Anyone tried a resonator delete on their BMW M340i?

If you’re considering a resonator delete for your BMW M340i, you’re not alone! This mod has become increasingly popular among M340i owners looking to enhance their exhaust sound. Here’s what you need to know about it:

What is a Resonator Delete?

A resonator delete involves removing the resonator from the exhaust system. The resonator is designed to cancel out certain sound frequencies, often resulting in a quieter exhaust note. By removing it, you can expect a louder, more aggressive sound from your M340i.

Why Consider It?

Many enthusiasts opt for a resonator delete for several reasons:

  • Sound Enhancement: A noticeable increase in exhaust sound, making it more aggressive.
  • Weight Reduction: Removing components could slightly reduce weight.
  • Performance Gains: Depending on other mods, it might help in improving exhaust flow.

Potential Downsides

Before you go ahead, consider the potential downsides:

  • Increased Drone: You might experience drone at certain RPMs, which can be quite intrusive on long drives.
  • Warranty Concerns: Modifying your exhaust system could impact your vehicle’s warranty, so check with your dealer first.

Installation Process

If you’re handy with tools, you can attempt this yourself. Here’s a brief outline of the process:

  1. Gather Materials: You’ll need jack stands, basic hand tools, and potentially a saw (if cutting is required).
  2. Lift the Car: Safely lift the car to access the exhaust.
  3. Remove the Resonator: Depending on your exhaust setup, this might involve unbolting or cutting. Ensure you have replacement piping if needed.
  4. Reinstall the Exhaust: Put everything back together, double-check for leaks.

Compatibility with Other Mods

The resonator delete can work well with other performance upgrades, such as a performance muffler or a full exhaust system. Many users report a more pleasing sound profile when combining these mods.

Conclusion

If you’re ready to give your BMW M340i a louder voice, a resonator delete might be the way to go! Be sure to weigh the pros and cons and consider seeking advice from others who have made this change. Share your experiences or ask for tips below, and let’s discuss!

From what I’ve read, a resonator delete can improve exhaust flow, which may lead to a slight increase in horsepower. But substantial gains might require additional mods.

Just to add on, there’s also the weight reduction factor. Every little bit helps, especially for track enthusiasts. Makes it feel more agile overall!

Good point, michaelmoore! While the sound is awesome, I can see how it can become tiresome on long drives. Finding a balance is key!

Indeed! It’s definitely a trade-off. The sound can be intoxicating at first, but could wear you down on longer trips. Something to consider before diving in.

Hey everyone! I’ve been thinking about doing a resonator delete on my M340i. Can someone guide me through the process?

Sure! First, you’ll need basic tools like a socket set, jack stands, and a cutting tool. Safety is key, so always wear gloves and goggles when working underneath your car.

Don’t forget to have a friend help you! The M340i can be a bit cramped to work on alone, especially when you’re aligning the pipe after the delete.

That’s a great start! Also, remember to disconnect the battery before you start working on the exhaust to avoid any electrical surprises.

I’ve seen some cool video tutorials on YouTube for resonator deletes. Would anyone mind sharing links?

Exactly! Using a rubber exhaust hanger can make it easier to align everything correctly.

Is a resonator delete legal? I’ve heard mixed opinions on this, especially if emissions are involved. Anyone experienced issues?

Honestly, it looks like a fun weekend project! Just try not to make your car sound like a lawnmower afterward. :smile:

In most places, as long as you maintain your catalytic converter, you should be good. Just check local laws before proceeding!
