I have a 04 Roush car with side exhaust. My current exhaust setup is Mac long tube headers, Lethal Performance off rd x-pipe, and Magnapacks and it's nice sounding in city driving as long as you keep the rpm's under 3k and it gets loud! After i get done driving with windows down i always cannot hear outta my left ear for little while but way the benefits to the negatives and for me i love the sound so it's definitely worth it!!
lol. I will upload a clip vid later for ya.
