does anyone know the size of the egr tube nut and the threading on the obx header? http://www.mazdas247.com/forum/showthread.php?t=123709368
I see that this is for the OBX style header, but for those who have an AWR 4-2-1 you want to look at how close your lower radiator hose is to the #1 cylinder pipe. Apparently AWR made different versions of the header, the one I bought had that pipe routed so that the hose was touching. I ended up going to a local auto parts store and they let me pull around in the back to find a replacement hose that would avoid the problem. If anyone is interested I can provide the part number for the hose (it surprised me how few hoses there were with the correct diameter).

found out the fitting coming off the obx manifold is 1/2" for future reference. i just went ahead and replaced the egr tube with water heater piping and gave me a few extra inches when i decide to do thermal spacer and finish porting intake manifold.

+1...this thread has all the info you need. http://www.mazdas247.com/forum/showthread.php?t=123634664&highlight=mil+eliminator Your mechanic is right, the OBX removes the precat, so you have to move the o2 sensor out of the exhaust stream to make it think it is getting catted (cleaned) exhaust gas instead of the actual raw exhaust it is getting.
FYI, if your state does a visual inspect for emissions, you won't pass...

I had this problem too.... odd thing is, it was the reason I bought the header. To get rid of the cat. Did you buy this not knowing its purpose? Follow the links provided above.

He has his OBX header on and all fits on top, but, he's now got an inch and a half gap between the bottom of the header and midpipe.
I suggested he attach at midpipe first, then see if he can get the top to lineup again
Anybody got any ideas? He's doing it now, and his wife is pissed at em cause she's waiting

Will a 19inch long 1/2 inch breaker bar with a socket get those midpipe spring bolts loose?
I don't know but its worth a shot. I ened up with a 5 foot pipe and a wrench to get mine. The thing came off with very little effort! Yes I had a lift and no I couldn't use the air tools(they where in use)
PB blaster the crap out of those bolts first, or you might torque em off. First night i tried to hit the stupid spring bolts, it was a no go. Shot PB blaster and let em sit over night and shot em all throughout the next day, then, i had a 2 foot breaker bar on my socket and it still took quite a bit of muscle, but they eventually came free

For your consideration: I really think a lot of it depends on how rusty the bolts and studs are are. The studs are welded to the midpipe, so if you bend or break one, you're going to have to drill and replace and that's going to set you back quite a bit of time and energy. My car spent time in Michigan before I bought it and with PB blaster my impact still took some time to get the nuts off. I've never seen an impact have as much trouble as it did for me on those nuts. I am sure I would have messed something up if I had used a breaker bar.
