True dual exhausts are the idealized system for the performance driver. Nothing sounds like a V8 motor with dual exhausts, and that stereophonic burble in your ears when you stand behind one at idle. But from a performance standpoint, it can be improved on. An H-pipe, one that allows some exhaust gases to spill from one side to the other, can add some bottom end scavenging without reducing power at nearer the redline; it’s a win-win deal. The sound at low speeds will be slightly lower and rumblier, while missing some mid-range rasp and drone. This 3” H-pipe attaches to the stock catalytic converters
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.
