I pulled the cat out of my 305 TBI and i noticed a difference right away. Sounds better, drives better, and as long as the pollution ****'s don't take a look under your car it's well worth it.

how can you "tune" the car so that it doesn't smell as bad w/o a cat? (besides plugs, wires, rotor and O2 sensor)...

"bad" is relative. I think it smells fine. If it smells horrible (like sulfer) then the cat is clogged. I'm not sure what you mean by "bad"

This thread has gone on way too long considering we've already answered the main question quite a few times.

You can either

a) remove it and put some pipe there
b) remove it and replace it with a high flow cat

Since you said you don't have any money, just go ahead and throw the old one in the garbage and put a peice of pipe there.

I hate to be a pessimist about things, but I'm somewhat dubious the cat is your "no power after 3000 RPM" problem. It sounds feasible, but a stock LO3 isn't an Indy race car either. 3K RPM is about when it falls on its face.

if you tune it right
I had a previous questoin about that, what exactly needs to be tuned so it won't smell as bad? (besides the basic stuff: O2 sensor, pulgs, wires, rotor,)

you gotta make sure its not running rich. running rich is what causes that bad smell if your running without a cat.

I wish I would have seen this before it got out of control.

Removing your emissions equipment is a FEDERAL offense, regardless of your state's emissions regulations. If you are caught, you can be punished by a fine, jailtime, or both. Please stop giving us hot rodders a bad name.
