BMW Catback Exhaust Systems

If your exhaust system has been damaged or you want to restore your exhaust system back to stock from an aftermarket system, this M Performance exhaust system from BMW is the factory performance exhaust that came with the car from the dealership.

Genuine BMW M Performance Muffler System

E46 M3 Performance Valved Cat-Back Exhaust:

The wait is finally over, if you have been driving your E46 M3 around with a stock exhaust or are looking for your final exhaust setup we have you covered! Welcome to the world of ingenious designed exhausts that can meet your every driving need. Our new E46 M3 catback Exhaust is a stunning example of both engineering and art with sounds to please your ears and a sight to remember. Our catback is a lightweight and free-flowing exhaust that features two independent valved mufflers and a brilliant mounting system that is a pleasure to install and easy to perfectly dial in the exhaust fitment. Weighing 19lbs or less than your factory exhaust, featuring mufflers specifically designed for the S54 this exhaust is able to provide two completely different driving experiences.

With the exhaust valves closed the refined driving experience will blow your mind; while daily driving with closed valves there is a perfect bump in volume over the factory exhaust which allows you to hear and feel your rpms with a smooth exhaust note that shows your true passion for your iconic vehicle.

Now on to the real action, what you have always wanted but never wanted to commit to. Some days you just want to put the pedal to the floor with unlimited amounts of exhaust volume with your high revving 6 cylinder. Here is your opportunity to unleash the pure sound of your S54 while having the choice to change back to a respectable volumed exhaust. With the valves open this exhaust is an absolute symphony. Starting off from a stop with the valves open there is a significant increase in volume over the valves closed. When entering in to the 2000 rpm range you begin to experience the slightest taste of how satisfying the exhaust is going to sound. As you approach 4,000 rpms and higher you now have started to open up the can of worms, you can feel the free-flowing path of the exhaust with limited to no resistance, far superior to the factory exhaust. Anything after 6500 rpms is an absolute statement of exhaust. Over 6500 rpm is a sonorous note that lives rent free in the enthusiasts mind that can make a believer out of anyone who doubted the capable E46 M3. Once you are done having your fun and have experienced your S54 more than you ever have all you do is make one button click on your valve controller and you are back to high class and refinement. Truly the best of both worlds and a school girl giggling experience anytime you want.

Upgrading the sound:

This exhaust allows you to turn up the volume and let the S55 roar a hearty exhaust tone. Let's be honest, what's the point of owning an S55 if you're not going to upgrade the exhaust? Turner's 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 twin-turbo S55 sound!

The F87 M2 Competition & M2 CS models are simply amazing to drive; don't let road debris keep you from enjoying the moment. These cars have so much packed under the hood to get you this experience it causes the oil cooler to be placed face-down to the road. This makes the cooler an easy target for impact, which can prove catastrophic as the stock belly pan is designed from a flexible plastic material. We've heard stories of small branches, scrap pieces that fell from trucks to large ice chunks impact the cooler immediately draining the car of its oil. If you don't catch this right away this could cause serious internal engine damage due to oil starvation.

Turner's in-house engineering designed a skid plate to protect your oil cooler from these unfortunate situations while maintaining factory aerodynamics and fitment. The idea was to design something much stronger yet that still keeps the weight to a minimum. The Turner skid plate weighs slightly more than the plastic OE piece, making the Turner plate the lightest metal option on the market. This skid plate requires no modification and mounts using the existing factory hardware. Using a trim seal to press against the oil cooler allows the airflow to pull heat from the cooler the same way the OE belly pan was designed.

Features:

No cutting, drilling, or modification required 1/8” 5052 Aluminum skid plate construction. 10 Ga 5052 Aluminum side pieces to save weight. Increased ground clearance. Integrated frame-mounted support bracket for maximum strength. Included bulb seal maintains oil cooler efficiency. Retains factory air duct for oil cooler. Maintains wheel liner mounting positions.

B58 Performance Valved Catback Exhaust - F30, F32, F33, F36:

Still have the factory exhaust fitted to your B58? You don't know what your missing. Free up lost performance with a new full cat-back exhaust complete with factory valve control!

The B58 engine earned the badge "Worlds 10 Best Engines" four times as of 2023. In 2016 the single turbo straight six found its way to the leaderboards for the first time and followed up in 2017, 2019, and 2020 staying on the charts as one of the best engines in the WORLD.

Our new cat-back exhaust is designed to take out restrictions, maximize flow and give your B58 a signature exhaust note that will excite you on every drive. From the factory your vehicle comes equipped with a combination of three mufflers and resonators that do a great job of silencing the exhaust and restricting flow. There is a center muffler(one restriction), rear section resonator(two restrictions) and a bulky muffler(three restrictions!). With all of those stop gates how do you expect to get the maximum performance out of your vehicle, you simply cannot do so. Lucky for our in-house engineers you no longer have to deal with the quiet and limiting factory exhaust.

To create a cat-back exhaust for this incredible engine the changes happen right after the downpipe. We replaced the factory oval pipe 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 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. Dual 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

B58 Engine Design:

BMW's first mass produced turbo charged engine, the N54 took the world by storm opening a whole can of worms in the car industry and aftermarket community. A new era of motors were created with the new B58 roughly 9 years after the N54 had been tested and pushed to its limits along with its single turbo companion, the N55. In 2015 the modular engine family was created and the B58 was released into the wild to set a new standard in performance and reliability. Turning back to their roots the B58 engine features a closed-deck engine design similar to the N54 that allows a massive increased in boost pressure capacity and heightened compression ratio. Thought the B58 is similar in weight and size to its predecessor, the new modular engine makes considerably more power right off the rip. With the new block design heat management has been upgraded to reduce the affects of heat cycling to slow the rate of cooling and prevent engine components from failing due to rapid cooling. Just like the N55 the B58 comes fitted with dual vanos, valvetronic and a single twin scroll turbo. Just 8 years experience of this motor we can all agree that the B58 looks like it could be the future of motors to come. This tunable engine has been tested up to 1000hp with the stock block and hosts a platform for the community to break into a whole new class of attainable "supercar killers".

Turner Aluminum Charge Pipe - F3x B58:

- Click HERE for Installation Instructions -

The factory B58 charge pipe is made from plastic to reduce weight and manufacturing costs. While this is great for the production line and the sticker price, it doesn't hold up well as the engine ages or in the case of increased power.

Replacing the weak plastic stock part with a solid aluminum one like this will ensure proper functionality under higher levels of boost and eliminate wear caused by the heating and cooling of plastic pipes. You can also safely turn up the boost on your B58 once this kit is installed, and not worry about the problematic factory piece.

Whether you have a stock car and are looking for improved throttle response and peace of mind, or a high boost monster in search of reliability in your big horsepower build, this charge pipe is the solution you’ve been looking for!

Design Features and Benefits:

The upper pipe is constructed from 6063 aluminum for increased durability over the factory plastic charge pipe. Can withstand higher boost pressures while offering OE-like fitment.

Billet CNC throttle body flange for OEM fitment.

Black powder coated for exceptional durability and corrosion resistance.

Lower pipe is constructed of 4-ply reinforced silicone hose and a 6061-T6 black anodized aluminum coupler to retain factory fitment to the turbo.

Silicone provides a smooth transition from turbo outlet to the upper aluminum pipe. The silicone also provides good wear resistance wear the charge pipe is in close contact with the turbo inlet and coolant hoses.
