Ok so this is my first post. I'm not much of a car expert, so I need some help. I have a 2001 V6. I'm getting something done to my exhaust, but I'm not sure what. I need a new muffler, and was quoted $150 for a flow master or magnaflow. He also gave me the option of going dual (with 2 new mufflers) for $450-$500. My question is, is dual worth the extra money? Also, feel free to give opinions on magnaflow and flowmaster, as I really haven't made my mind up on that yet, either. Thanks!
