Two of them to be exact. Whilst I don't have pictures of them just yet, I will soon. But here is the important picture/information.

Your HCs look really high for having cats. Mine got 20ppm at idle, less for cruise. And later I found 2 bad plug wires and the valve seals were leaking.

I didn't set the idle terribly lean. Did you try to pass with the 400 or the ol 305? This is with my semi large cammed 350. Still idled great!

I dare you to bring it to the Oregon DMV by my house, just to see how it does.

On the 400, it did better without cats than the 305 without cats, lol! I had mine set for 14.7:1, it wasn't idling its best with the problems around 52-53 kPa @ 750RPM. Now it's around 47-48ish, which I guess is ok considering the 110deg lobe separation. It actually passed the cruise test just fine without cats.

Limits are a tad different here, HC here is 70 cruise, 100 idle. CO is the same, they also do NOX for cruise.

It changes everywhere.... hehe noway dewey, I didn't have to adjust the pumpshot at all. I'm free for two years! YEAH! And I can put the cat back on the jimmy, and add the cutout to it. I idle at like 60kpa on a regular basis

2 cats, single pipe, certainly is quiet. I am seriously looking into something like dynamat to reflect the resonance of the duals. Still don't understand why mine is so damn loud.

Btw single 3" with dual cats = gutless car.... I can't even burn em off shifting 1-2! And it takes forever to wind out first gear!

Since when is a Camaro (or ANY 2-door car for that matter) considered a "SEDAN"????
I thought a sedan had 4 doors, and a coupe had 2...

Crazy DMV folks! Laughing
