Any 2 chamber turbo style muffler will get the sound you want. A 3 chamber will really decrease the sound to a low rumble at WOT and no big difference at idle. My biggest suggestion to you is to get rid of the monsterous cat that came on those things. It restricts more sound than anything. Throw a nice high flow cat, 2 chamber Flow and 3" pipe all the way back and love the sound. For a true performance upgrade look at going headers back with an X pipe and a pair of 2 chamber mufflers, along with the high flow cat. You would need to bypass the O2 sensor or purchase two cats($$$) to prevent the SES light from coming on though.
