Hey everyone!
I have a 2025 BMW M340i and I’m looking to upgrade to a valved catback exhaust system.
I’m looking for something that sounds loud, deep, and aggressive when the valves are open, but can also be quiet when the valves are closed for daily driving.
For anyone who owns a 2025 M340i or knows a lot about BMW exhaust setups:
What brands or exhaust systems would you recommend?
Which ones sound the best without being too raspy or having annoying drone?
Can you manually open and close the valves with a remote or through the car’s driving modes?
Where’s the best place to buy one, and how much should I expect to spend?
Are there any compatibility issues with the 2025 model?
I’m mainly looking for a good balance between really loud when I want it and quiet when I don’t.
Would appreciate any recommendations, personal experiences, or sound clips. Thanks!
