Does anybody know of an inexpensive way to make the computer on my car believe that the cat is there when it truly isn’t? Or should I just leave the cat on? Oh yeah in case anybody is wondering 40 series delta flow flowmaster muffler makes a noticeable difference in horsepower gain. I just put 1 on my 06 ss/sc cobalt, its awesome.

DOES ANYBODY HAVE ANY SUGGESTIONS?

 

get a spacer for the rear O2 sensor to pull it out of the exhaust so it will read "lean".

 

I believe the people who go catless just get the code deleted. You can just do that I believe...
