Ive used a few dynomax mufflers in the past on other people's vehicles but haven't used thier bullet mufflers. Wasnt a fan of how thin the metal was and how quickly they rusted out and i was back under said vehicles putting on a different brand muffler. How is yours holding up? Id imagine if your further south than others it should last a while. My 97 i picked up still has its original exhaust under it but i was a southern truck most of its life. Nice walk through btw nice to see some decent exhaust diy fab work from time to time.
