Removing rear cats?

I was wondering if I removed the rear cats will it make my exhaust quite a bit louder or barely noticeable?
I want to free up my exhaust alittle more but mostly make it alittle louder.. thanks for any input! I dont want to do this if it wont change the sound any
Thanks!

 

Yes, it will make it louder. How loud will be determined by what muffler you have.

 

I have the larger dynomax super turbo muffler and is perty quiet

 

Could I just remove one cat? And see how it sounds? Lol

 

On my Audi, I removed all of the cats and ended up not getting aftermarket exhaust because it sounded so good.

 

Aside from being illegal in most if not all states, I don't think you'll notice any gains in horsepower. If sound is all you're after well yes it will sound louder, obnoxious most likely as well. IMO its hard to get a V6 to sound good. It takes a very well designed exhaust system to make sound nice and most will be pricey. Most of the six bangers I've listened to with aftermarket mufflers slapped on at a local muffler shop sound horrible under acceleration.
