Default need cats, what's loudest option?

i know not everyone is going to like this, but im putting in a cut out post cat (maryland emissions suck) and im wondering what the loudest possibility is for my truck to get when opening the cut out. basically, should i just leave it as is or should i dump it somewhere or maybe even install a second muffler/bullet (doubt that will help)

loudest for who? you? passenger? or cars to your left or right? Obviously the sooner the cutout the louder it will be. I promise you, dump it immediately and it will be f-ing loud. It will suck in the cab. IMO, if you want to do this, take it to the passenger side.

Where are you in MD?

a hollowed out cat will be the loudest, or one with a pipe threw it.

go with the magna flow 8inch cats..
they dont quite down the exhaust very much more than straight pipe.

Do a search for the magna flow cats on here and you should be able to find them..
I dont exactly remember the part number but it was 95#### or something like that..
I would have to go home, and look it up, but you could probably search for it faster here.

If you are only interested in having the catalytic converter for visual inspection purposes then buy a 50$ catalytic converter on ebay and hollow it out. I took a 3" hole saw and a hammer handle and put it after the Y-pipe.. The guys at the muffler shop got a laugh, and I got an inspection sticker out of it where I had previously failed the visual.

Good luck!

hit up member Whippled 496, he's in annapolis. He may know some one. I am down in Montgomery County. What ever a shop charges to put a muffler in is gonna be the same labor. Maybe a couple more bucks to put an extension on it. You can do the wiring yourself.

If you have the ability to tune, you can tune out the rear o2 sensors and gut the cats like everyone says. Or you can get o2 sims. The rear is just making sure the cats are doing there job. Your MD inspection can be visual but usually isn't. It is all OBDII plug in. You can't have any codes set and you need to have 80% of your readiness tests passed (pretty much). They reserve the right to dyno test or tail pipe test ya but usually will not. Maryland VEIP LINKY

I had my ecut out after the y-pipe, sure the cats drown the sound some, but LOL I assure you it's loud. Stock cats or not. Can it be louder, sure, gut your cats or get larger cats like mentioned above.
