I have a QD fitted to my Multi, I took the baffle out when I fitted it. It really isn't much lighter than the original can. Also really if I knew now , I probably would not of purchased it , as most of the muffling is in the exhaust/cat box underneath.

Thanks for your reply GCT, It leads to pretty much what I thought I had read amongst the multitude of googling different posts etc... The Cat does most of the baffling, hence my curiosity of what just going decat only will sound like ???

And thanks DaveAU for the very valuable info on the pipe sizes which indicate std can's may not work 60mm vs 50mm. I too found the same dyno tests showing all combo's of decat and both QD and std can's ... something is not adding up with fitment here, I checked the add I found again and it definitely states "all silencers that mount on the original cat" that is both factory Std and Akra slip on's - the add I found and Bellissimo use the same part number ADUC0600005. Looking closely at the pic the outlet pipe does appear the final slip joint piece does step down in size so maybe it does work together ??

 

[DaveAu]

Well spotted Shizz..... It does look like the 60mm exit pipe steps down to the stock Ducati size......

That's a relief, and it makes sense, otherwise all the QD mufflers wouldn't fit.

So I could still make some music using my Akra slip-on ...... .

Today has been all good news...for a change!

 

[mixedup]

Not sure if any of you are considering the Akra 3/4 system….but we just had a significant price increase on it in Canada (went from $3680 to $3975!!!!).

 

[DaveAu]

G'day all, any news is good news, right?....... well here's some info anyway, good or bad

Aus dealership/Ducati Akra full system pricing also jumped up from around $4.5k to almost $5k this year, but there is no stock in the country as advised by my local sales manager who also said the exhaust was 'made to order' and she frowned when she could not confirm a delivery date, saying instead, could be 6 months......little did I realize how right she was until I got a reply from the seller I ordered from (in Italy) stating production was delayed (even though they advertised it as in stock ready for immediate posting) until after 15 June 2022 due to the war in Ukraine......... so no one will have stock unless they had ordered a shipment and had delivery before the war broke out.

Also, ....having become interested in the QD decat pipe thanks to ShizN' Giggz,..... I stumbled onto an Ebay seller in Italy advertising 2 in stock for just under $1300Au - BUT they don't send to Australia - however they confirm the outlet tube accepts all standard slippons........ see attached screen dump.......

PS The Bellissimoto Las Vegas and QD EU sites have been the only ones that mentionthe QD piggy back tuner module quoting around $650US..... others mention retuning but I don't know if they mean plug in or a Rexxer dyno re-tune or ???

I'm not talking the stumpy little Gunshot muffler, rather the QD Decat mid pipe, which replaces the original collector box - both the standard exhaust (muffler) and the Akra slip-on Ducati official accessory are straight through with no restriction (not even a dB narrowing tube) as all the Euro 5 work is contained within the collector box under the rear swingarm and gearbox.

The plan is (because I already have the $2k Au Akra slip-on muffler) to decat and continue to use the Akra slip-on......so far all my internet searches have found is that the QD decat mid pipe assembly is about 800 euro and the QD tuning modue is about 500 euro..... no freight figures to Aus because the local agent probably has an agreement to protect local sales even though he likely does not carry stock and just orders as required........ but I'm still not that interested in paying over 1700 euro just for a decat without any word on how it affects the performance (I know, it yields approx +16Hp, but does it kill the marginal fuel range of the V4 in the process, or does it actually improve it when not playing hard to catch?). Naturally I would like some more music, but not so much that the plod will be attracted and want to talk to me whenever I ride past.......

I got my QD from Torque power in QLD, but it was a bit cheaper than they are now

Cheers GCT,

Are you talking about the QD Gunshot stumpy muffler or the QD Decat mid pipe/collector assembly and tuning module?

When I talked to Torque Power last year he seemed totally disorganised and I gave up trying to buy the Gunshot muffler I thought I had to have and bought the Akra slip=on ex stock at my local Ducati shop. The mufflers (stock, Akra and QD) all have no baffle plates or restrictions as the collector under the engine and swing arm does all the damage to music and gas flow.

I found another site that published specs for the Decat assembly and it confirms that the decat collector works with standard headers and all mufflers that fit onto a standard V4MS will also fit the Decat collector mid pipe.

Now to find a bargain price with good delivery terms.....be that my disorganized friend at Beenleigh or someone in Italy or the UK that will post to Aus........without any delays caused by the bloody war in Ukraine

....one of these critters..... see below.....should make some music but at what cost?

 

[GCT]

Dave AU, just the muffler as they didn't make the mid box when I purchased it

 

[DaveAu]

GCT,.....I think I'll have to ride over to Torque Power during the week (assuming he will be open and not sleeping off his overnight internet conversations with Italy), and see what he is up to. If he has one on the shelf I'll be in trouble.....

 

[GCT]

ha,ha

 

[DaveAu]

ha,ha

Yep, I'm now toooo...... Torque power m/c is listed on google as 'temporarily closed' at it's Windaroo address (no explanation), so I stumbled onto another reference for TPM at 142 Beatty Rd Archerfield address ...... Maybe he's moved from his hard to find little shop? Or maybe someone has bought him out (spotted a business for sale note somewhere)......but it's a public holiday today so the mystery continues and my money is burning a hole in my pocket .

It's all sounds a bit dodgy so I'm rapidly losing interest in spending $2.5k Au on a decat pipe and Rexxer or QD tuner module.......... .....I think I should leave my dosh in the bank and just ride my well running V4MS in stock tune with my fancy Akra slip-on muffler....... even the US and EU QD seller sites are proving difficult to get a price & delivery quote to AUS.........

Must be the new way to do business......make the punter do hours of work for no result.......

At least I know there is an option to the Akra decat that I can use with my Akra slip-on and an upmap that I can install myself....... maybe one day all these 'agents' will sort their out and do something to attract a sale.

 

[GCT]

Sounds like a great plan. Use the money saved for something else.

And here is the latest in the saga.......... after running hot and cold on the idea, the Ebay seller updated their delivery list to include AUS (fancy that??)...... then they knocked $50bucks off (to reel me in),...... I had no chance!........ eventually I reasoned that as I had previously chosen to buy the full Akra (accepting that the war in Ukraine caused that to fall through), then this option - the QD Decat mid pipe - was better in that I already have the Akra slip-on, so I wouldn't end up with two spare mufflers.......

The issue with the local agent forced me offshore (luckily) and I found two sellers in Italy, one on Ebay. They had far better pricing than the Aus agent, though freight was $208Au, but in the end the Ebay seller had the best price plus the proven Ebay money back guarantee, so 'dBKiller' won the deal....... I paid $1450Au delivered, and should see my QD Decat by June 7th........

I studied the dyno charts again and it appears that the expensive little QD ECU map module isn't necessary however if I later feel that I want the slightly better mapping below 3k rpm and above 10k rpm then I can pursue either the QD or a Rexxer map module later, but it sure looks like the stock ECU can adapt to the decat design without mods.....

Happy days... (I hope)......

 

[ShizN'Giggz]

So after much postulating and tossing up all the different options I have finally done the Same as DaveAu and chose to hold off on the remap, Geez having 170 ponies on tap is mad enough and don't use them all let alone whackin her to 186+

Found multiple sellers in Europe including going direct to QD, prices including shipping to AU were pretty consistent ranged $1300 - $1400 AUD catch was in the "in stock" and shipping, found OS seller using DHL were usually 5-10 days which is pretty bloody good for us here Downunder.

Here's hoping I'll be fitted up and making music by months end 😁

My bike is scheduled for first service and install of the Akra 3/4 system next week. I’ll report back. I cannot WAIT!!!!

I had the dealer in Las Vegas Nevada install the full system on my 2021. The improved performance was noticeable and the surging was gone. On the downside I found it a bit too loud for my tastes so I have reinstalled the cat and had a "Y" pipe made to connect the cat's single outlet to the Akra's dual inlet. The Akra can was just too pretty to sell. I've put a 1000 miles on it since and all the benefits of the ECO mapping are still there. My buddy has the full system on his as well (we did it at the same time) and a roll-on finds that he pulls me for the first 100 feet or so and then we are dead even up to a "very high" speed. Fuel consumption is running the same as it was pre-cat which is tenths of a mpg less than the stock mileage was. So, I ended up with the ECO mapping, a pretty can and a relatively stock sounding system. I'm happy

Hi Marc,

Looks like you’ve got a great compromise there. No surging, more power and not noisy.

Did the pipe and chip completely and permanently (so far) cure the surging/stutter issue? That why I would do it.

thanks,

Blair

When the system was initially installed it eliminated it 100%. As the adaptations accumulated it picked up an itty bitty amount, almost imperceptible (and maybe just in my mind) except to OCD types like yours truly There was no change since reinstalling the cat so I think whatever adaption was made is now set in stone so to speak. A simple answer to your question is a resounding YES, it fixes it and thank goodness for that! I hated it Always reminded me of the older BMW R1100 bikes that used to make me crazy.

Marc

 

[marcparnes]

The one downside to this expensive upgrade that someone might want to consider is that the ECO mapping that comes as part of the package and the main attraction in my view, is not contained in any physical form, rather it is downloaded from Ducati by the dealer and tied to your VIN. The obvious downside is you can't take it with you. No moving it to a new bike or including it if you decide to sell the exhaust in the future. Just a heads-up if you're someone who likes to change bikes in the short term. I rarely keep bikes more than a year or two but getting rid of the surging was still worth the price of admission to me.

Marc

 

[mixedup]

Definitely an expensive solution as you can’t sell the 3/4 system to recoup costs. If anyone is looking for the slip on only (no modifications necessary!), will be selling mine next week!

Off to the dealer to pick up some stuff I ordered and I’ll see what an installed cost would be on a full exhaust. Maybe they’ll take pity on an old retired guy. Ha!

This is I think my 4th last bike in the previous 7 years. If I can get rid of the stuttering/surging, I don’t mind the idea of keeping the MS V4s a long time. The bike is otherwise fantastic.
