Dinan Makes BMW X5 M And X6 M Roar With New Exhaust System

Tuning / 3 Comments

It also unlocks an additional six horsepower.

We have huge respect for the BMW X5 M and X6 M, and we understand why they need to exist. The vast majority of BMW's profits come from its SUVs, most of which are built in South Carolina.

Both SUVs are devastatingly fast and able to get from 0-60 mph in less than four seconds. But because they need to be all things to all men, they also have to be refined, spacious, and luxurious. As a result, the already muted soundtrack (thanks to turbocharging) has to be dialed back to a point where it's socially acceptable, especially if you live anywhere near a Karen.

But now Dinan has three solutions that will make the X5 M/X6 M much, much louder. You can enjoy the results below. The neighborhood Karen will explode from sheer outrage. You might also want to keep an eye out for California cops.


For now, Dinan will offer the Axle-Back and X-Pipe options. The Full System will debut later, though it's unclear why. It doesn't sound loud enough to upset the law, and it unlocks an additional six horses and five lb-ft. Not that you'll notice such an insignificant power bump in a 5,455-pound SUV.

Either way, it allows the 4.4-liter twin-turbo V8 to unleash its full fury. Even though the engine produces 617 horsepower (in Competition guise), these SUVs never really feel special. Part of the reason why is the lack of noise on the inside. BMW pumps some noise in via the sound system, but even that doesn't help.

These vehicles just aren't engaging, so perhaps a louder exhaust is just what the doctor ordered. In case you're wondering, Dinan also offers louder exhausts for the X3 and X4 M models.


These exhaust systems can be installed on all 2020 to 2023 F95 and F96 models, both standard and Competition models.

Dinan keeps the stock exhaust valve actuators, which means the car will still respond to inputs from the M driving modes. Dinan also uses drone abatement technology to ensure it doesn't drive you nuts on the freeway.

The piping size increases from 3.14 inches to 3.26 inches. The twin secondary exhaust valves have a three-inch diameter, making them 30% less restrictive than the stock setup. The entire structure is made from 304 stainless steel.

Dinan only released pricing information for the Axle-Back option. It retails for $2,499 sans installation.
