Took the white car out today and was messing around on the street and all of a sudden it starts making this weird noise. I thought maybe the header came loose from the block. it made the car sound like a vw bug lol. it was puttering.

i had all 3 cutouts open and took off pretty hard from a stop when it happened. what would make this happen? The hole is where the egr pipe goes into the header. here is 2 pics to compare. driver side and pass.

 

WTF! ? What kinda headers are those? Are you running really lean?
I would think you'd have other damage too if that was the case.

 

I've seen that before.. I forget what brand header it was though.

 

shitty weld. Hot cold hot cold/expand contract bla bla bla.

That sux Man. Pull it off n have it welded up.

Depending on how long you have had them you may be able to get some kind of warranty replacement. But I would not count on it.

This is really funny because the same exact thing happen to me last night. I believe you had an EGR modification there right? Mine are hookers, what were yours? Same exact hole! Holy crap.

 

they are hooker headers that i bought from Jet Hot and had them coated. i bought them almost 2 yrs ago.

what else could have gone wrong?

 

Same exact thing happened to me last night. It is where the Egr modification goes. I am running the Hooker headers, where yours Hooker headers too?

 

yes

i went back in the Gold car and looked for the piece where it happened at, but couldnt find it.

are you going to get yours welded?

 

Ok, I know this is off topic but I just gotta ask...... 3 cutouts? I don't get it. If you've got one at each header collector open (assuming), then why would you need a 3rd one open?

 

i had the one on the I-pipe first before i had the other 2 on the y-pipe

 

This has happened quite a few times. It happened to me about 4 months ago. I just pulled the header, and had it welded up, and re-installed. Looking back on it, if you had a experienced welder, you could probably do it while the header was still on the car. No big deal, just a royal PITA. Good luck with it!

 

i've heard of this happening a few times now...that sucks... i used to have Jethot/hooker setup...
i got rid of it and went with QTP stainless race headers

 

silverghost had the same problem with his hooker headers as well

 

Yup, got mine welded yesterday. They are as good ad new.

 

cool.
im going to get mine fixed this week

 

I had a set of hooker supercomps that were jet hot coated and the same thing happend to them. They were not ls1 headers, but had identical problems. I bought them from summit and they replaced them for me for the cost of shipping them back to them. Sucks that such a nice header is built so poorly.

 

I don't think it's a build quality issue, I think it's just a matter of the heat expansion of the primaries causing them to expand and contract over time. That takes a toll and gives a lot of strees on those small welds. I am very happy with the quality of the hooker lt's on my car. The exact same thing I have personally seen happen to the "Almighty" LG Stainless Steel long tube headers for the corvette. It happens, and becaust of this, when i do get a new set of headers someday, I'll be getting the "race-ready" headers. They look better anyways!
