Slower after installing OBX Header

[chrismo240sx]

i finally got done putting an obx header in my 93 hatch....the egr plug gave me problems lining up but i cut the pipe and got it to thread in and now i have a hose connecting the missing pipe section.

...after the install, my car feels slower then when i didnt have the header, could it be running rich? or whats the problem? i also have aem intake, high flow cat, and 2.5 in brm exhaust

i also ran the car w/o the egr threaded in for about 3 days and it was faster that way then having it all plugged in and connected so idk....anyone else have this problem or have any ideas?

Clogged EGR, and running pig rich are my votes.
