The car will run rough because of your rear o2's. If you hp tuner or edit you can remove the rear o2's. Also it will run rough because your not ballancing out both sides of your motor, IE ypipe or Xpipe. Oh and silver is right get your self some ear plugs.

It will be LOUD and slow. A lot of people have driven open header for a fair amount of time, but you do run the risk of washing down the cylinder walls with gas and burning up your rings. I myself drove open header for a few weeks while waiting for the apt to get my duals installed. You would need about 18" of pipe after the O2's to keep them from getting contaminated by outside air. This is harder than it sounds. i had a shop make a copule extensions for me out of 3" pipe that was expanded on one side to slip over the headers. It wouldn't fit on the driver's side because of the floorboard getting in the way where the stock y-pipe is crushed for clearance.

If your just running them to get to an exhaust shop or something you'll be fine. If not, pick up some 3" pipe and make some 16-18" extensions. It's easiest to make a butt joint with a band clamp. On the drivers side cut the Butt of the extesion on a slight angle and you'll als0 have to flaten the pipe alittle with a hammer and a 2x4. You can flatten the floor alittle too. On teh passangers side all you have to do is bolt the pipe to the collector, no clearance issues.
