Changeing Exhaust
 

I want to change the exhaust on my 97 Cobra, I was thinking on going with the side exhaust, with a set of off road H pipes.
If I remove the cats will it mess the engine up with the difference of back pressure?
Does anyone know the local law in wisconsin about the side exhaust?

I have run off-roads for about 4 years with no difference in the way the engine ran, but when I would put the cats back on for emissions, it felt way slower and soooo quiet!! I say take them off, you'll never want to go back! :)
