Ok update on how the resonator delete went. Removed both resonators and got a custom x pipe. Really pleased with how it sounds. Cabin sounds the same but it’s a big difference when in sports plus mode with windows down. Biggest difference is revving in neutral. Burples are more frequent and much louder. Overall sounds more aggressive. Cold starts louder too but not so much it will bother the neighbors. If I don’t want that aggressive sound comfort mode sounds just like stock again.

Here is a video comparing stock sound with x pipe. https://youtu.be/XkbMkpb493M

I will add cold starts are much better now. I feel like sometimes this car is a bit too much of a sleeper and this def helps.

The X-pipe will add a few more horsepower through the design of the airflow/back pressure. A resonator delete will not.

A word of caution, doing the Dinan X-Pipe alone will barely make a difference in sound if at all unless you do it with the Dinan axle-back. An X-pipe is not the same a a resonator delete although both result with no resonators.

I went for the full Dinan system. Stupid money, but it's perfect for what I wanted which was a smooth engineered sound, none or minimal pops/crackles, no drone and most of all, I really wanted the quad exhaust look.

Do the resonator delete, don't waste your money on the Dinan mid-pipe alone, you will be disappointed. I have not heard many people complain of drone with the resonator delete, but these are people that usually like their exhaust to sound like a gun fight or sound like it is misfiring.

Now that I've done the resonator delete with custom X-pipe I'm very pleased with it. For a few hundred dollars it's a much better sound IMO. If there is any performance increase it's small enough I don't notice it. I do wish I had quad tips as those look awesome. But bang for your buck this seems like a no brainer modification if someone wants a meaner sound.

The pops and bangs are much louder in sports mode (other mods its just like stock). If you don't want pops and bangs, then you wouldn't want to do this.

Saw this after I posted, I totally missed page 2 of this thread. I love the look on your daughters face. Ah, the enthusiasm of a child. Soon she will be older like our significant others and just roll their eyes at us.

Glad you are happy. The sound of an exhaust is probably the most subjective thing from owner to owner. What sounds good to one person doesn't sound good to another and vice versa. Each one of these modifications produces a different exhaust note. For example, my full Dinan setup sounds much deeper than yours, but burbles are at a premium, reserved for a hard downshift. If you went resonator delete with straight pipes it would have sounded different too. I think I personally would have paid the $200 for just the resonator delete and straight pipe and lived with it for a bit and then if I decided to do the custom X, it is a simple as cutting into what they already did and plugging it in, I think, looking at the pics.

[Joe-BMW33]

Oh and yes, the increase in horsepower from my X-Pipe is like 2-5 hp, nothing you will ever feel.

[Joe-BMW33]

This look was more important to me than the sound, the sound is nice though!

[chuckles1313]

The quad tips are sweet looking!

Yeah I talked the custom exhaust guy for a bit before I made my choice. He was explaining how the straight pipes will give it a more deeper "wurble" sound vs with the x pipe. Since the x pipe allows the exhaust to mix from both cylinder banks it will sound faster and more sports like.

Now that I've driven for a bit I do think it sounds different in the cabin, but I like it. It's not overwhelming or annoying by any means and is only really noticeable when you're on the throttle. The car has so much power you can easily drive it and never get above 2k rpms so it stays very quiet.

I'm curious if I like my current sound, do they make just quad tips for the stock muffler?

[Joe-BMW33]

chuckles1313 no they don’t unfortunately, they are welded on to the axle back.

Considering turning off active sound design so you can hear your true exhaust.

How do you turn off the active exhaust sound? Only setting in iDrive 7 for engine sound I have found so far is one where you can set for it to match the drive mode, "sporty", "reduced", and "balanced". I believe that has more to do with the fake sound right? Drive mode seems to be the only thing that controls the valves on the exhaust from what I can tell.

[chuckles1313]

I know I have seen lots of posts with people zip tieing, welding, or removing the fuse to keep the exhaust valves open. I had hoped that setting I posted about earlier would control that but from I can tell it does not. I think that just controls the fake digital engine sound

I have a pre-LCI with iDrive 6. I used Bimmercode to deactivate ASD. On the LCI you have some choices to quiet it down, but it does not look like you have the option to kill it. I think you still need to code it out with Bimmercode.

For me, this let's me hear what my Dinan exhaust really sounds like, which I like. Also, by killing ASD, I find the audio system sounds much better as the speakers are not competing for bandwidth with the fake video game engine sounds. It's kind of like white noise behind the audio.

On the valves, I actually had the Dinan valve remote installed. I want to be able to open and close it myself independent from the car. I did not want to messing with fuses or zip ties. The Dinan remote makes the valves independent from the cars instructions. Well worth $250.

[Mandingo9]

I did resonator delete, for the money its a no brainer.

I very recently discovered that the settings on this screen DO have a direct control over the valves, which was a total shocker to me. I got a Dinan axle-back, res delete w/x-pipes on my '22 M550i and couldn't tell the difference between stock and the upgrades until we figured out that the selection on this screen was set to "Reduced". Changing it to "Sporty" opened the valves and it sounded the way it should.

Oh my gosh you must have been pulling your hair out trying to figure out what's going wrong.

So couple of follow up questions / thoughts. I wonder if that Sound Engine setting alters both the digital engine sound as well as the valves, but it must not fully change the valves. Because when I set the engine sound to sports mode, outside the car it def doesn't sound the same as when the car is in sports drive mode.

Also, I saw you have the XHP air intake. Does that alter the intake sound all the time regardless of driving mode right? Someone mentioned it can be annoying in comfort mode.

Yup, other than the obvious initial issue with the installation of the tips (which were sticking too far out), it was perplexing trying to understand why the setup didn't sound remotely like it should have based on all the reviews and video clips. I just though it only regulated the ASD, not the actual flaps.

I'm not sure, it felt to me as if the Reduced setting in the Engine Sound menu was enough to totally negate the extra exhaust note I was expecting in Sport Plus drive mode, despite all the hardware work done. Really felt like the flaps were fully closed when standing outside the car (I checked the sound revving in neutral in Sport Plus in both Reduced and Sporty sound modes).

Correct, the intake does alter the engine sound permanently regardless of the drive mode. All sorts of spooling whistles and whooshing noises, and the BOV can be heard pretty loud as well. I'd say the sounds are a bit reduced in Comfort only because the car shifts quicker and throttle response is a bit more relaxed, but comes alive the minute you step on it. I don't find it annoying at all, and with the windows up, the car remains reasonably well-insulated.

I don’t know if I’ll have this car long enough to justify doing it, but I like the deep tone the Dinan axle back exhaust gives the B58, too. The think I don’t like is that they only have one option for tips. They’re cool but they’re black. If they had a chrome or SS option, I’d probably pick that. But I could get over that. They don’t do quad tips for the B58, they do larger exit pipes with larger, black trapezoid tips. I’d pick the Dinan anyway, but it’s also the only one that will fit a non-M Sport model without cutting the bumper or fully replacing it. No diffuser to replace, it’s just one big piece.

[Osirisman]

Does anyone have a Remus axle back installed?

I installed mine last night and thought it to be pretty quiet, not much louder than stock with flaps open. Even with flaps open on the axle back it’s not a huge difference.

Kinda disappointed honestly, spending that much money for almost no improvement lol

Did you just do the axle back or did you do a full cat back? Meaning, are you still running the stock resonators?

No just the axle back, now hindsight probably should of gone full catback. May remove at least one resonator to give it a bit more noise
