I am looking at the banks monster and the MBRP duals. I want them to be loud, well, as loud as they can be with the cat on, which might not be too loud at all.
well all of them will be close to the same sound,your cat will hold back the bulk of the sound and in all truth i guess i dont quite understand why you would want to keep it on there! i wont void your warranty or anything like that!
MBRP is an awesome setup and makes for a very clean install.

What are the regulations regaurding cats? or where does a person find the info. I thought it was a huge fine if you didnt have one, but maybe I am wrong.

That one small cat up in the front.. I had that in for a few months after installing my MBRP single 4" setup. It was loud and I was pumped after buying the new LMM and it being so quite I had people say, "Jim, you bought a gas truck?" Sure enough I ripped it off fast hah. After getting that last front pipe I started it and HOLY AWSOME TURBO BATMAN did that truck sound 100% different and way way deeper and turbo was so perfect sounding.
Liek everyone said so far.. If you want loud rip the cat off. Its only loud when your mashing the carpet down. Otherwise come up with a real good reason you want that cat in. It won't take long until you go in and cut it out.

honestly go with a turbo back exhaust... you will be glad you did. The only thing that the cat will quiet down is the turbo whine... I ran my truck without the muffler and with the cat for a month and then ripped the cat off now it sounds bada$$.
