Loudest Muffler for 5.0 TBI?

What is the loudest sounding muffler for a bone stock 5.0 tbi? I know the motor is a dog but id like it to sounds like it runs 9's.

I know a guy that ran a cherry bomb in place of a regular muffler, and welded a y pipe on it so he could have duel tail pipes. It sounded pretty sweet. I like loud.

I am assuming it is a chambered muffler.

yeah its a chambered muffler. I also don't have a cat either and i noticed the car got much louder after i removed it. obviously headers will help bring up the volume too

Another vote for the Aerochamber. Nice and mellow during cruising. Doesnt have that Flowmaster drone. It's very nice when you hit the throttle, very nasty indeed.
