Milltek Z-Pipe Upgrade for Secondary Catalyst Bypass, BMW G80 M3 and G82 M4
An upgrade for owners already running a Milltek 102mm mid-pipe or twin straight pipe secondary cat bypass. 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.
