Sorry to keep asking, but please let us know your thoughts on this exhaust. It seems like people are only getting the 3 pipe center exit version. I wonder if anyone on this forum has or plans to get the quad tip version .

I’m itching to hear it as well. Good weather last weekend too.:)

I actually have the quad tip Tubi exhaust but we discovered dents and scratches on the exhaust tips upon install, in fact I’m working with Tubi to get the packaging/shipping damage sorted out as we speak. Will update once this has been resolved.

Shipping damage is never fun. Hopefully you get to enjoy it soon . We'd love to read your thoughts and watch vids of how it sounds in the various settings. I find it interesting that the Tubi people seem to prefer the sound of the quad tip one more. They've told me it sounds more refined, less raw.

Part 1 / 2

OK....after a few weeks of poor weather, I finally managed to take the car out for a spirited drive last week (and it doesn’t get more spirited than a burst up the Putty Rd).

I must first admit that I was drawn to the notion of replacing my OEM Race Exhaust, based upon a preference for the centre exhaust optics...rather the the standard single outer tips.

Together with my existing dramatic Koshi Carbon Rear Diffuser and ‘488 Style’ Koshi ’ Tail-light surrounds (which in my opinion gives the rear a lot more presence), I was pretty confident the centre exhaust would really complement these after market components and ‘complete’ the rear piece of my 4C puzzle.

Let me start with the with the actual purchase and service experience.

Time from order to delivery at my front door...just under 3 weeks. Considering the current global situation in relation to the many workforce and logistical constraints ....and that this is a low volume and made to order part...this is quite astounding !!

I was provided with Courier updates the moment it was despatched from their factory....nothing like counting down those days.

When the Exhaust arrived and I couldn’t resist the urge to open the consignment...I was very impressed with the well thought-out packaging and level of preservation and care taken by Tubi to protect all the parts in the carton . I can assure you...there is absolutely be no danger of any parts being damaged with the level of care and detail that TUBI went through in this respect.

Opening the box and inspecting the muffler, it was pristine....not a blemish and the chrome absolutely gleaming.

It struck me as a ‘real work of art’ and a credit to the Italian passion & artisanship that no doubt goes into the making of each of the exhausts they produce.

They also have a lovely touch of presenting the Remote/Fob in a branded TUBI ‘gift box’....magnifying the specialness and occasion of receiving the Exhaust.

The one area ‘missing’ of the package was the non-provision of any documentation relating to installation and user guidelines.

Thankfully, the distributor I purchased the unit from (Best Exhaust) were super efficient and requests to supply this and other queries that I had, were invariably responded to within the day (after they engaged directly with Tubi) and it was abundantly clear that TUBI value their reseller relationships and have a strong customer service ethos.

The Installation was performed by my ‘go to’ independent Alfa Specialist (Automoda) in Sydney...without any drama.....and now ready to rumble...

Part 2/2

Upon collection of the car...I was smitten by what I saw.

In my humble opinion, the rear still retains those sexy curves.....but it now presented an even bolder statement than before.

Those 3 tail-pipes are unmissable and your eyes are instantly drawn to them.

There is an innate sense of menace and purpose when those pipes are viewed....so...from an aesthetic enhancement objective...mission accomplished !!

My second admission is that I absolutely love/loved the ‘sniper’ like and rat-a-tat-tat shrill of the OEM Race Exhaust.

The cackles and those sharp, piercing wails upon acceleration...and those cheeky pops and farts always induced a grin...even if you were always ‘guilty as charged’ of disturbing the neighbourhood peace.

So, here’s the low down on the Tubi Central Exhaust.

Now...I don’t wish this to sound like a lament...but rather a very willing acceptance that the exhaust sound and a character of the TUBI is certainly markedly different to the OEM Race pipes.

Essentially, the TUBI Muffler has suppressed that wail and I have not any detected and pops or farts (in both Valve Open & Closed Moses) in the couple of drives that I’ve had.

However...the tone of the Exhaust is certainly deeper, throatier....but not in a raucous or obnoxious way. It just sounds and acts more ‘grown-up’.

There is also ZERO drone whilst cruising
and with the Valve ‘closed’....the volume level is at a very civilised level.

Flick the Remote (or use the App) to change the Valve to OPEN....and the difference in Decibels is immediately apparent. It feels like the noise level is 60-70% higher. With the Targa Top off...the Valve ‘always Open Mode’ is probably one to tolerate in small doses...

....but that’s the beauty of the 4 Tubi-Modes and the ability to align your Exhaust Volume and characteristic based upon YOUR preferences and general vehicle dynamics.

The TUBI exhaust controller has an in-built gyroscope and accelerometer (see pic) which directs rapid acceleration and de-acceleration and opens/closes the exhaust valve based upon some parameters entered into the TUBI App and then propagated by the Controller.

So to de-bunk any myths, the 4C ECU or TCU plays no part in the operations or dynamics of the Exhaust.

Talking of Dynamic, I have not noticed any discernible change in volume or behaviour of the TUBI when driving in Natural vs. Dynamic modes.

So....my next mission is to capture some audio grabs and post these...and hopefully this will provide better context to my written summation and I look forward to sharing this in the weeks ahead.

@fas74c Thank you for posting your impressions and experience! After you have more seat time, please comment on the two active modes you can select with the exhaust (e.g. how responsive and modifiable they are, whether they allow you to avoid drone while still being loud on hard acceleration, etc). Thanks again!

Thanks for the note Jagman...I now have worked out a cunning plan to record the Tubi Exhaust without the need for a GoPro or similar and have also downloaded a nifty app to allow me to edit the audio to segment and ‘label’ against mode.

Was hoping to go for a burn today...but (fun fact) Australia officially has the top 1-10 hottest towns and cities on the planet today and it’s a back to back 40c/100+f day in Sydney....so there’s Buckley’s of tormenting the 4C in this heat.

Not long to go until the Audio Clips are captured & posted

Mowed and whipper-snipped for an hour early this morning. Went inside for 10 minutes then came back to oven temps. You’re right, Ant, stuff that for a joke. The rest can wait. It’s down the club for lunch with my better half.
Hope to see and hear the exhaust soon enough. (y)

Finally...a little bit of downtime...the weather gods playing ball and my sense of resourcefulness coming to the fore.

Talk about Hacks....well...I certainly had to set my ego aside to let those driving behind me have their chuckle....but I was not going to be denied !!

No GO Pro...no worries.

OK...not quite the perfect outcome...but not the epic fail either. All-up..a kinda satisfactory outing that now has me yearning for more after my excursion and learnings from yesterday.

Having scoured the smorgasbord of our generation (which some people call “YouTube”) I stumbled across a “too good to be true” solution to my dilemma: how to effectively record audio of my new 4C TUBi Exhaust.

Hey presto....,apparently this is as easy as using your OEM iPhone (11) wired earphones which also happens to have an in-built microphone.

Hopefully this sets the expectation that the equipment used for the exhaust sound grabs is on the lower end of technology scale......but hey it was worth a crack and as you will have the opportunity to do so...I think is still worthy of showcasing some of the glorious sounds these beasts are capable of churning out !!!

Cut to the chase....this simply involved connecting the earphone/microphones to my iPhone...lobbing the IPhone into the boot of the 4C and using some masking tape to affix the cables and 2x earplugs/mics to the rear...draping this down until this was precariously poised just above the tips, pressing record on the App and voila !!

I’m sure this sight must have aroused the amusement or at least piqued the curiosity of those cars tailing me or stopped behind my 4C at the traffic lights.

Oh..yes... I did also splash out on a $7.99 App which allowed me to do some basic editing and management of the grabs.....I was now armed and dangerous.....to be continued soon...

...but in the meantime a little teaser:

Listen closely at the beginning to the birds tweeting....followed by the sound of a peaceful suburban street unashamedly being awoken by that glorious start-up...

She's got a definite grow, Ant. Nice. Can't wait to sit behind on a drive and hear it for real. Dario's just finished his system too so there'll be plenty to look forward to on the next run.

My excursion has allowed me to post a few clips which provides a taste, although perhaps not quite the sound that I heard from the Driver Seat.

One of my favourite drives is an outer suburban/semi-rural public B-Road on the northern outskirts of Sydney which has a nice blend of undulating, narrow a and tight corners and typically sparsely populated with traffic...to put the Tubi through it’s paces all in the name of research.

The stretch demands two hands on the wheel and absolute concentration, so I had the Valve Open consistently most of the time.
I’m happy to relay feedback on any of the audio segments if anyone has specific queries.

I managed to go on 3 solid runs (each around 3-4km’s) and recorded audio from each of them....and then took to extracting some of the more ‘interesting’ or aurally tolerable sections which were not to distorted from the cross air-flow pummelling those poor little ear pods.

What I have absolutely learnt with the iPhone earphone/microphone is that less is more. I had the earpod/mics probably 1-2 inches from the actual tips which in hindsight WAS way to close. If these things can pick-up a bird in tree tweeting 20 meters from the mic...I need to probably have these positioned just below the top of the lid/spoiler to reduce air movement across the mics as much as possible.

I watched a couple of Tuition Videos from a couple of GO Pro aficionados and there was much commentary on how acutely air movement/flow around the mic is detected. This unfortunately results in a flutter/buzz on the audio and which I think was made even more prevalent when doing my self/debriefing...that the exhaust backdraft/emissions was directly flowing across the mic...so the audio appeared fairly muffled.

My other observation is (and I desperately need Jim’s grey matter here)...is that the sound (tome) emanated at source ie right at the tops is perhaps different from that of 20 meters away or even in the drivers seat.

Tubi has an official audio/video clip...where the exhaust sounds quite preppy...very different to what my ears hear....however when I listen to the audio recording it is very similar in tone to my recordings.

Let me tell you... I do not quite understand it...as the TUBI Sound heard throughout the drive had a deep and broad sound...without a hint of ‘tinnymess” or metallic undertones..and I’m sure that would be apparent to other people/drivers who hear it.

What they a bloody apparent is that from standstill (think stop sign at intersection...look left and right...and then unleash).....the exhaust sound is just an orchestral orgasm !!

So, I’ve placed a few (10+) on Vimeo which whilst far from perfect does provide some delightful and viceroyalty appreciation of what we all know...and that driving the 4C is one helluva privilege and listening to those audio clips back again & again...however flawed they may be.....just wants to me to get in that driver seat and fire her up.

Wow Anthony,that would be the first really different sound I've heard from a 4C.I think it's totally different to one's I've heard on videos related to tubi.It sounds loud man, is it just the audio or does the note seem to be nicer when closed, ? Also your still running stock down pipe aren't you? Congrats mate well done.Ciao for now..
