I just got a 2001 manual v6. I love the car, but i feel like something is missing. I want both a better look and more hp. I want to upgrade the exhaust system but do not know what to chose, i want twin pipes and two mufflers, but do not want to get a whole new rear bumber like that on a GT. Can anyone give me a recomendation on what would be the best exhaust system to install?
