Last night i was putting on some hooker headers and i was just goin to leave them open for now. I got one on then the other one wouldn't go on unless i got it on to a lift so i put one of the stock ones back on and left the other hooker on. The hooker doesnt have a place to put the O2 censor but the stock one did so i just put it on that one and not the hooker. Then once i started it and gave it a little gas it started shooting flames out of the stock one and then would just die. So i took the censor out and it still did the same thing. So if anyone knows what is causing this please write me. Thanks!

 

Not a good idea, no back pressure and you could suck in cool air through the exhaust.

 

Welcome to the forums, and I second Twotone.

 

it shouldnt be bad sinse they are long tube headers, so its not hurting anything but also not helping. on the stock header im running right now i have part of the down pipe still on, it gopes until the resenator or whatever that thing is. and its only shooting flames out of the stock header and down pipe, even at idle and just stayes lit the whole time, so im wondering what is causing this to happen? is it the o2 sensor or is it somethin else?
Thanks
