just got 2.25" piping from the oem cat back, and a powertech pt1012(
http://www.cbwheels.com/powertechexh...ges/pt1012.jpg ) muffler, and i have
a high flow catalytic converter that a friend's dad is going to install..

my question is, he was curious if my car has a sensor for the catalytic
converter that tells if the cat has been replaced, or is missing or not
functioning correctly because if it did have one it's possible the car wont
start after he puts it on.. i don't think it does, but thought it was best to
ask around

thanks,

Chris
