Introducing our Turner Performance Cat-Back Exhaust for your G20 M340! Precision-crafted exhaust that elevates your driving experience with a new level of excitement. Designed with our commitment to performance and quality, this exhaust is meticulously engineered to unleash the true potential of your M340. In tandem with performance and sound, our cat-back exhaust enhances the visual aesthetic with upgraded quad exit exhaust tips that complement the overall motorsport nature of the M340 and replace the fake factory exhaust tips. Upgrade your driving experience with our cat-back exhaust for your M340! Unleash the power, bask in the glorious sound, and turn heads wherever you go.
Using our signature design principles this exhaust is crafted to deliver a deep, authoritative tone that reveals the true rowdy attitude of the M340. Designed to utilize the factory valve control our cat-back provides an exhilarating sound during acceleration without compromising the daily driving amenities. Our exhaust is manufactured of 1.25mm wall T304 stainless steel for superior durability, corrosion resistance, and aesthetics. Designed with the customer in mind it features a straightforward bolt-on installation utilizing factory slip joints and mounting locations and includes are clamps and hardware necessary for installation.
Upgrading the sound:
Our exhaust allows you to turn up the volume and let the B58TU boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B58 if you're not going to upgrade the exhaust? Our signature muffler design allows you to transfer the exhaust valve from your factory system directly onto your new Turner system. The Turner exhaust signature muffler design allows for two flow paths that change both tone and volume. With the vehicle in eco or comfort mode, the valves remain closed, with the closed valves the exhaust system allows the gasses to flow through the muffler toning down the volume and giving a more refined exhaust note. While in driving modes sport or sport+ the valve opens and the flow path changes to a "straight flow path" essentially turning into a straight-piped exhaust for the least amount of restriction and the most amount of B58 sound!
Upgraded aesthetics:
From the factory, the G chassis comes equipped with fake or imitation exhaust tips, our Turner exhaust allows you to remove the imitation tips from the vehicle and sport a set of 4 true exhaust tips giving that upgraded motorsport styling.
How the cat-back is designed:
To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. We replaced the factory components with our full 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep the flow to a maximum! With smooth mandrel bent transitions our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature B58 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Quad 3.5" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.
Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain hole can be used with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Let’s be honest—what’s the point of owning a B58-powered BMW if you can’t hear it? The factory M340i and M440i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone the B58 engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged inline-six sound without the cost of a full cat-back system.
Engineered and manufactured in-house, this system replaces the factory rear muffler with a free-flowing, TIG-welded 304 stainless steel setup designed to enhance tone, reduce weight, and maintain OE-level fitment and quality. At the front, 3" primary tubing mates seamlessly to your factory midpipe using a durable stainless steel sleeve clamp. At the rear axle, the primary tubing transitions to dual 2.5" adjustable tailpipe sections for a clean, yet aggressive look. These tailpipe sections merge to quad outlets, designed for compatibility with our selection of 3.5" exhaust tips, allowing you to tailor the system's appearance to your liking. Accuseal-style, slip-fit joints allow for easy adjustment, ensuring perfect tip placement inside the factory rear diffuser. The result?

G20 models are simply amazing to drive, paired with a B58 engine, the M340i will leave you speechless; don't let road debris keep you from enjoying the moment. BMW engineers positioned the oil cooler quite low under the car, positioned horizontally - an aerodynamic design that creates a vacuum force while driving, drawing heat from the oil cooler. The issue some of the vehicle owners have experienced is road debris from small branches to chunks of ice that have impacted the OE belly pan hard enough to crack the oil cooler draining the car's oil rapidly. Being one of the lowest points of the car, even a close encounter with a parking block can mean the end of the road for the factory belly pan - and oil cooler. Damage to the belly pan means reduced cooling, which can result in dangerously high engine temperatures. Once the belly pan is damaged, there is no longer any protection for the oil cooler, meaning damage to the cooler and a catastrophic loss in oil pressure may be right around the corner.
Designed using 8 gauge 5052 aluminum, this skid plate kit offers plenty of strength to protect your oil cooler and transmission. We also made sure this would be an easy, reversible upgrade by maintaining OE mounting locations and hardware that requires NO cutting or modification to your vehicle for fitment. Our engineering team also felt it was important to maintain some of the cooling features the BMW engineers spec'd out such as having a trim seal to fit snugly against the cooler edges to create the same vacuum cooling effects as stock.
Features:
No cutting, drilling, or modification required
1/8” 5052 Aluminum skid plate construction.
10 Ga 5052 Aluminum side pieces to save weight.
Maintains factory aero design, while offering improved ground clearance compared to OEM.
Integrated frame-mounted support bracket for maximum strength.
Access door for oil pan drain plug.
Maintains wheel liner mounting positions.
Stainless mounting hardware included.
Made in the U.S.A

BMW's are notorious for their failure-prone control arm bushings. The pliable rubber bushings, present even in M performance models, allow substantial movement of the front wheels to enhance everyday driving comfort. However, they also permit significant alignment changes, leading to a disconnected and numb road feel that detracts from a confidence-inspiring driving encounter. Over time, the fluid-filled rubber bushings succumb to fatigue and cracking due to continual deflection and ozone degradation, ultimately resulting in the leakage of damping fluid and complete failure.
For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available! Our experience with spherical control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).
The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise. We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment. What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.
In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.
Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set, and are available (T599476) if you would prefer that option.

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.
Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.
Features & Benefits:
Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:
Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:
Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

BMW engineers positioned the oil cooler quite low under the car, positioned horizontally - an aerodynamic design that creates a vacuum force while driving, drawing heat from the oil cooler. The issue some of the vehicle owners have experienced is road debris from small branches to chunks of ice that have impacted the OE belly pan hard enough to crack the oil cooler draining the car's oil rapidly. Being one of the lowest points of the car, even a close encounter with a parking block can mean the end of the road for the factory belly pan - and oil cooler. Damage to the belly pan means reduced cooling, which can result in dangerously high engine temperatures. Once the belly pan is damaged, there is no longer any protection for the oil cooler, meaning damage to the cooler and a catastrophic loss in oil pressure may be right around the corner.
Designed using 8 gauge 5052 aluminum, this skid plate kit offers plenty of strength to protect your oil cooler and transmission. We also made sure this would be an easy, reversible upgrade by maintaining OE mounting locations and hardware that requires NO cutting or modification to your vehicle for fitment. Our engineering team also felt it was important to maintain some of the cooling features the BMW engineers spec'd out such as having a trim seal to fit snugly against the cooler edges to create the same vacuum cooling effects as stock.
Features:
No cutting, drilling, or modification required
1/8” 5052 Aluminum skid plate construction.
10 Ga 5052 Aluminum side pieces to save weight.
Maintains factory aero design, while offering improved ground clearance compared to OEM
Integrated frame-mounted support bracket for maximum strength.
Maintains wheel liner mounting positions.
Stainless mounting hardware included
Made in the U.S.A
