Major Exhaust leak, and other exhaust problems

I jsut recently got a long tube header, and put it on. The problem is, the EGR tube on the header is not bevelled like the one on the stock exhaust manifold. Therefore, a huge exhaust leak remains, and its very noticeable. They do not make a thread size for this in any type of adapter either... so I have some questions....

1. Why would a company design a header that doesnt even fit correctly?
2. How would I fix this?
3. (Unrelated) Why is it, that when I ran headers on stock exhaust vs headers with straight pipes, the car is faster with the stock exhaust?

Thanks a lot yall

what kind of header is it? does it feel faster with stock exhaust or have you taken it to a track and compared numbers, i believe with FC race headers you lose some low end torque but gain more top end?

Well the easy quick fix woudl be to find a plug for the egr tube on the header and plug it. Then plug the end that goes into the intake manifold. Now some pepole will tell you thats a bad thing cause the egr helps keep cylinder temps down yada yada but it wont efect anyhting but maybe send a cel off. At least it would make it driveable till antoher solution was found.

yea what header did you buy?? Im guessing one off ebay if stuff isn't working correctly. Blury gave a good fix, you don't need the egr except for inspections, just bypass it...plug it up. the car is faster with stock exhaust vs straight pipes??? That sounds rather odd...if anything you should pick up some for less restrictions. Do you have strip numbers?

what are the gains of takin the egr away and is it still emmisions legal. Does it cut the gas mileage down at all? I had the same problem with a header i got on ebay you should throw it out and go get a new name brand that backs their product.

yea ebay headers aren't worth a damn...as is much of the other "performance" stuff on ebay. You get what you pay for. As for the EGR, its basically a huge mess that you don't need really. I think if you bypass the EGR you will not pass emission testing or inspection at all. Gas mileage...dunno. Gains...im not sure. Most people that do away with the EGR are people that have a track car...where all they need is the basic motor to get them around the track faster. EGR just takes some of the exhaust gas and runs it into the intake to be burned again...so it probably does mess with emisions
