Milltek Z-Pipe Secondary Catalyst Bypass | BMW G87 M2 Non-OPF - Fits Milltek Axle-Back
SKU: SSXBM1429
Description
Milltek Z-Pipe Secondary Catalyst Bypass for the BMW G87 M2, Fits Milltek Axle-Back
A secondary catalyst bypass mid-pipe for the S58, built around the Milltek Z-Pipe in place of an X-Pipe, twin straight pipes or resonated section. The Z-Pipe is a 3D printed 316L stainless crossover that merges the exhaust pulses from the S58's two cylinder banks. The result is a more exotic note with less rasp and reduced back pressure. Under load the sound is cleaner and higher pitched, closest in character to the Nissan GT-R (R35). On deceleration the deep rumble and burble are more pronounced. Advanced 3D printing keeps the weight increase over a traditional X-Pipe minimal.
Key Features
- Secondary Catalyst Bypass: single 102mm (4in) mid-pipe replacing the factory secondary catalyst section.
- Z-Pipe Crossover: 3D printed 316L stainless, merges the bank pulses for a cleaner, higher pitched note.
