High-flow cats = SES light?
Test pipes/high-flow cats users please advise on this.
Long story short. I installed high-flow cats and did the "CEL fix" by installing the spark plug de-foulers over the secondary sensors (1 de-fouler for each sensor) and did the hard reset by disconnecting the negative battery terminal.
The light went off but after driving 50 miles or so, the SES light came back on.. Any ideas on how to have this solved?
Note: i'm hearing a low hissing sound, does the SES light goes on if there's an air leak, or in other words, what causes an SES light to show.
Thanks.

Thanks Gary. I didn't know there were multiple codes for the exhaust system itself, i'm gonna have it scanned and see which code shows up.

i had some generic hfc's and i had the check engine light after the cel fix. I also had a hissing sound too. turns out i cracked my cat when i went over a huge bump. i replaced the hfc's with kinex hfc's and no hissing and no cel. Check for leaks. I used oem gaskets as well. the chinese ones leak.
