Well, my cat went to shitsville today. So I was wondering if I should:

1. Gut the stock cat

2. Buy a carsound cat

3. Buy a testpipe

And I had a question regarding a high flow cat. Anyone know the life expectancy of a high flow cat? Anyone been running a high flow cat for a good period of time? Cause if they don't last, might as well buy a test pipe now, and when it comes to take emissions, but a high flow.

Let me know what you guys think. Thanks.
