i have a 2008 mazda 6 i sport VE, i wanna get an exhaust, mainly a cat back exhaust, but idk what is good for the mazda to get a nice clean loud sound. i have looked up exhaust systems but it says it doesnt fit my car and i dont have tools or anything to bend piping to make it fit...anyone have recomendations on what i should look at and what exhaust is good?
