Product Details

Universal XP Series™ T409 Stainless Steel Oval Chambered Core Muffler (UM1215S) by MBRP®, 3" Center Inlet / 3" Dual Outlet. These XP Series mufflers utilize a chambered-core construction for a mellower but unmistakably MBRP sound character. They’re fabricated from long-lasting T409 stainless steel, which will never rust out. Use these as a replacement for your OEM muffler, or to fabricate your own custom exhaust system.

Products FAQ's About


  • Corrosion-resistant T409 stainless steel
  • Chambered core
  • Fully welded construction
  • Mellow exhaust note
  • Lifetime warranty

By using a chambered-core style of construction, MBRP has assured these mufflers will have not only a mellow tone, but they’ve welded – not crimped – all of the seams for a long service life. Because they use no fiberglass packing, the exhaust note won’t change as the muffler ages. Choose the inlet/outlet style that meets your need, whether it’s a single inlet-outlet suitable for use in single-pipe systems or in pairs for true duals, or a single inlet/split outlet for building a system with dual outlets from a single inlet.

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.
