Turner Motorsport BMW Axleback Exhaust

Get rid of your heavy and restrictive factory exhaust and upgrade to a lightweight free-flowing performance exhaust!

If you are looking for the perfect combination of sound, quality and pricing, this is exactly the exhaust you are looking for. Its time to upgrade from your old and blocked up factory exhaust or the leaky exhaust that was welded up by the owner before you. Your going to love the new sound of your N52 with our new Axle Back Exhaust! The tone and character of this exhaust was designed with the true enthusiast in mind.

This simple yet effective axle back turns your N52 from boring, into a recognized sports car. N52 cars have fantastic styling and can be fitted with exterior mods such as wheels, coil overs, carbon, the works. With such a great looking chassis you need a great sounding exhaust. With not only performance but sound in mind; this exhaust features a deeper tone with added volume to get a sound that will impress your fellow enthusiasts.

Our Turner N52 exhaust slips over your factory exhaust right after the secondary cats to keep your car in full compliance with emissions. After your secondary cats the exhaust feeds into a single 3" exhaust pipe which replaces the factory resonator for the best flow and transformation of sound. The large 3" diameter exhaust flows into a full 3" muffler that was designed in-house for the best performance and dampening to achieve the great tone from your N52. In order to compensate for the factory oversized muffler and resonator, this muffler was designed to provide a specific frequency and output that Turner was looking for.

PRODUCT DEVELOPMENT

Our Turner N52 Axle Back 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.

Our Race Inspired exhaust deletes the rear mufflers in the F10 M5 to allow more of the exhaust sound to be heard. We love our M5 but it's just too quiet so we looked at ways to get more of the stock exhaust to be heard. After evaluating the stock exhaust layout it was easy to see that removing the rear mufflers would accomplish what we wanted. But cutting the mufflers off is just the beginning. We then had to develop a set of pipes and design a set of tips that fit perfectly and also looked right at home on the M5 super sedan. And these M5 muffler delete pipes are the finished product.

Our axle-back exhaust is made from a 304 stainless steel tube in the same diameter as the stock exhaust and with mandrel bends for unimpeded flow. It fits with the stock hangers and is clamped to the stock exhaust pipes once the mufflers are cut off. And the entire installation can be done in about an hour with the exhaust on the car. With factory clamps, you can easily reinstall your stock mufflers or a set of Corsa Performance mufflers at any time. Our tips are also stainless in a perfectly proportioned 89mm (3.5" diameter). They fill out the rear bumper valence perfectly - not too small like stock and not boy-racer large. Tips are available in mirror silver or brushed aluminum..

The final result is that removing the stock mufflers really lets the M5 V8 sing! With the mufflers and flapper valves removed the sound on start-up is scintillating. The sound from the S63TU engine is robust and intoxicating - it just needs to be heard! From outside, the muffler-delete exhaust makes the car seem all the more impressive. From the burble at idle to the roar under full throttle there is little doubt that this is a proper M car. Inside the car during normal driving the sound is not changed much thanks to the Active Sound Design system. It's a little louder but not intrusive or irritating. Around town the car sounds much like stock but just a touch louder. The exhaust pops and burbles more with each downshift. On the highway at 70-80 cruising speeds it's as quiet as a muffled exhaust. We tried to get the exhaust to drone but only experienced it at low speeds in a high gear (i.e. - lugging the engine) which we normally wouldn't do.

Our Race Inspired M5 exhaust is perfect for enhancing and accentuating the stock sound. It lets more of the M5's soundtrack come through without extensive exhaust modifications. If you want to enjoy the M5's sound more, think of this as its volume knob turned up.

This item fits the following BMWs:
2012+ F10 BMW M5

Let’s be honest—what’s the point of owning a B58-powered BMW if you can’t hear it?

Upgrading the sound:

Our 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 a S55 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 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!

How our axle-back is designed:

To create a axle-back exhaust for this incredible vehicle the upgrade happens right after the factory secondary cats. We replaced the factory components with dual 2.5" free-flowing stainless steel piping. The twin pipes make their way through the center and rear of the car without the center muffler 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 F87 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and oe-style hangers the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Quad 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.
