Palenon Performance proudly introduces our high-flow race downpipes for BMW’s N63R and N63B 4.4L Twin-Turbo V8 engines—one of the most impactful upgrades available to deliver unmatched performance gains and sound enhancement. Expertly engineered for precise fitment, these downpipes are compatible with the BMW G30 M550i, G11/G12 750i, G14/G15/G16 M850i, G05 X5, G06 X6, and G07 X7. By removing the restrictive factory catalytic converters, these downpipes significantly reduce exhaust back pressure. The result? Noticeably quicker turbo response, increased horsepower and torque, and a deeper, more assertive exhaust tone. When paired with tuning, expect gains of up to 50+ horsepower and 60+ lb-ft of torque at the wheels when properly tuned.
