Upgrading the sound:

Our exhaust allows you to turn up the volume and let the B46/B48 boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B48 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 B48 sound!

How the cat-back is designed:

To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. Turner replaced the factory components with oversized 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, this exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is Turner's signature B46/B48 muffler with a 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 3.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

Optional OBD Plug-In:

The factory-valved muffler is not only controlled by different driving modes like comfort, sport, and sport plus but the RPM also plays into whether the valves are opened or closed. If you are looking for a solution to define whether your exhaust valve is fully opened or closed then you should look into adding an OBD plug-in that features Bluetooth valve control from your phone. During testing, the best way to choose whether your valve is open or closed for your sound preference is through an OBD-linked application on your phone. Included in this kit are optional OBD extensions to not only gain diagnostic function but also gain the ability to influence widgets on your vehicle such as valve position on your valved muffler.

From stealthy early-morning starts to unleashing your exhaust’s full roar on demand, the ECS Remote Vacuum Exhaust Valve Control Kit gives you total control over your car’s voice—whenever and wherever you want it.

Among the many reasons enthusiasts flock to the S58 is its unmistakable exhaust character. BMW’s twin-turbocharged inline-six delivers a fierce, motorsport-inspired snarl at wide-open throttle—yet the factory mid-section muffles much of that personality. The stock resonator and restrictive flow path tame the soundtrack, muting the aggressive tone your G8X M3/M4 is capable of producing.

Turner Motorsport set out to change that. Their Resonator Delete transforms the factory system with a direct bolt-on mid-section engineered to free both sound and performance. By removing the bulky OEM resonator, integrating a true x-pipe, and shedding roughly 5 lbs of unnecessary weight, this upgrade enhances exhaust scavenging, sharpens throttle response, and unleashes a deeper, more engaging tone. Best of all, it retains full compatibility with the OEM downpipes and valved rear muffler—delivering a noticeable sound improvement while preserving factory functionality and easy reversibility.

Features:

Deeper, more aggressive exhaust note with added character and minimal drone

X-pipe design promotes efficient exhaust scavenging for improved flow

Maintains OEM valved muffler operation for factory refinement

Approximately 5 lb weight reduction vs. the stock center resonator

Brushed 304 stainless steel construction with clean TIG-welded seams

Design:

1.25 mm-wall brushed 304 stainless steel tubing

76.2 mm (3") diameter

304SS sleeve-style and Accuseal clamps with slip-joint adjustability

Installation:

Installation is as easy as cutting your factory exhaust, raising the new center resonator delete into position, and clamping. Click HERE for Installation Instructions. Product Development:

Our Resonator Delete/X-Pipe was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including 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.

If you are bored of E53's factory exhaust and want to hear more of your German V8, Our E53 muffler deletes are the perfect solution! We developed a simple yet affective way to transform your exhaust without breaking the bank. Our E53 muffler delete system is a slip fit exhaust option that you can install in your own garage with just hand tools.

Over the years your factory muffler gets filled with deposits and turns almost rock solid (knock on them, they no longer sound hollow.) The build up of deposits add weight and can even reduce flow causing a restriction and build up of unwanted backpressure. You can now remove the large restrictive suitcase mufflers and a install light weight and free flowing exhaust that looks just as good as it sounds! To ensure the best driving experience the factory center resonator is left alone to ensure the least amount of drone while still getting that low rumble exhaust tone.

There are few exhaust options on the market for X5's and the ones available are expensive. With the muffler delete pipes, simply cut in front of the mufflers and get the heavy suitcases off your car. Your new muffler deletes feature dual 2.5" exhaust sections and come with the option of brushed aluminum or mirror chrome dual 3" tip exhausts that fit right at home in your factory rear valance.
