99+ V6 exhaust

I have dual 2 chamber flows on right now and I was wondering how the exhaust would change if I removed the CATS? I found a shop that will remove them for me for $100 and there are no emissions testing in Columbus, Georgia.

It will completly change the sound of the exhaust. Cat's, from my understanding, act as a sound dampener before the exhaust even gets to your mufflers. My guess, Your car will be about twice as loud as it is now.

yes, it will sound louder, but that isn't always good.

i've heard a cobra with and without cat and with cats sounded much better. with flows and no cat your car will sound rackety and well, ricey. for performance it isn't bad, but if you are doing it for sound then i recommend not doing it. v6's just don't sound as sexy as v8's and no v6 can ever sound like a v8, even a cammed, built s/c'd stang. and yes, i've heard them before.

ps - green ownz dis thread

Maybe go with 2 high flow cats in the rear? That should make it louder but not as loud as with the cats removed. That's what I would do

And why are you doing this. It sounds like *** with no cats and totally unneccessary you will gain nothing in HP and you will loose torque

In 2 years when federal law requires all 50 states to have federally overseen emission test you will be changing it back. just does not make sense, spend a little more and get catted Hpipe but even those should be your last mod after you do the head, cam and intake upgrades

Thats nice, but when you remove cats you loose torque.
You also gain slightly Top end power. But you wont really notice that.
I would recommend keeping your cats, or go with hi flow cats.
