23' V4S- Full Akra or SC-S1 slip on

two exhaust systems below

SC slip on - SC-Project - Titanium half system 2-1 with S1 exhaust - DUCATI PANIGALE V4 - V4S

AKRA full - https://www.ducati.com/us/en/accessories/ACC011056


My question is it worth it to spend the extra $4000 for the full akra under belly system over the SC project slips? If so , How much more power are the headers going to provide?

Looking for the most power out of the v4 platform as i will be adding a sprint filter & brentune stage 2 , was wondering if the slip-ons would a better bang for the buck as i would save $4k to add to other modifications as well.

I prefer louder bikes & after countless videos the sound over a microphone doesn't do ether system justice so would be nice to hear first hand from those who have had any of the above systems.

Total sound? Power? Crisper sound? ect.

Leaning towards the SC-S1 but i want to see if i can be convinced otherwise.

Any input helps.

Thanks!

SC exhaust not good, also Brentune is trash

$4k has varying levels of significance based mostly on your income.

Any power increase from the headers would likely be within the margin of error of the dyno. They would be lighter.

You may want to do some research on the Brentune. I think there are better options, ESPECIALLY if you run into problems.

For a slip-on package, if that's all you're willing to spend for, it's hard to overlook the Termi. Comes with a tune, sprint filter and sounds good. I liked the sound a bit more than my full under belly Akra system. The Akra is louder and more akin to a race exhaust while the Termi is a bit deeper and has a good tone.

Why is SC exhaust not good and along with brentune. More info would be helpful to make my decisions . Thanks

Thanks for the feedback,

As for the full system headers weighting 4 lbs less than stock and only providing minimal gains, I’d stick with the slip on.

I think I might go with the SC slip as it’s more my style and sound preference. As for tuning which tuner would you recommend ?

Daniel @DeussenEngines is who I went with. The tune and service before and after the sale is great. He's out of Germany but has a US based distributor, RTB Motors.

Buying an amazing bike then chucking a whatever exhaust on it just so you can have something louder is fundamentally disrespectful to the bike... Akra is made by engineers from Ducati and Akra for the bike and comes with a great tune. That SC project slip on looks terrible, looks thrown on the bike. Here is the exhaust hierarchy for these amazing bikes:
1-Akrapovic
2-Termi (wouldn't recomend)
3-Everything else Bolt on junk including the SC project WSBK exhaust that cost $7k

Brentune is a laughing stock of bike tuning world, they are clowns trying to make a buck and they don't know .... about bikes.

You void your engine warranty also.

Makes total sense .

This is why I was hung up on going for the full underbelly Akra. I am very I decisive but It may be what I go for.

You say the tune supplied by Akra is great however if I do decide to go full akra system is there any other tune that is better? Something providing a bit more tweaking within the system in regards to performance is what I am specifically looking for.

(By cylinder tuning , quickshifter tuning , rev limit removal by gear, ect…)

Or would / can a full custom dyno tune along side the akra supplied tune be the way to go?

Well that Akra system you are looking at is for '21 MY bike and below. You can only tune per cylinder off the rack with he new Akra under tail exhaust.
You can add bungs to the older system you posted and tune per cylinder, if you are in NYC you would have to go north to HVMC to talk to Steve Saucier. Or he could do what your last point says - full tune on previous Akra on 2 cylinders and still have a great result

He's in the US. The warranty isn't immediately void because of a tune.

Touch your ecu with a non ducati approved tune you nullify your warranty.

I’ll touch my ECU however I want to. Not only I say so, but so does the US government. There’s a law specifically against such things here.

Besides, Ducati techs here seem to cause more problems than they solve.

You should try touching your ecu… you might like it

Question for the termi vs the Akra full … what did the dyno numbers look like compared? Mid range gains ? Top end gains? How much louder was Akra over termi slips? If rating them 1-10 on sound quality which score? Thanks for your help

I never put either on a dyno, and don't really put much in dyno results. There's too many variables.

I think the tune does more than the exhaust as for uncorking these bikes which are limited for noise and emission compliance.

Granted, removing the catalytic converters helps, and being lighter is always beneficial. I don't think the Akra was louder, if it was it was slightly so, but it had a different tone. More aggressive and race bike like. I don't like riding the Akra without ear plugs if the baffles are out, which they always are. I'd put the sound quality within a point, and that even being dependent on what you prefer. If I can throw a bone to the Akra system, being a full system, it get's rid of the clunky looking plastic heat shield under the seat in favor of a more sleek carbon fiber shield with a slimmer header shape. The Akra at full beans down a straight does sound amazing. For what I use my bike for, weekend rides and track days, it suits me better.

I bought the Termi slip-on as it presented the best value. At the time it was a tick over $2K with a Sprint filter and a tune. I randomly found a full Akra system on eBay listed by a east coast dealer which was new in box for $3.5k. I jumped on it immediately and sold the slip-on. Eventually I went with a tune from @DeussenEngines and couldn't be happier.

There is a factory Akra tune, but check with what ever dealerships are close to you. Mine wanted the bike to be trailered in with the turn signal fuse removed, headlights and taillights taped, ie things to make it looks like a track bike before they'd flash the Akra map. All of this and the dealership you bought the exhaust from has to register it to your VIN. I made a couple of soft attempts to contact the dealership I bought my Akra full system from to get this done, but I suspect I likely bought it when someone f'd up and listed a full system at the slip-on price, they haven't communicated back.

Sweet thanks for this input, does deussen engines provide a flash tune to run to the bike pending which parts I have installed? how does it work doing business with them? For example they provide the tuner device and tune?
