Hi, I was just wondering which Magnaflow muffler would be the best suited (at a reasonable cost) for a stock 2.7 '04 Intrepid. Part numbers would be great. Also, direct fit bolt on is a must since I want to do it myself and have basic tools. Btw I want to change the muffler that hangs right after the fuel tank not the one that's connected to the muffler tip. That might be a resonator not sure but that's what I want to change. Thanks for your time!
