i have eliminate all 4 of my cats...

headers with all 4 o2 sensor plugged in and straight pipe and borla exhaust
no CEL, one thing I do not like is that it's too annoying loud...
sound like a muscle car

so I'm going to put the secondary cat back to see how it sounds like...

Jeffrey, how does your exhaust sound like with headers and bored out secondary cat??
