We believe our rear exhaust combined with our mid-pipe offers the deepest sound and best performance of any other system on the market today.

    BMW's S55 motor is a modern marvel but one weak point, which Active identified is the entire cooling system for the intake which comprises the charge pipe, the aftercooler and the heat exchanger (or radiator). Finally there is a S55 aftercooler kit upgrade that is good enough to carry the Active Autowerke brand. Years of success in developing cars for motorsport has allowed Active to leverage its expertise to the top-mount charge air cooler on the F80 M3, F82 M4 and F87 M2 Competition. This aftercooler was made for the S55 and crafted using only high-grade aluminum to outperform the factory aftercooler in all situations from everyday driving to the toughest racing. The factory cooler was built to support a specific power target and environment. Many of you have increased the performance of the S55 which quickly overwhelms the stock cooler leading to heat soak and higher intake air temperatures which triggers the ECU to downgrade the performance until cooler air returns. Active's focus was not on a mass-market aesthetic add-on but a properly engineered improvement over the existing hardware. Active uses a tube-and-fin core designed specifically for the S55 and included turbulators to maximize the cooling efficiency in as small a package as possible. The end tanks are billet machined aluminum, not cast, folded, or bonded and ensure even distribution of the water throughout the internal aftercooler cores. High precision fittings, CNC machining, and TIG welding throughout ensures the highest quality construction to prevent pressure loss, and the lowest weight, in a bolt-on replacement. But Active also didn’t leave the aesthetics by the wayside as we dip the visible top of the aftercooler in a carbon fiber coating giving your installed cooling system a decidedly top market look to match the improved cooling performance. The Active silicone charge pipes for the F80 M3, F82/F83 M4 and the F87 M2 Competition improve the flow over the stock, compressed plastic pipes. The Active Silicone Charge Pipes allow you to maximize power on your F8X by securing all the boost that your S55 is making. These pipes replace the hot-side pipes leaving the turbos and into the top-mount aftercooler. The stock S55 charge pipes are notorious for developing hairline fractures at their plastic seams. These fractures or cracks are unnoticeable to the naked eye, but under boost pressure they open up leaking the desired charged air into the engine bay, and consequently can rob your S55 of it's full power potential. In addition, these leaks can trigger your S55's turbochargers to work harder to hit and maintain target boost pressure, potentially wearing them out sooner. Active uses silicone in this area because it will not contribute to heat soak and it's easier to mold for the correct clearances. Active uses a 5-layer silicone hose with all needed adapters and stainless hose clamps included. It fits perfectly with our CNC’d top-mount cooler.

    Fill Out Your Diffuser: Active Autowerke 90mm F87 M2 Exhaust Tips Let’s face it—the factory tips on the BMW F87 M2 are a bit of an afterthought. They’re small, they sit too far back, and they leave far too much of the ugly OEM piping exposed. If you’ve added an aggressive carbon fiber diffuser, those puny stock tips look even more out of place. Active Autowerke has the solution. These 90mm F87-specific tips are engineered specifically to fix the M2's rear-end aesthetics. By bumping the diameter up to 90mm, these tips provide the muscular, "filled-out" look the M2 should have had from the factory. Dial In Your Fitment One size does not fit all when it comes to style. These tips are fully adjustable, allowing you to choose exactly how much "poke" you want. Whether you prefer a flush, tucked look or an aggressive staggered setup that follows the curve of your bumper, these tips make it happen. To ensure they play nice with any aftermarket rear diffuser, Active Autowerke includes a 10mm exhaust mount bushing in every kit. This gives you the necessary clearance to prevent melting or vibrating against your expensive carbon fiber bodywork. Construction & Specs Available in a variety of finishes to match your build—from classic Brushed Stainless to stealthy Matte Black and sophisticated Carbon Fiber—each tip is built to withstand the heat and grime of daily driving while staying easy to clean. Tip Opening: 90mm (Massive upgrade over stock) Inlet Size: 70mm Overall Length: 119mm Engineering: Specifically designed to conceal internal OEM piping for a seamless look.

    Active Autowerke is proud to announce the release of the Signature F8X M3/M4 Exhaust System. This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, Active Autowerke has created a modular exhaust system that will provide enough flow to support power levels way above the stock S55. The stock S55 Midpipe is a dual-pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, AA's system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.

    Fill Out Your Diffuser: Active Autowerke 90mm F87 M2 Exhaust Tips Let’s face it—the factory tips on the BMW F87 M2 are a bit of an afterthought. They’re small, they sit too far back, and they leave far too much of the ugly OEM piping exposed. If you’ve added an aggressive carbon fiber diffuser, those puny stock tips look even more out of place. Active Autowerke has the solution. These 90mm F87-specific tips are engineered specifically to fix the M2's rear-end aesthetics. By bumping the diameter up to 90mm, these tips provide the muscular, "filled-out" look the M2 should have had from the factory. Dial In Your Fitment One size does not fit all when it comes to style. These tips are fully adjustable, allowing you to choose exactly how much "poke" you want. Whether you prefer a flush, tucked look or an aggressive staggered setup that follows the curve of your bumper, these tips make it happen. To ensure they play nice with any aftermarket rear diffuser, Active Autowerke includes a 10mm exhaust mount bushing in every kit. This gives you the necessary clearance to prevent melting or vibrating against your expensive carbon fiber bodywork. Construction & Specs Available in a variety of finishes to match your build—from classic Brushed Stainless to stealthy Matte Black and sophisticated Carbon Fiber—each tip is built to withstand the heat and grime of daily driving while staying easy to clean. Tip Opening: 90mm (Massive upgrade over stock) Inlet Size: 70mm Overall Length: 119mm Engineering: Specifically designed to conceal internal OEM piping for a seamless look.
