I just got my dynomax installed today and love it. I picked up the muffler for 50 bucks at Dons hot rod shop at glenn and stone and had it installed at discount muffler on Ina for 40. sounds great
On a different note I took my truck back to discount today and as it turns out they did do a half ass job of balancing the tires when they first put them on. They said some tires were off by 5 ounces. They redid it and now it feels a whole lot better. I feel great about getting rid of the BFGs for the duratracs.
My truck is at the dealership right now seeing if it qualifies for the steering wheel rattle TSB. We'll see.
