    I want to replace my stock cat with magnaflow but I spoke to a performance shop and he said you have to get a California emission cat otherwise you will trigger your engine light. Now is this true? If so, does anyone know any websites that sell magnaflow cat with California emissions for cheap price. I found couple but there like 400 dollars which is crazy money....let me know =)

    Get a 3" Catted Downpipe from ZZP...awesome. Some high flow cats set the check engine light...some don't...it depends on the car...not all of them trip the cat codes and some do, who knows. Or, just get rid of the damn thing and get a o2 sim
