no exhaust

[yehaw-yellow]

well i took the exhaust off of my GT and drove it around for awhile and it seemed to lose power? is there a reason for this?

yeah, you have zero back pressure which I'm guessing results in a huge loss of torque.

lol, what he said ^

sure sounds good with the lopeyness, but will run like crap.

Sometimes back pressure is a beautiful thing,

yeah and your 02 sensors dont have anything to read so your air fuel ratio has to be off

depending on how much of the "exhaust" that you took off you can also be causing damage to the exhaust valves driving it like that

yeah ive heard that before too, something about cold air rushing in and touching the hot exhaust valves..??

I've only heard that happens when you have open headers...once you put a mid-pipe it is long enough to make sure the cold air doesnt get to far up the pipe.
