When space under the car is at a premium, one of these round, slim mufflers might be the perfect choice. 6” in outside diameter, these can be sandwiched in places a conventional flat or oval muffler can’t, like in the rear under the fenders. They’re also good right after the cat under the floor. Although these two mufflers look the same, they’re very different internally. The mild-tone muffler uses a more conventional chambered design to suppress more exhaust noise, giving you a sedate exhaust note that won’t annoy the neighbors or the cops.139.76Brand: MBRP Part Number: M91031 UPC: 882963100764
Fifteen years ago, MBRP® started in the exhaust business by introducing the B&B Eliminator, a silencer that quickly became the best-selling snow machine muffler of all time. Exhaust system technology being as universal as it is, they soon branched off into cars, Jeeps, and diesel trucks, with amazing success. One of their secrets has been the practice of making as many universal-fit kits as possible. A couple of extra parts in the box means that a single kit might fit a number of different wheelbase pickup trucks, for instance. Reducing complexity in ordering is better for them, better for their distributors, and a great benefit for their customers, who are more likely to be able to find a kit that fits their vehicle on hand. In addition, they go to great lengths to make sure their systems fit properly every time. Careful attention to design and fabrication delivers a system that doesn’t need customization with a hammer to fit properly before the car or truck comes off the lift.
