This exhaust sounds great: not over the top, but significantly louder and more aggressive than the factory exhaust, and unlikely to annoy the people next door. The tone is very deep, with nice gurgles and burbles when decelerating in-gear, and no tinny or metallic harshness (as heard in some of the other Stinger exhausts available). When cruising at highway speeds there isn't much in the way of drone, but when accelerating the exhaust makes itself known more than I would like at around 1800-2000RPM. There are no weird vibrations, dash rattles or other cabin oddities at any speed. At higher revs the exhaust really screams and makes me think I'm driving something exotic. I bought the stainless steel version and it came well packed in foam padding, and fitment was very good (however the coupler sleeves didn't seal no matter how tight they were cranked, so had to be welded). The quality of the exhaust's welds are OK, but fine considering the price and that no-one will ever see them. My exhaust took around six weeks to be built, but hopefully MBRP will start ramping up production to meet demand and turnover will improve over time. I was kept informed of progress by David at K8, which was great. Overall, I feel this is how the Stinger should have sounded from the factory.
