7th gen and not 7.5 gen which doesnt make since but at that price i wouldnt trust em, sound like ebay headers.

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.

yeah look around for deals on dc headers. I got my Ceramic one for a good price brand new and in box, but I am soo scared about the flex pipe.

[suleman_manji]

don't do it. did it as a test since they were going for so cheap, still ended up getting a dc sports header.

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?

[suleman_manji]

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.

hey i also have sort of a hissing sound since i got my headers installed... all welds looked good before i wrapped them
i also have the ceramic dc sports 4-2-1 headers....
i feel a definate increase in power....but the sound is just different to me.... i dont think hissing is what i should be hearing
cant tell unless i have the car running while on the lift

[thisaznboi88]

Thanks tim! great advice as always. ^^

But yeah its getting annoying now because there is a buzzing sound. I am afraid that I would be losing power.

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

[timot_one]

It sounds like a cracked flex pipe.

[k24low20z]

x2 on the cracked flex pipe..i had to replace mine 3 times. warranty ftw!

[thisaznboi88]

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

[timot_one]

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.
