Milltek Z Pipe systems use a 3D Printed 316L Stainless “Z" Crossover Pipe that is designed to improve the tone of the S58 engine by merging the pulses of the exhaust gas flow from the cylinder banks to give an exotic sound with less rasp. Back pressure is also reduced using this design.
Under load the sound is cleaner and higher pitched while on deceleration the deep rumble/burble is more pronounced. The weight increase over a traditional X pipe is minimal thanks to the advanced 3D printed technology used in the production of this part.
