The XP series exhausts from MBRP is for the no-compromise enthusiast who insists on a rugged system that can take whatever the road throws at it and last.

That's why MBRP sells it with a lifetime warranty.

The first thing you'll notice will be the rich, mellow sound delivered by the chambered muffler. The second thing you'll notice is the improved performance as lowered backpressure and improved scavenging let your engine deliver more power and torque. The third thing you'll notice is more money in your pocket after you fill up. With all the tubing mandrel-bent without reducing its cross-section, and every bend made to the minimum bend angle, MBRP exhaust systems can substantially reduce backpressure through the system. You don't need to expend horsepower forcing exhaust gases through a pinhole, and improved scavenging of those same gases means more mixture drawn into the cylinders for more power. It's a win-win deal. MBRP engineers all of its systems to fit perfectly the first time. You'll be able to install your MBRP exhaust system with nothing more than simple hand tools. MBRP's XP Series systems are constructed entirely of T409 stainless steel, and feature polished mufflers and polished tips. Application-specific mufflers, developed on the street and on MBRP's dyno, assure a mellow but authoritative tone.

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.
