Made for the X3 G01 M40i with the B58 3.0T straight six, the BMW X3 M40i Z Pipe replaces the restrictive factory section to give exhaust gases a smoother and freer path. High grade 304 stainless steel with mandrel bent tubing keeps the diameter even through each bend, improving flow while offering strong resistance to heat, rust and road salt. Reduced back pressure helps the turbo build boost earlier, giving the SUV a sharper throttle response and a strong, confident pull when overtaking or climbing hills. The BMW X3 G01 Z Pipe also brings out the rich straight six sound, adding a sportier edge and a few crackles on the overrun while staying calm on long family trips. Precision flanges and clean TIG welds line up with the original mounting points for a direct bolt on fit with no cutting required, making it a great base for a remap or further tuning.
