Ok I got the engine lights of p0420 and p0430 however it goes.
I'm in CA and they are very strict on cats here .I don't have 600-800
To pour into a magna flow cat.If I buy these SLP cats with it get rid of the engine light .Btw my cats that I have that are bad are bold on .
I have a 02 camaro ss .
Here's the link to these cats . http://www.andysautosport.com/chevro...a00205138.html

 

search the classifieds for someone getting rid of theres and pick some up for $20.

 

I got mine used here, that's my advise. A lot of people rip their cats off for header installs. Some will actually offer a good deal to a needy brother rather than the Scrap Yard. Post in the Parts Wanted section.
