First, DO NOT mess with the CAT!It's a federal offence and can mean jail time if caught!Going Sidewayz wrote:...and if you can punch out your catalic converter. thats easy horsepower right there...
Second, a non-clogged cat does NOT hinder performance. NO HP gains by punching one out vs. a clean/new one. Depending where you are (smog tests) testers can tell based on your emissions if you've tampered with the CAT or not.
If you suspect your cat is clogged, take it out and look through it.It should look like a honeycomb, but you'll be able to see light through it easily.
