Is Any 1 Running A Thermal Three Inch? If So How Loud Is It. Im Tryin To Go Three Inch But Maintain As Much Stock Look And Sound As Possible. I Found This Thermal Research Muffler Part # 08-trd-81630s. They Sai It Was Quiet But The Only Thermals Ive Heard Are Loud As Hell. Let Me Kno What You Guys Think.
