Over the years, the road takes a serious toll on your suspension. Pot holes, speed bumps, and road hazards all contribute to a sloppy, weak suspension. To give a better feel to your driving experience, change components as they wear to improve safety and ride comfort. One item to replace is the control arm. After years of service, the non-serviceable ball joints and other components can begin to wear out. Because some components cannot be replaced, the only solution is replacement of the entire arm. ECS Tuning has your replacement with this Genuine BMW made piece, a factory-direct unit that will restore your suspension. A tighter feel, less shake in the steering wheel, and more solid performance when hitting road hazards such as pot holes and bumps. Not only will you feel safe in your vehicle again, you can also feel comfortable. If replacing any part of your front or rear suspension, it is best to either do it in pairs (both left and right sides), or examine parts that are prone to failure. This will provide the most service life out of replacement parts and assure they are all performing properly. Skim through the suspension section of your vehicle model to see all those other parts that may need replaced.

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.
