This is possibly the best muffler you can install on a V-6 engine. I put mine on a 3.9 L Mopar along with stainless steel headers with 2 1/2 " duel tailpipes and I think it sounds and preforms very well. Also, they will last longer under even servere conditions. I would recommend this combo to anyone that needs performance and reliability without sacrificing fuel economy. Plus polished stainless steel just looks awesome.
