I purchased these and installed them without an issues and got a tune-in-a-can from BAMA Performance. After a short period of driving I got an error code of "Catalyst efficiency below threshold bank 1 and 2" . I called AM to see if they just sent me the wrong tune and their answer was pretty much short and sweet of, "There's no fix other than turn the O2 sensors off and you can't pass inspection" Hold the phone! Isn't that the point of the catted x-pipe? So I can pass inspection? I immediately called BBK and they told me that's a lie, the cats are there just for that reason. Absolutely I thought! BBK being in the business for 2+ years now I can't imagine they would lie to me. They told me that there's a way to tune the car to accept the higher flow cats. I called AM back and they give me the same story and even tell me, "Those cats don't actually work, well they work, but only 50% of the time." Really? Kinda like the TPMS sensors they installed on my wheels and only 50% of them worked too huh? Has anyone else run into a problem like this before with AM? I'm hoping they give me a proper fix action for both problems or I'm going to have to take my business elsewhere. Which is sad because I really like their website and the amount of products they have. However, I feel that poor service is an immediate change to where my business goes. I'd also like to ask anyone if they know of a fix to this problem. Surely with all the tuning equipment, software, and know how out there there's a way to program a computer correctly.
