I recently got a cheap chrome tip from pepboys for $3.50 that just screws on. I got it because we had to sawzall my tailpipe short so it wouldn't get crushed in Moab. Thus, my exhaust was exiting before the bumper, which I didn't like. Anyway, because of where the exhaust now exits (under the bumper, not before it), the sound is mellower in the cab and a bit louder outside. It sounds good though.
