MBRP Armor Pro Series 3in T304 Stainless Steel Resonator Bypass X-Pipe for 2021-2026 BMW M3 / M4 (3.0L)

Fits 2021-2026 BMW M3 and M4 models (3.0L).

Unlock the acoustic and performance potential of your G80 or G82 with the MBRP Armor Pro Series resonator bypass X-pipe. This system is designed for enthusiasts who demand the highest material durability and a more aggressive exhaust note without the harshness of a full straight-pipe setup. By replacing the restrictive factory resonator with a precision laser-cut X-pipe, this upgrade balances exhaust pulses and increases flow by up to 17%.

Constructed from 3-inch T304 stainless steel tubing, this bypass pipe is built to withstand extreme heat and corrosive environments. Every bend is mandrel-formed to maintain a consistent internal diameter, ensuring maximum exhaust velocity and reducing backpressure. The result is a moderate sound level increase that highlights the S58 engine's signature tone while improving throttle response and longevity.
