i got a problem here.... ordered some headers off ebay thinking they would be ok

http://cgi.ebay.com/ebaymotors...&rd=1


i have a few questions....when i got them the top flange that bolts to the head the drilled holes are way off..i tried to aline it with the gasket and it was wayyyyy off

they are suppose dc 4-1 rip offs but they have a 2" collector and i know dc has 2.5"

soo they arent the same...they are carb eo

when i bought my car it came with a HKS cat back exhaust..
bolted to my stock headers...soo does this mean the HKS piping 2"?

and if i got new headers with a 2.5" how would it bolt beside going to a muffer shop and getting them welded...


and i have heard of good brand also having problems with top flange not being drilled right....so is it worth it drilling them or dumping another 400 and going an-r's?

DC offers a 2inch collector on their US header, and a larger collector on another model to mate up to the JDM cat and exhaust.

soo that is why they are carb eo legal?

how does 2.5 bolt up to a HKS cat back...does that mean its 2 inch piping?

DC's larger collector header is not carb legal, only the smaller one is, both the 4-1 and the tri Y.
You'd have to have a little custom work done to make everything bolt up. Unless you have the tools and skills, you might have to visit your local muffler shop.

soo the hks cat back thats on the car now is only 2"

soo it would be the same as stock only have less bends?

Wow it's 2in?! Thats pretty small. It's still bigger than stock, and it's got a smoother flow without the harsh kinks of the OEM cat back.

Thats why you don't buy stuff like that off of ebay. I guess you had to learn the hard way. Oh, btw, its 'header' not "headers".
