High flow cat on a 94 3.4

[CAMAROWITHBASS]

I took my car into the exahust shop and the guy put it on the lift. He said the cat was bad, he would hit the cat and it sounded like there was a rock stuck in there.

I sometimes smell rotten eggs, sometype of egg smell coming from the car

The cat that is on there now is after market its like less than 2 yrs old.

Ive seen a lot of people around here that have a high flow cat from summit? I thinks its called a catco? Its 50 bux.

any one have any part #s? If i add the high flow cat will i need a o2 simulator?

go to summit.com and get a catco universal cat. Pretty cheap, about $50 I think. As for the 02, no, we have our o2 sensors in the headers

What size does the cat have to be?

3'' in and 2.25'' out? or is it 2.5'' out?

What lenght, width does it have to be?

I went with 2.5 inch in and out cat.
As for length, it doesn't matter, whatever will fit under there.
As for O2 sims, not needed

That noise is the honey comb that is falling apart inside. You could just continue to drive around and it will continue to break up and eventually flow out the muffler but the emmissions might not be up to par

With a high flow cat would i still pass emissions testing? i live in tx.
