Your ABS sensors are the main tool that your ABS system uses when sending signals to the computer. If one of the sensors fail, a warning light will appear on your display alerting you of the situation. When an ABS sensor fails, the system no longer operates. When a time comes when you are expecting the system to kick in, it will not, a dangerous situation if the driver is accustomed to it. Replace your worn out or broken sensors and make sure that everything is up to the task of snow, ice, and wet roads.

The Ate DOT 5.1 fluid is a low viscosity formula for modern ABS and DSC systems. BMW recommends low viscosity brake fluid for all chassis beginning with the E60 5-series. Low viscosity (LV) is a thinner fluid that works better than a normal fluid in the small channels and passageways in the ABS/DSC pump. Using the heavier fluid will result in a delayed response to ABS and DSC activation and a spongy feel in the brake pedal (only during ABS stops). A low viscosity fluid replacing DOT 4 fluid. Boiling point - Dry 265°C (509°F) / Wet 180°C (347°F) Sold per liter (1,000mL).

The S63 and N63 twin-turbo V8s are world-class powerplants, but they’ve got a breathing problem. From the factory, your BMW X5M, X6M, 550i, or 650i is suffocating under massive backpressure caused by restrictive, bulky catalytic converters that trap heat and kill momentum. If you want real power, you have to let those turbos spin. Active Autowerke’s Signature High-Flow Downpipes are the ultimate "no-compromise" upgrade for the serious BMW enthusiast. Hand-fabricated in Miami, these 3.0" downpipes utilize GESi G-Sport Ultra High Output technology. You get the raw performance and rapid spool of a track setup with the refined, odorless experience of a daily driver—and most importantly, no Check Engine Light. Why These Downpipes Belong on Your BMW: Turbo performance is all about the pressure differential. By clearing the path behind the turbine wheel, you allow the turbos to work significantly less to produce significantly more. Instant Turbo Response: Experience a massive reduction in lag with quicker spool-up and instant throttle tip-in. Massive Power Ceiling: The 4.5" GESi 400-cell cores are rated for 500hp to 850hp, ensuring they won't become a bottleneck as you climb the ladder of modifications. Clean & Odorless: Forget the "gas station" smell of catless downpipes. These proprietary precious-metal catalysts keep the air clean and your cabin comfortable. Hand-Built Precision These aren't mass-produced units. Each set is TIG-welded 304 stainless steel with cast upper V-band flanges for a factory-perfect, leak-free seal. Because Active Autowerke builds these in-house, the fitment is surgical—designed for a straightforward bolt-on installation with no cutting or welding required. Turner Fitment Note: To guarantee 100% accuracy for your build, please provide your VIN at checkout. Note: These are F-chassis specific; G-body vehicles with the N63B engine require a different configuration. Core Features: No CEL Guarantee: Optimized for catalytic efficiency to keep your dashboard clear. 49-State Legal: EPA Registered and fully OBD2 compliant (Excludes CA). Built for Heat: Rated to withstand up to 1,500°F and reaches operational efficiency in just 9 seconds. Legendary Durability: 304 stainless substrate is furnace-braised to the mantle for maximum vibration resistance. Warranty Protected: Includes a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Technical Specs: Material: TIG-Welded 304 Stainless Steel Tubing: Full 3.0" (76mm) Mandrel-Bent Piping Catalyst: GESi Ultra High Output (400 CPI) HP Rating: 500hp - 850hp Lead Time: Custom made-to-order (Approx. 2 weeks) *A Note on Burble Tunes: We love a good exhaust crackle as much as anyone, but "aggressive" burble or pop maps physically destroy catalytic substrates. Use of such tunes will void the warranty on the GESi core.
