The responses given in this thread aren't entirely accurate.Hey there,
I have a AEM CAI and a magnaflow cat-back exhaust. I wanted to know if I were to buy just the CP-E computer unit that connects to the ECU, would it work.
Also, were can I find it on your website.
We're starting to get off topic, but in most states, no. The single cat obviously will not clean as well as the 4 restrictive cats, but it will do enough to keep the check engine light from coming on. If your state has a visual inspection or does a strict sniff test, then you could have a problem. The only state I know of that has major issues with exhaust systems is California, though.thanks for the info. I was also thinking of geeting headers and using only one cat instead of for. Will i have a problem passing emissions with only one cat one the 6s?
