precisely!!!lol its that simple kinda.....theres metal screens on either side of the cat internals and its gonna take some work but on all the cats ive ever punched out thats all you have to do....it makes a mess though....

just make sure you take it out of the car completely before doing this and do it in an area where there is ventalation cause it makes a huge mess

If you're going to do this, please wear soem kind of breathing protection like a mask... all that stuff in the cat can be very harmful.

Why

Do not go through the trouble of gutting your cat...If you do some research on the DYNO numbers for this (One of the magazines even did this recently, I think Import Tuner) you will find that power is almost always LOST by gutting the stock cat, let alone you will throw a CEL and not be able to smog the bitch again.

The stock catalytic converters are designed to optimize power while doing the job it needs to do. When you gut it, it just creates a fucked up link in the exhaust that disrupts flow, and it does not even do any of the things a cat is put in your car to do in the first place.

If you want more power, get a high flow cat, or if you do not care about being street legal, get a test pipe that will smoothly take the place of the cat and not disrupt flow.

I agree, also gutted cats sound too raspy for my tastes.

Good advice. Me and a buddy both had minor nosebleeds for a couple days after gutting the up pipe on his WRX.

You may look like a loser in one of these
