Arguably THE BEST modification for your B46/B48. This muffler delete sounds too good to be a 4 cylinder! The combination of B48 and muffler delete surpasses all sound expectations from a 4-cylinder! Impressive direct-fit solution. With this new muffler delete you can transform the sound and driving experience of your 330 or 430. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage!

The ECS B48 muffler delete removes the heavy and restrictive factory exhaust muffler and replaces it with a high-flow, straight-through exhaust pipe. This adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. The muffler delete creates a noticeable increase in exhaust sound and more exhilarating turbo noise, without adding significant drone at cruising speeds. As an added bonus, our muffler delete shaves off 21.0 lbs., weighing in at only 7.0lbs compared to the OEM muffler at 28.0lbs!

Features and benefits:

Enhanced exhaust tone
Simple installation (with instructions!)
21lb weight savings! (Factory muffler 28 lbs, muffler delete 7 lbs!)
Tip adjustment capability ​
Slide farther on for left and right adjustment
Rotate for verticle adjustment
Good looking and durable 304 stainless steel construction
Heavy-duty fabricated sheet metal exhaust hangers
Dual staggered tip exhaust tips (integrated)
Installation and Support:

Installation is as easy as cutting, placing into position, and clamping!

Presenting our Turner Motorsport Performance Cat-Back Exhaust, tailor-made for your 4-cylinder F Chassis. Immerse yourself in an enhanced driving adventure as this meticulously engineered exhaust takes your B48-equipped car to exhilarating new heights. With an unwavering commitment to performance and quality, the Turner exhaust is crafted to unlock the full potential of your F chassis.

Experience a symphony of performance and sound, coupled with a visual upgrade through the quad exit exhaust tips that amplify the motorsport essence of your vehicle. Elevate your driving encounters with the Turner Motorsport axle-back exhaust - unleash the power, reveal the glorious sound, and capture attention wherever you go.

Incorporating their distinctive design principles, this exhaust produces a commanding, deep tone, revealing the bold personality of the revolutionary line of 4-cylinder turbo engines. Leveraging the factory valve control, the Turner axle-back ensures an exciting sound during acceleration, seamlessly blending the high-performance sound with daily driving convenience. Crafted from 1.25mm wall T304 stainless steel, Turner's exhaust boasts superior durability, corrosion resistance, and aesthetic appeal.

Designed with the customer in mind, the installation is a breeze, featuring a straight-forward slip joint and mounting locations. Your exhaust system includes all the necessary clamps and hardware for a hassle-free installation. Upgrade your f chassis with the Turner Motorsport axle-back and let every drive become a statement of power and style.

Upgrading the sound:

This exhaust allows you to turn up the volume and let the 4 cylinder boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a f chassis 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 B48 sound!

A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipe, your N20 can rev quicker, and deliver more horsepower and torque. Minimizing back pressure while remaining daily drive-ability was the goal of our N20 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install. After months of research and development, our engineers settled on a 3.5 diameter pipe which utilizes the least number of bends possible. However, the Signature N20 down pipe still fits easily into the OEM location, with a painless installation process. Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your N20!

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for BMW's with the N20 and N26 motors. This sensor is mounted in the catalytic converter in the rear most position. OEM replacement for BMW # 11787589122.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer.

The Dinan sport muffler is designed to compliment the 328/428 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dual 3.5" stainless tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The Dinan sport muffler is worth 3 point towards your Dinan badge.
