Ive had a 2016 M4 and just recently a 2020 m4cs and got used to a little burble/ noise. I just picked up a 2024 X5 40i and wanted to see what options I have. Anyone have any ideas that wont make it sound like Honda Civic with a hole in the exhaust? LOL

-Debated on doing just a resonator delete (Not sure if it would throw a CEL). Maybe the M performance exhaust but if its roughly the same sound, id rather go the cheaper route lol.

I have an M Sport exhaust and I am going in to have the baffled resonator removed, and replaced with an old performance (tube/bottle style) I took off my M Performance exhaust from my previous 4 series (when I did a resonator delete on that). When comparing the M Performance Exhaust for the 40i with the M Sport Exhaust, the different style of resonator seems to be the only difference visually (aside from what internals could be different in the muffler).

I will start a new thread to document what I do to change how my 40i sounds.

Catted downpipe install happening soon too.

These things should address the muted sound and just add a tad more aggression without being obnoxious.

I have an M Sport Exhaust (underneath, visually it has two inlets going to the muffler). Do you, too?

I bet, a resonator delete will pretty much sound the same as the M Performance Exhaust - and for $100, it’s worth the experiment. I wouldn’t think it would throw a CEL because a resonator is only addressing sound. Your cat is what would be related to a CEL. Plus - if it works out, you have like $3800 for something else lol.

Yeah I have the M sport exhaust.

LOL yeah I might just delete the resonator and hope for the best. I do want some popping but nothing crazy like the burble tunes out there

[gx5_027]

For sure. Burble tunes are lame. BMW 2018/2019 oem burble settings (for other models) are perfect.
Well, tomorrow I’ll have my resonator changed and will share.

Isn't the msport exhaust the same as the exhaust in the non msport package car?

Nein. There are three exhausts:
1.) Non M Sport (one inlet into the muffler);
2.) M Sport (two inlets into muffler) - seems that different countries have different types of “M Sport” exhausts - eg.) just because you have an M Sport 40i, doesn’t mean you have the M Sport Exhaust - best to check options on VIN and/or look underneath;
3.) M Performance Exhaust.

I have the M Sport exhaust for sale. I went mpe, but I can sell you the dual sport one.

Anyone know if a resonator delete on the 40i would make a lot of drone noise?

You'll hear it more in comfort than you normally would but it won't be "a lot of drone" at all. And on the highway, it definitely won't be like straight piping in which you would hear a lot of drone. It should be fine.

PS. I took my car to the shop for work on resonator, but the shop said they didn't have the skill to do it because the pipe is oval, not round. Going to go to a different shop when I have time.

If you decide to do it - let me know how it goes. Again, for $100 - you can't go wrong because you can always go back to stock if you don't like it. emerza

emerza In the past on my 4 series, I experimented with that open exhaust mod that everyone does (the golf t mod or whatever it's called - where the valves are always open), and I felt that caused drone on the highway and so I was quick to go back to stock with the exhaust valves working as they should. Removing the resonator, did not do that for me on that car - and I was also catless.

Ok cool....Im gonna wait till I get atleast 1k miles on it before removing it. Ill either praise or complain about it here after LOLOL


Thank you!

Resonator delete is barely noticeable and that from outside only. Not audible from inside the car.

Nahh, disagree.


It’s definitely noticeable.

Nope. You don't even hear it while driving

That's one weird excuse. Almost all exhausts have oval parts due to bends, attachments, etc. A competent exhaust shop can weld any piping. You are lucky that they told you that before they butchered your ride.

Sounds great!
Forgive me if I'm overlooking in this thread- what factory exhaust was on your car at the start?

Personally debating just a resonator delete w/ the M Sport exhaust for now.

Thanks!
