Not all mufflers are created equal. Magnaflow Race Series mufflers are built for the extreme conditions that can only be found on the racetrack or off-road. This is the muffler that you'd find at the Baja 100, Dakar Rally, and the X-Games. Like I said before, not all mufflers are created equal.

Magnaflow uses T-409 stainless steel when constructing the Race Series mufflers. A straight-through design helps to eliminate back-pressure, which is ideal for boosting the performance of your vehicle. Magnaflow uses a stainless steel mesh coupled with a high-temperature acoustic suppression material to reduce unwanted sound waves which can lead to droning. All factors were considered when creating these mufflers, including tighter race-track regulations on decibel levels.

If you're in the market for the highest performance muffler available, don't look any further. Magnaflow Race Series mufflers are exactly what you need to give your ride a leg up on the competition. Order yours today!
