Yes, but also he was running a BOV and thus affects the air being metered possible. Then again, people have passed aircare with a BOV and the stock 2 downpipe cats.
Some of the guys in Cali have passed the sniffer test with just one cat in the downpipe.
Uppipe cat is for cold start only.

Forgive me for being rude, but just like Necromancer said, you're worried about your bumper? This is the air we all breathe, and for a few more horsepower, you're going to spew out not a little more, not a lot more, but more than 30 times more pollutants? That's downright obnoxious. Please, do us all a favour, keep ALL your cats on.
