Would removing the catalytic converter from a Maximum XL 2007 cause any other problems to the car?

    Welcome to Motor Vehicle Maintenance & Repair! Without any other intervention, it will not pass emissions, and a dashlight will be on permanently. Not quite sure what you mean by "other problems"? Nov 18 '20 at 22:18
  • Thanks. Other problems like causing the sensors to malfunction or stop working. Nov 18 '20 at 22:31
  • There are O2 sensors which are located in cat will not longer be sniffing anything. This is what will be causing the dashlight I was talking about above. Other than that, it won't kill your car or anything. Nov 18 '20 at 22:46
  • Depending on where you are removing the cat could be illegal. Won't cause a problem for the car but could for you.

    Do you mean problems other than increasing pollutants coming out of the exhaust? In the USA and many other places removing the catalytic converter is illegal.

If you remove the catalytic converter, basically your car will just be louder and you will go through gas quicker. It won't cause any actual car issues though, so you're in the clear.

  • If the OP lives in a state or country that requires smog checks to renew vehicle registration or license, or to sell the vehicle, it won't be too long before there is indeed an "actual car issue." Apr 22 at 22:37
