MBRP 3" Active Profile Axle-Back Dual Rear Exit w/ T304 SS Carbon Fiber Tips BMW M3 | M4 2021+

MBRP's 3-inch Axle Back with Dual Rear Exits for 2021+ BMW M3/M4 delivers the perfect mix of aggressive tone on the throttle but remains refined on long drives. Crafted from MBRP's industry-leading and most durable material offering, T304 stainless steel, this axle-back is perfect for extreme conditions, like salt and heavy precipitation. This axle-back works with MBRP's 3-inch resonator bypass and is designed to bypass the stock resonator and increase pipe diameter to three inches allowing for a 17% flow increase over factory piping generating more power.

25 years ago, exhaust manufacturers were inflating prices and performance gains. The industry was missing a product that consumers could trust, with integrity, quality, and value. Martin and Ginger Barkey saw this as an opportunity to develop products they were looking for themselves, so they built MBRP with those values in mind.
