well i had my obx headers on for about 6 months now and i just checked them today and found a hairline crack :angryfire . can this be rewelded and about how much would it be.
does a hairline crack like this effect performance?
sorry for the large picture but its the only way to see the crack

 

the engine vibrates and move quite violently udner stress. this crack could be a start of a larger problem. you sohuld repair it soon as it'll probably only get worse and eventually leak air by which time you'll start getting loud noises from your engine bay. it shoudln't be a difficult repair.

 

i dont see a crack >< maybe im just blind...

 

I see it. (took me awhile though)

I think all welds can be repaired.

I would get it fixed ASAP.

 

It can definitely be repaired it’s right on the weld so it so come out fine, and yes it will make you loose on performance and the more you push the car the bigger that’s going to open up, go to a muffler shop where a pro with remove them and weld it right, all around

 

i still dont see the crack

 

look right under the bolt on the left. there's a line going around the weld of the header tube. compare it with the one on the right.

 

all welds can be fixed

 

if you can't see that you must be blind. it may be possible to re-weld it, but most likely it will crack again.

 

well just got back from the track today and my time was a liltle slower then last summer. i ran a 14.50 @98.3 where as last summeer i ran a 14.34@98.8, conditions were about the same and both 60 foot were 2.28.

 

for thoses who couldnt see the crack, i updated the pic with an indication to where it is

 

You think thats bad, my OBXs have black sut all over the crack. And I def feel a power loss, can they re weld them while installed? or do they have to take them out to do so? So here's my to do list:

-Re-Weld the cracked OBX headers
-New Spark Plugs
-Upgrade to synthetic Oil, mobil 1
-change belts and hoses
-flush and refill all fluids
-steam clean the engine bay
-Have coilovers uninstalled and reinstalled hoping any noises will go away.

anything else you guys would suggest?

 

Yea Ron, they have to take them off so that they can weld right, all around the weld, besides, you don't want a half ass job or anyone sticking a torch by your engine. I have half of your list, don't know if you have them yet but since your changing your belts do your pulleys while you at it, it's what I'm gonna do

 

while they are welding the OBX's.... install CT's and then sell the OBX's

 

You get what you pay for. Unfortunately, with OBX, that’s not much.

 

anyone have any idea to how much this is gona cost to fix

 

Well with uninstall, weld, and install. Maybe $200-$300.

 

Checked my headers today and i have the same exact problem: a crack on the front middle pipe where it is welded to the flange. The same issue can be with the rear header, but cant see it.

 

Find a mom and pop shop that will do a good job and wont charge that much, if they charging you almost 300, might as well just get new ones and weld those for a few bucks and sell them like that to make a few bucks at least to cover the installation of your new ones.

 

and he has no clue what the REAR BANK even looks like...

that is not going to be a cheap $35.00 fix for you.

 

i would hear a weird noise under acceleration, and i found that my obx headers cracked in the same spot, i tried jb weld but it couldnt withstand the heat, it was a temporary fix for a few days.. i saw this other "liquid metal" product that says it withstands 2000 degree temps, you think this will fix the leak?

 

Why does every thread that starts with "well i had my obx headers on for about 6 months now" end in bad news?

 

That sucks. Get them fixed soon.

 

haha

 

as they say "got to pay to play"

 

Had the same problem...took them off myself(its not very hard) and payed the Midas guy $20 to reweld...shit ya gotta do to save ~$700

 

scary reliability issues with OBX . Are the alphawerks this bad too?

 

thank you obx headers is like saying no name headers and if they cracked once they'll crack again unless u re-weld the hole thing. good luck

 

hell no aw are extremely good headers. ive not to see a pair of aw headers wit problems

 

After like a year and a half, mine cracked. No leak yet, but it's all around the pipe. Oh, well. It was just a matter of time, anyway.

 

mine are gettin there too

 

had the alpha werks for about 8 months, so far so good knock on wood, when i give it gas at around 2500 rpm I hear this really weird hum sound, i think they call it resonance?
