My son has an SRT-8 Magnum so I visit the Charger Forums often to see what mods they are doing. There are several ways to do the exhaust and they range from cheap to very expensive. I think if you remove the resonators and add the sraight pipes and tips, its less than $200. They sound pretty good stock and get meaner as you remove sound deadners and add straight pipe. Kook and TTI have headers but be prepared to spend some coin.
