I bought a 97 Concorde LX with a 3.5l to enter in to an enduro race. I cut the muffler off the back, but its still pathetically quiet. If i cut the cats off, it should be nice and loud.
Im nervous to do this though, because if the O2 sensors/cats aren't in tact, will the air/fuel mixture be wrong and make the car run like crap?
Do I have any options to liven the noise up and keep it running right?
