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!

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.
