Bmw exhaust too loud on the highway

Here’s how to reduce drone, what causes it, and how to keep a better sound without ruining daily drivability.

Drone was greatly reduced, but still noticeable at certain highway speeds

You can look into j pipes for the helmholtz effect to negate the drone

There are some rpm calculators that you.

Exhaust drone is a resonance phenomenon where engine sound frequencies align with exhaust system vibrations, creating a monotone humming or buzzing that occurs at specific rpm.

I have had my 335i around 7 months now and i'm looking for something a bit extra in the sound dept

But i also want to keep everything legal and mot passable so don't want to go down the.

What is a good and easy solution to reduce drone at highway speeds

The exhaust currently sounds sporty, but civil, but when i'm cruising on the highway, i would prefer less drone.

The most effective solution for an exhaust drone is installing a resonator designed to cancel specific frequencies through destructive interference

Resonators work by creating sound.

Try to look beyond peak numbers, and notice the power it has made throughout the powerband

We should have some updated videos soon.

Only noticeable on low rpms but its not bad

The resonators tune the exhaust into something that isn't brutal to the ears, the mufflers quiets the whole thing down

So by removing it you're making the car.

If your bmw exhaust feels too loud on the highway, the problem usually is not just overall volume

That low, repeating cabin noise that settles in at cruising speed and makes the car.
