I have a 2001 Durango. I had a 50 series Flowmaster... for about a month or so.. It was EHH not so loud.. I decided that i wanted it to be much louder. So me and my buddy Matt (aka Tani1500) went in and cut the muffler right the hell out. Welded in a piece of exhaust tubing and Wahlah no more muffler. Sounds INSANE runs great and if you want your truck loud go big or go home! [sm=yikesomg.gif]
