Product Details

Universal XP Series™ 409 SS Round Gray Exhaust Muffler (M91031) by MBRP®. Muffler Inlet Diameter: 4". Muffler Outlet Diameter: 4". Muffler Body Length: 24". Muffler Overall Length: 30". Muffler Sound: Mild / Stock. Muffler Configuration: Center - Center. Short on space under your car for a muffler? A round muffler might just be the ticket to tuck in around a drive shaft or up near the cats. Choose whether you want a raspy, straight-through sort of exhaust note or a milder tone. These durable T409 stainless steel mufflers will never corrode, and will last the life of your vehicle.

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.

Awesome Exhaust for my GMC Canyon!

This MBRP exhaust looks and sounds great on my 3.7L GMC Canyon! I have put a Flowmaster Super 44, Magnaflow, and Cherrybomb Extreme on my truck and NONE of them compare to this exhaust! I highly recommend this exhaust to anyone who wants more power and awesome sound!
