Some exhaust systems sound excellent, others could sound better. But if you fit a new exhaust on a BMW M, than it should be a total success. Because half of the job is done by the engine.
However, even matted to an M engine, some exhausts resonate properly, while others…well, don’t. This one here was caught on camera in Monaco, and has been paired with a 3.0 liter turbocharged, inline-6 engine, signed by the M specialists.
The powertrain produces 340 hp and 500 Nm of torque, which makes us understand that its sound should be more than good. In fact, it’s thrilling, no matter the exhaust system. That’s if you have enough time to listen to it, since it accelerates from 0 to 100 km/h in 4.9 seconds.
However, that AK47 Exhaust is more than a performer when you push the accelerator. It pops, bangs and crackles in the scariest way, as soon as you take your foot off the pedal. And that’s what makes it so special. It is, indeed, one of the loudest BMW 1M we’ve ever heard, if not the loudest.
But let’s keep in mind that the F1 tunnel in Monaco is one of the best resonating passages in the world, so this also amplifies the car’s excellent sound. Actually, when passing through that section, the BMW 1M sounds like a machine gun. I can only imagine it in wouldn’t be a good idea to own one in a war zone!
In the end, it’s clear that a top engine helps the exhaust perform best, and you can hear it in the clip below.
