what will happen if I do that
your car will catch fire and explode ... then mazda will roll up in black trucks and take you to jail ...



or you wont notice huge amounts of HP gains ... and youll ruin very expensive cat converters ...
 
Don't be polluting more than you already are unless of course you don't give a rats ass about air quality.....but i do. You won't pass emissions if you hollow the cats.
 
ure car will get louder and pollute more.

other than that, get a pick and hammer and pound away ;)
 
Dude i no a guy that did that to his infinity, the car sounds like a P.O.S. We know everytime he's commin by the noise and smell!
