dont get me started on the woes of N/A GT exhaust (droning, raspy, etc...)...just keep in mind that the 3.8 will NEVER rumble like a V8 and no muffler/resonator on the planet will make it so...that isnt to say it will sound bad, but a V6 has an angry bumblebee exhaust by its very nature and design...you draw a very fine line between flow and sound...in this case louder is not always better and you window glass and tooth fillings will thank you. This engine needs a chambered muffler somewhere in the system or it will be hard to live with...only you know what your ears can stand...good luck.
