Re: removing my catalytic converter
I am not sure which yr car you have, but removing the cats will increase sound... and h.p., maybe. If it is has a carb on it, it will work. If your fuel injected, you have a pesky computer and oxygen sensors. They have what is called "upstream" and "downstream" oxygen sensors. Basically means one before the cat (upstream), and one after the cat (downstream). If the "downstream" oxygen sensor monitors no changes from the "upstream" oxygen sensor, the computer MAY signal a 'check engine' light and RETARD engine performance. So, you'll get a bit more sound, however, the performance may suffer, that is if you do have that arrangement of oxygen sensors....???
