I Think I F*** Something Up!

[BigCook]

I just bought a Dynomax super turbo muffler. When I put it on I decided to take off the catalytic converter and resonator. When I got it all put on I started it up and drove. Smoke came pouring out the exhaust. The smoke was white, but not coolant white. Also there was ALOT. Once I realized I forgot the reset the ecu I did. I took her out for another drive. this time no smoke until I hit 55 mph then smoke, but not a lot. Tomorrow I'm going to get the cat and res welded back on. Is there a chance that I did any damage to the engine? If so what did I do.I need help real bad.also, has this happened to any one else? All input is welcome.

Messing with the exhaust can do that, you probably loosened somehting you shouldnt or something just happened to break after you changed the exhaust. White smoke is usually coolant though

I know it's not coolant. It smells like exhaust fumes but real potant. NO sweet smell.
