Quality of construction is very good. Installation smooth. Slight drone at certain RPM range but overall a decent sound and not too loud for my taste.

Very good service and fast delivery

I already had intakes but with this exhaust I believe my Stinger can now breath full system. The system gives a nice low rumble that's not obnoxious.
My box showed up pretty banged up which did dent one pipe but a few taps with a blow hammer straightened it out.

Exhaust sounds fantastic! received in 3 days after shipping! unbelievably quick and precise, all works well and was very simple to put together myself.

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.
