Question to hollow, or not to hollow

Ok, so heres the deal. i am thinking about hollowing out my 1st cat, the one next to the manifold.


some background:

a while ago i hollowed out the rear cat...i got all the catalyst out, but a small metal strap was left inside....after trying for almost an hour to get it out, i gave up..

thing piece rattles, and rattles, alot. and to top it off, abou two months ago, it actually lodged itself in such a way, it no longer rattled, but it also restricted airflow by about 60%.....so it no longer rattled, but it was clogging my exhaust.

so yesterday i get under the car, take the cat out to fix an exhaust leak. i see th metal piece, clogging the hole, and found a nearby set of needle nose vise lock things..and i managed to pull it out.

so i put the cat back on..no leaks: me happy. but also, i got this wnoderfull suprise. BETTER throttle response. better exhuast note (you can hear it now)


now the question is, i am tempted to hollow out the first one too....to get a louder and better sounding exhuast note, and better throttle response....

should i do it ?

Don't gut. Get a high flow cat. Yes, it will cost money, but if you drive your car on a regular basis then why pollute? A gutted cat section is still restrictive.

if you search the forum, you'll find posts where people gutted their cats and lost power......so I'd just recommend leaving them alone. Or if you're that concerned about them, replace the two stock cats with a single high flow unit.
