The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Helical LSD puts the power to the ground and maximizes your vehicle's traction. A must for any car be it street, strip, or track. What exactly does an LSD do you ask? well without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have). An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.

The best way to gain a prominent advantage over the competition is to do it with the MFactory Metal Plate Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Plate LSD puts the power-to-the-ground and maximises your vehicle's traction. This 2-way differential will provide torque transfer during both acceleration and deceleration. This means that regardless of whether there is load (throttle) being applied to the differential or not, it will lock up during slippage. Ideal for those with track use in mind.

The best way to gain a prominent advantage over the competition is to do it with the MFactory Metal Plate Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Plate LSD puts the power to the ground and maximizes your vehicle's traction. This 1.5-way differential works similarly to a 2-way in that it provides torque transfer during both acceleration and deceleration. However, the advantage over a 2-way is that it requires less force to lock the differential. This means that it will allow for different wheel speeds, like when cornering. A 1.5-way differential is typically the best option for track or street use, as it keeps from having one tire skipping or dragging.

Gaining a prominent edge over the competition is now within reach, thanks to the MFactory Helical Limited Slip Differential offered by Turner Motorsport. This Helical LSD ensures a seamless and uniform distribution of power to your BMW's wheels, significantly enhancing traction whether you're on the street, strip, or track. It's an absolute necessity for BMW enthusiasts.

Curious about the LSD's role? Without it, your car essentially operates as a one-wheel-drive machine, delivering torque solely to the wheel with less grip. This is where the Helical LSD shines, as it allows both wheels to receive power by limiting the speed difference between them, in contrast to the open differentials found in most vehicles.

Key Features:

  • 30-Day Feel the Torque™ Money Back Guarantee: An industry-first assurance that enables you to experience the difference. Furthermore, it comes with a Limited-Lifetime Warranty, offering peace of mind.
  • Forged and Cryo-Tempered: Engineered to deliver exceptional durability and extended lifespan, ensuring it can withstand the rigors of even the most demanding challenges.
  • Advanced Shot Peening Technology: Enhances surface hardness, making it well-equipped to handle the shocks experienced in competition-level drag racing.
  • Maintenance-Free Gears: Bid farewell to the hassles associated with special fluids or rebuilds commonly required for plate LSDs. It's designed for a trouble-free ownership experience.
  • Lock-Free Operation: Ensures there's no adverse impact on steering response, delivering a smooth driving experience.

Break-In Procedure: For optimal performance, it's recommended to change the fluid after the first 3-400 miles of use.

Please note that any defects or warranty claims should be directed to Team MFactory.

Optimal power, performance and sound are the core values of our Active Autowerke BMW 328i exhaust system, designed to fit BMW 325i, 328i, and 330i E9X N52 models. A free-flow design and beefy 80mm dual exhaust tips allow 35% to 40% more exhaust flow than the stock BMW 328i exhaust system. The increased flow minimizes back pressure, resulting in substantial HP and torque gains. The system’s Brushed stainless steel construction also makes a bold visual statement, while also increasing durability. Factory-fit specifications are followed closely, yet AA's system allows 14lbs in weight savings as opposed to the factory BMW exhaust. This exhaust features the Active Autowerke Muffler and Noise Cancellation Chamber to assist in reducing/eliminating drone. Manufactured from 100% brushed 304 stainless steel, this clamp-on system is suited for the N52 owner looking to bring their BMW's performance to new heights. NOTE: This exhaust may not easily fit some of the XI (4WD) and Station Wagon Models - welding may be required for proper fitment of the exhaust to stock pipe. Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting points are highlighted in the instructions. Some models have a round tubular pipe that makes the installation seamless. Other models have an oblong shape and will require welding instead of clamping. KEY FEATURES: Fits BMW 325i, 328i, 330i Full 304 stainless steel construction with brushed finish 3" Mandrel-bent piping for optimum exhaust flow Straight through muffler design NCC (Drone Reduction) Dual 80mm Active Autowerke Signature tips, staggered Weight Savings *14lbs lighter than stock BMW exhaust* Designed to use existing factory mounts and hardware Fully adjustable mounting positions Fully adjustable tips Illustrated instruction manual Two year warranty Fits all E9X vehicles with the N52 engine. Requires cutting and welding of the stock system for fitment. Includes instructions for installation process.

Includes Recharge Oil (8 oz.) and Cleaner Spray (12 oz.). The recharge oil traps the smallest dirt particles, ensuring your engine is breathing clean air. The oil creates a positive magnetic charge with the filter's stainless steel mesh. This positive charge attracts negatively charged dust particles entering the filter, clearing them off the cotton and allowing for maximum airflow. The oil also contains a swelling additive for the cotton filtration media - this allows filtration media to collect small dirt particles that could harm your engine.

As Used on Project E92 335i
When adding boost to the N54 engine, it's important to consider effects throughout the rest of the system. Additional boost can overwhelm the stock BMW diverter valve system and lead to boost leakage, or boost spikes, and lost horsepower. With the factory components in place it's hard to maintain consistently high boost levels. Instead of the weak plastic components of the stock system, Active Autowerke uses a CNC-machined and mandrel-bent aluminum tube with a Venturi blow-off valve in place of the original diverter valves. The blow-off valve dumps overboost into the atmosphere for that distinctive turbo 'whoosh' sound. The single AA BOV is over-sized for the N54 application - taking the place of the two small diverter valves, and verified to handle over 600hp. With the BOV acting properly your turbos and other components are protected from compressor surge caused by excess pressure build-up.

We like the Active BOV better than other forms of diverter and BOV kits because it's tried and true - AA was the original turbo BMW tuners and their experience is second to none. That's why they took the time to engineer their kit to fit perfectly, using the OE-type connector to the throttle body, and high-strength silicone to the lower intercooler tube. Each connection is a tight, leak-free seal. The kit comes complete with the discharge tube, vacuum plugs for the stock hoses, and instructions. The tube is powdercoated in black and with a wrinkle finish for an OE appearance.

This item fits the following BMWs with N54 engine:
2008-2010 E82 BMW 135i 1M
2007-2010 E90 BMW 335i 335xi 335i xDrive

One major weak point in the N55 turbo plumbing is the stock upper chargepipe from the intercooler outlet to the intake manifold. The original N55 charge pipe is made from a weak plastic and can fail with even stock boost levels. The most common problem is a crack that develops along a seam where the pipe connects to the throttle body. Any crack here is bad as it creates a massive vacuum leak and the engine electronics will put the car into limp mode. If you don't want to be sidelined there is a very simple fix - the Active Autowerke N55 charge pipe.

This aluminum pipe is much stronger and more durable and nearly indestructable for the N55 application. It uses a CNC-machined factory-style connection and o-ring to the throttle body to ensure a tight and leak-free seal. The piping is a consistent 3" diameter for better flow and an improved throttle response. AA has included a raised boss with two ports should you choose to add a water/meth injection system later. The factory MAP sensor installs in the same location and the pipe is powdercoated black for a factory-type appearance.

With a stronger pipe you don't have to worry about the infamous chargepipe crack and lost boost levels and horsepower. All of the boost in the world is useless if it's leaking so using beefed up components in place of the weak factory pieces is the smart way to consistently high power output.

This item fits the following BMWs with the N55 engine:
2011-2012 E82 BMW 135i
2011 E90 BMW 335i 335xi 335i xDrive - Sedan

True performance, durability, and attractive weight advantages with innovative features places the Active Autowerke E9X BMW M3 exhaust in a class of its own. This system is constructed from 100% 304-stainless steel and features adjustable Active Autowerke double walled tips, making it ideal both for 2-door and 4-door models (also allows for cleaner fitment with diffusers).

This system uses factory style flanges making it a complete bolt on system that requires no cutting or welding. The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust.

The Active Autowerke E9X M3 Signature Exhaust System provides increase in horsepower, great sound and appearance making it a must for the true M3 enthusiasts.


Features:

  • Large 3-inch mandrel bent piping for maximum flow

The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Helical LSD puts the power-to-the-ground and maximizes your vehicle's traction. A must for any car be it street, strip, or track.

What exactly does an LSD do you ask? Without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).

An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off-road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.

Features:

Industry first, 30-day Feel the Torque™ money back guarantee and a Limited-Lifetime Warranty!
Forged and Cryo-tempered
Advanced Shot Peening technology for increased surface hardness
Designed to withstand the extreme shock loads of competition-level drag racing
Maintenance-free gears eliminate the need for special fluid or rebuilds associated with typical plate LSDs.
Lock-free operation ensures no adverse steering response.
**As a break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.**

Includes $500 core charge to be refunded when we receive your rebuildable core.

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application. A properly engineered solution for enthusiasts who want measurable gains while preserving OEM-level refinement and reliability.
