QD for Turismo too loud and questions

I've recently fitted a QD exhaust to my Turismo for two reasons;

One is that it looks, to my eyes, absolutely stunning.
Two is that it is throatier than the standard exhaust that is just too quiet.

Unfortunately, I'm a bit disappointed with it because the bike doesn't run well and is hesitant on the pickup, suggesting that a remap is required even though there is no mention of it with the system, as supplied.
Also, and I can imagine some shaking of heads here, I find it too loud, even with the baffles in. I've not even bothered to take the out the baffles to hear it.

Has anyone else had this "problem" and if so, have they tried to quieten it down a bit? If so, how? If not, any educated suggestions?

I had the same problem... the QD was a bit to loud for me (with baffles)
so I decided to change it to the HP Hydro tre
the look is awesome and the sound is just right

but the bike was running as normal always no matter what exhaust.

To be honest, I thing with the Hydro Tre the bike is a bit more torquey

There is no need to remap the ECU !!

So, the bike's engine characteristics changed after installation of the QD exhaust...and you believe there is no need to check what that change was by checking the tune on a dyno with a qualified technician.

I wish my ass-dyno was that talented.

Have you tried letting bike run adaptations?

Run bike at idle until the fan turns on. Let it run like that for a few minutes. The ECU may be able to adjust slightly to accommodate for the freer exhaust.

I find my bike runs a bit differently when the weather changes. But, after warming up fully will then adapt to changes in fuel/air mixture caused by temp differences and changes in oxygen content.

Worth a try but may need a tune to really be right.

That's a good point AirJawed and thanks for that as I've only just found out that the bike can do this.
I'm in the UK and I've since spoken to a very highly respected MV dealer in the UK, MV Agusta Dorset, who have told me the same. They said though, that in their experience of the QD systems being fitted to Turismo's, unless fitted from new, the change is too great for the adaptions to work. What they do is reset the ECU and the adaptions will then usually successfully "adapt" to the new system.

Progress on the sound front too. The same dealer said that they've had a few Turismo riders with the same noise concerns with the QD. What they have done is to wrap the removable baffle tubes with exhaust wadding and secure it with tie wraps, saying that it has worked successfully for their customers.
In the meantime, I'm going over to Custom Chrome in Nuneaton, Warwickshire soon after a very encouraging conversation. They are makers of the famous (in the UK at least) 'Cherry Bomb' silencers and specialise in bespoke exhaust and silencer systems (UK custom builders, note!). They feel that, although the wadding wrap would work, they can come up with a different, more effective solution so I'll update this post after the visit.

Thanks to everyone for their input.

I presume that's Motocorsa. When fitting my HP Corse Hydro Tre they said exactly the same thing; would need to come in for an ECU reset.

I think you can remove a main fuse and accomplish the same thing. Not sure on the TV but on mine there are some fuses on the right side above the common fuses. I think in the manual its the one to remove for long term storage. I mention this because it is far easier than removing the battery terminals. Removing power does not clear codes but does clear adaptations. So after doing that run the bike till hot(fan kicks in) and it'll adapt as much as it can.

My FM projects exhaust was F**K off loud so I bought some exhaust wire wool type wadding and shoved it in the collector box and it certainly took the edge off of the noise, although it is still loud . Done 5k miles with it like that and bike runs fine . Might put some fresh in as on the last ride it seemed loud .

I've been down to Custom Chrome (Cherry Bomb manufacturer) today in Nuneaton. What a place! Some mouth watering stuff on display for cars and bikes. Only took the removable baffles with me but the owner said that the inserts are a really bad design as all they will do is restrict the flow and cause the system to "ping" giving out a harsh noise (so true). He's proposed a solution of custom removable baffle tubes that he says should quieten it down and give it a much nicer, deeper note. I have to take the entire system back to him for him to work with so that will happen in a few weeks time. I'll report back if anyone's interested. In the meantime I'll be checking out Airjawed's suggestion of looking out the fuse. Bet it's there somewhere!

Good information and nice to know there is someone who can "fix" the problem
