Hey
I just bought a Dc Sport header for my 2001 Z24 cavalier, i noticed that were the O2 sensor goes, its reading one cylinder ports instead of all four ports. Which i noticed every header read all four, just the Dc sport header read just one.
So i was wondering if it will give me problems?
Thanks for the help
 
I have a DC header on my 99 with a supercharger.  You will not have any problems with the o2 sensor location.

never had a issue with mine 
although i prefer having the o2 read all cylinders on any motor 
 
 
 
2 Years on mine, no problems to date.
 
 
hows the fitment on that do you have to cut your factory exhaust for the cat?
THERE CAN BE ONLY ONE, i have already died once and im still here so lets just leave it on the track
 
um it comes with a test pipe cat delete pipe that take no cutting to install. if your going to install a cat then yes you will need to do some moding

DC Race Headers are a no-nonsense, CAD designed off-road only exhaust manifold which emphasizes maximum power. These headers are designed to achieve the highest possible flow by any means necessary. As a result, the catalytic converter is replaced by a straight pipe. (Optional flange is included to use the original Catalytic converter with this header) 
thats straight from the ttr site
i wanted to know hot it fits with a factory set up i already have a factory style magnaflo hight flo cat
 
 
the optional flange means to work with the header you gotta cut and weld
