I hope this post doesn't come-up "Lame".
I picked up my Modified F4 from the Dyno today, and wanted to post the results...............e-mail PDF didn't come threw yet so all I have to post is a Photo of the Print-out, (sorry). I hope it's legible......
172.82 Max Hp
79.48 Max Torque.

It looks to me like the Remus Muffler I grafted-on works pretty well.:f4:
Plus it's 16.5 lbs lighter than the stock pipe and mufflers with Cat.:jsm:

Great result.

Mine is much lower, 154 hp with RG4 and MWR air filter. Ducati 848 evo under same dyno result 117-118 hp.

I heard result will be different from one dyno to another though.

What modification do you do beside Remus muffler? ( I thought Remus just made for Brutale model).

Hi Jakarta, yes your right, can't really compare the numbers from different Dyno's.
I believe that my numbers are 11.5 HP and 10.5 Ft Lbs torque over a stock Y10 F4 on this same Dyno. But that wasn't my stock Dyno run.
My F4 has:
BMC Air Filter
MV Race ECU
MV INOX Exhaust (no Cat)
Power Commander V
Remus Hyper Cone (S1000RR Model)
Custom Link-Pipe and Custom Brackets (I made those)

My main concern was to remove excess weight from the Bike (at the sacrifice of the Traditional MV-under seat, 4 pipe exhaust, which I do like the looks of) and to eliminate the under-tail exhaust because of the Heat issues on the Rider, and the Heat to the Rear Shock Reservoir, but I was worried what the Stubbie Exhaust might do to the Power.

I think I'm a bit surprised it came-out this well on the Dyno.

I haven't ridden It yet, later today when I get Back from Work.

It's Still a really Lame post with my photo of the Graph, but i was really excited to post the result, and excited to get my bike back, as we had some "issues" at the shop with my Fuel Pump fittings.

I think that the Dip in the HP at the top of the rev-range might be the Variable intakes "sticking", or not working smoothly, as it was inconsistent, and the only thing my Dyno-Guy couldn't seem to correct on the Power Curve.
I learned of that Issue from reading an X-Bike's Post.

Good work Mark.
Thanks Donsy, hey that Torque-curve looks pretty-damn strong to me, but I couldn't find any to compare it to.

Have you seen any that are as flat as that one, or better, on an inline 4?
I really don't know if it's that unusual or not.

Although the four undertail exhaust tips are "classic", what you have done not only looks hot, it lightens the rear of the F4 visually. It must also bring the CG forwards which is also a good thing.

Thanks Dave, I know that a lot of MV People love the look of the "classic" 4-pipe undertail exhaust, but, I really don't give a spit. I like the look too, but it's just not all that practical.
Another thing my mod does is "highlight" the Rear Shock and Linkage, Visually, which will look great once I install an Ohlins and probably anodize the linkage and ride-height adjuster. (titanium finish)
I plan on installing an anodized alloy rear brake reservoir too, since you can see it so well now, and it also doesn't get baked anymore.
Thanks for your positive comments.:)

Hi bigfeesh, yes it sounds good, real throaty down low, and then it sounds very angry at higher RPM's.
Quite a bit louder than stock muff's, but not too bad.
I failed at adding a video clip this morning, booted off the PC.
Sorry. I'll try again later. I've got a plane to catch.........
