S54 Intake Sound Question/Debate

[eforty6_m3]

If you have an exhaust, do not get a CSL intake.

You won't hear it.

With all due respect, I'm not sure I agree. I have a custom rear section and a Karbonious airbox and I can absolutely hear the gloriously intoxicating sound emanating from both ends (see what I did there), sooo.... 🤷♂️

I have the haimus box and it is worth every penny. WOT high in the rev range with the windows down is unbeatable. I have catless headers and an el diablo exhaust with catted section 1 as well. Not a terribly loud exhaust set up, but not quiet. I don't feel like it interferes with the intake sound too much.

Depends on what custom rear end. My friend has a Friedrich Titanium exhaust and that thing just completely overpowers the intake. I have a OM Scorza and I can hear my Airbox quite well. Recently I also removed the sound insulation on both sides of the firewall, now I can hear it even better 😁

+1 on the CSL intake. I had the Karbonius CSL intake on my car and loved every minute of it! Will be up for sale as soon as I’m allowed to and will come with install kit! 🤙🏻
edit: I’ll also add that the CSL intake is definitely loud, even with a head to section 3 exhaust. The difference in intake vs exhaust sound was very clear to me.

+1 on the CSL intake as well. Had an exhaust prior to install and thought to myself the intake wasn't as loud as I'd hoped. Then I went stock muffler (with high flow cats in section 1) and entire experience changed i.e. dial got turned to 11.

Oh, and if you are worried about smog, karbonius now makes an oem carbon intake that produces the sound and uses the maf; so that may pass California inspections if it’s just the plug in test.

It’s a visual inspection too. Some places might turn a blind eye but a big ass carbon fiber intake manifold is really asking for it lol.

Has anyone tried this? I would be curious as to the sound comparison to a CSL. It claims most of that without the tuning headaches.

Looks like the greedy pricks at IND raised the price a few hundred bucks on this combo kit.

Is better than stock plus Eventuri for sure, but I would say is not as loud, perhaps 80% of the volume. The sound is also a bit different as is higher in pitch and not as gutural as the CSL.

i have the two setups, what you posted above and an actual CSL Karb.

Yeah I can’t imagine the intake being mistaken for oem on our cars lol

It’s rough being a car enthusiast and wanting these sought after mods haha!

This was what I was looking for! After having the Karb CSL box on my car it was time to move to a setup that didn’t require removing every two years. Good to know the eventuri + oem style setup still makes ~80% of the noise

This was my path, Karb CSL to Karb OE + Eventuri. I do not regret it but I sometimes miss the deep growl from the CSL intake. Power wise is the same, and drivability is same as factory.

Does the gruppe M intake have any sound benefit? Seems like it should be similar to the eventuri except it has a snorkel to the front kidneys

GruppeM is louder than stock but not as loud as Eventuri (which is an open filter inside engine bay). GruppeM a better design power wise. But the thread is about more intake sound so not the design you’re after.

Do you have a link to this new intake?
