I am running a Flow master super 40 on my 2003 Yukon XL. Just picked up a 2001 Yukon XL 2500. I am looking for opinions on what muffler to go with. Mine sounds great but I am looking for something a little deeper and louder on this one. I can only afford a muffler and not a system since I am spending money doing a 6 inch lift on it.
