Made for a broad mix of N55 powered models, including the F10 and F18 535i, the 535i GT F07, the F12 and F13 640i and the E70 X5 and E71 X6, the BMW 535i 640i N55 Z Pipe replaces the restrictive factory section to help the turbocharged straight six breathe more freely. High grade 304 stainless steel with mandrel bent tubing keeps the bore even through every bend, improving flow while standing up well to heat, rust and road salt. Reduced back pressure lets the turbo build boost earlier, giving these cars a smoother, stronger pull from low speeds and more confidence when overtaking, in both rear wheel drive and xDrive form. The BMW X5 X6 3.0T Z Pipe also gives the engine a richer straight six tone under acceleration, while staying quiet and refined at cruising speed. Precision flanges and clean TIG welds line up with the original mounting points for a direct bolt on fit with no cutting required.
