Cat or no cat?

[militiadsm]

I just didnt know what the pros and cons were to running without a catalytic converter. I had always assumed that it would add mor flow, but have heard of people having problems with it. Any ideas would be much appreciated.

It opens up your exhaust flow alot, but if you have an OBDII system, your CEL will be on for a faulty cat. Your rear o2 picks up the same as the front o2 and the computer flags the code. There are ways around it though. Also, if you have emissions tests in your state, you will need to put the cat back on for testing.

Just pick up a high flow cat. I have a Magnaflow piece and I haven't had any problems with it yet.
