Very slow acceleration... o2 sensor?

I installed a MPx downpipe without a cat this morning. I drove it around for about two hours and the power difference was incredible. My engine check light came on after about 2 hours of driving. I stopped at a stop light and upon it turning green, I had no power. My car could drive, but I couldn't accelerate at all. I was a turtle. When I put my car in neutral/push in the clutch, I can rev like crazy. But if I'm in gear and I try to go, my RPMs go up so slow and I accelerate like a handicap cart in Walmart. I THINK I blew my o2 sensors... But I don't want to be buying and replacing things if I don't know for sure. Any suggestions?

it is exactly your o2 sensors you need to have a programmer on your o2 sensors for the car to work correctly. your computer is shutting you down. they are smart my friend!! LOL


go to your local muffler shop and or shop and ask for help!
