I just recieved the Cobalt-Addiction shorty header and i sort of expected what i was going to get, there were rough welds on the insides, bumps and burrs at almost every seam . So i have spent a good part of the day getting buying special dremel parts and dremmelling down some problem areas that may inhibit flow. Just in case i was checking for thin spots to possibly see if i effed up, and so i just happened to look at the header from the outside with a light shining on the inside.

To my astonishment i saw a little sliver of light shining through a weld in the header in the collector between all of the pipes. Suprisingly this actually wasn't a spot i had dremmelled either. Now, i'm just sitting here wondering what i should do. Return it or somehow fix it. I don't even think its a hole, its basically a thin spot where you can see a tiny pinpoint of light, too small for a camera to catch. I don't know if CA would allow me to return the header in its dremmelled condition anyways, so i was wondering what would be a good way to patch the spot short of welding more material onto it?

I don't mind living with slightly inadequate headers, they only cost $200 bucks and are powder coated stainless. I'm just hoping this is a fixable problem, not a detrimental one (i dunno if it could create more failure of the weld).

 

holy crap that is too bad,it seems some of their header is good and others are not

 

**** man thats the first one I heard of with that problem... E-mail him.. I'm sure he'd be more than willing to take care of it for you

unfortunatly they are closed til monday...

 

On another note, what kind of exhaust gas temperatures are people experiencing with aftermarket gauges? I was wondering if J/B weld could plug the hole or if its just a futile attempt.

 

I don't have an exact # number for EGT but being a forced inducted car I would say it would be pretty high..
on a side note I did completly melt the internals of my magnaflow muffler with my side pipe setup so that should give you an idea

 

I would just exchange the header and hopefully the next one won't have the same problems.

 

Hey guys this is a little off subject, but would this set up work:

CA Header [Which has the 2.25" stock size collector]
XTC Stainless Steel DownPipe [2.5"-3"]

Aren't those supposed to match up in size in order to fit? The collector being 2.25" and the DownPipe 2.25" as well? [I'm still one in training about all of this...]

I want Corsa sport exhaust as well...Not sure the specs on it.

 

Well you can open up the internal part of the collector flange a bit if ou want.. I have it with a 3" dp and seems ok
