Hey guys. Help me out. Right now I have all 3 stock cats on... no resonator... and two flowmaster 40's in the rear. If i GUT my two cats coming off the headers, will that give me a nice hollow kinda sound to it? Only thing is... the 3rd one will stay on and NOT be gutted. Also, does Dennis' chip turn off my Rear O2 Sensors so i can gut my cats without and codes being thrown??? Let me know what u all think.
