BMW N63R/N63B Catless Race Downpipes - M550i, 750i, M850i, X5, X6, X7

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.

Key Features

• Optimized Flow Design: Designed using advanced CAD modeling, each downpipe follows a refined flow path that maintains smooth, uninterrupted exhaust velocity for optimal turbo efficiency.

• Mandrel-Bent Construction: Crafted with smooth, full-radius bends to minimize turbulence and maximize flow—ensuring improved throttle response across the RPM range.

• Full 304 Stainless Steel Build: Constructed from corrosion-resistant, TIG-welded 304 stainless steel for strength, durability, and long-lasting performance.
  

• Direct Bolt-On Installation: Designed to align with OEM mounting points for a secure and stress-free installation.

• Integrated Flex Sections: Built-in flex joints reduce strain on both the downpipes and turbochargers during engine movement, increasing longevity and reliability.

• Reinforced Mounting Brackets: Strategically placed brackets match factory connection points on both the engine block and transmission, ensuring a solid and safe fit.

Our racing-grade downpipes are expertly crafted from premium stainless steel, using precise and standardized bending techniques to ensure optimal performance and thrilling exhaust note. Our downpipe pricing is U.S. market guaranteed. With an unwavering commitment to both price and quality, we adhere to a "customer-first" standard, ensuring that our products exceed expectations without compromise.

Note on CEL

Installing catless downpipes will trigger a Check Engine Light (CEL) since the DME (Digital Motor Electronics) detects the absence of an OEM catalyst. To resolve this without tuning, we offer a CEL Delete Kit. This kit includes O2 sensor spacers calibrated to BMW’s catalyst requirements, installing seamlessly into post-catalyst O2 sensor bungs to prevent the CEL.
