Peace, mercy, and blessings of God be upon you. I have a stock Mopar 5.7 Hemi cat-back exhaust. The cat-back is clean, stock, and has the catalytic converters removed, as shown in the pictures. It is free of leaks and problems, God willing. Its sound is enjoyable and mellow at the same time. The price is by offer, and we won't disappoint the serious buyer. It fits Charger, Chrysler, and Challenger, as far as I know.
