Question guys.. I'm getting a full arrow pro racing exhaust for my 2011 brutale 1090r.. it says u don't need to tune or map as it will work with the stock ecu... I always thought u gotta remap/Tune when putting a full exhaust.. This coming from arrows websites any suggestions. .

I got the same bike with the Tamburini (by Arrow) exhaust. It should work fine as long as it's in tune. If you do any other mods beyond that, including an air filter, no guarantees. I had Ferracci install mine, he dynoed and made a few adjustments. I got the impression that if he didn't dyno tune it, the bike still would've been ok.

See this from arrow.... MV Agusta Brutale 1090 RR / 990R Exhaust by Arrow(MVA71161RKI)



MV Agusta Brutale 1090 RR / 990R Pro Racing / Thunder Full Exhaust System by Arrow

These very well constructed approximately 8 lb units replace the stock headers and mid pipe/catalytic converter(boat anchor) on your MV Agusta Brutale 1090 / 990R exhaust system. Significant weight savings and an approximate increase of 4 -6 hp with better all round torque and throttle response. Your Brutale will respond better, run cooler plus you get more HP to boot. According to the manufacturer, this system utilizes the stock O2 sensors and will run just fine with the stock closed loop Euro 3 ECU. This unit is slightly louder with the dbKillers out than the previous Thunder exhaust for the older Brutales. DBkiller included.

These Arrow exhaust are easy to install. Comes with everything you need, including springs.*

Arrow headers/collectors (71428MI) are included to give your Brutale a Full Exhaust System, and give you maximum horsepower and weight reduction.

Fits:*Mv Agusta Brutale 1090 RR / 990 R/920/750/910

Hi Sic, I just put the same system on my 2011 Brutale, ran ok but didn't feel as crisp as stock but had very loud backfiring on thr over run. It's getting PCV fitted & dynotune done now. I'll update when I get it back.

From my experience , about half those claims from Arrow seem true. Yes, it's much lighter. Yes, it's much louder with the db killer in . With the db killer out, earplugs aren't a bad idea. As far as the increased HP, torque and throttle response goes... I really didn't notice any discernible difference, in my case anyway. It very well could have picked up a couple horse and torque on the dyno sheet, but we didn't dyno my bike before the installation to get a baseline. Since I'm not competively racing, and I'm not trying to shave tenths of seconds,all I care about is how the bike actually feels. I don't really feel the engine itself has a lower running temp due to the exhaust change. I'm not really sure why anyone would want a lower engine running temp anyway, unless your overheating . There's benefits of keeping your engine in the recommended operating temp range. However, there's definitely less heat thrown off the exhaust that is usually felt by the rider. I really can't speak about the ease of installation comment. I didn't install mine, but I could have. The ease of installation really depends on ones mechanical prowess and tools available to them. Some people have problems hanging a picture on the wall...

Got the full system with open silencers on my 1078 and she runs great, probably no different from stock apart from she seems quicker to rev out and runs a lot cooler. The low down surging is still present but theres no popping on decal, all in all very happy with the system although a microtec. or pc would probably improve power and get rid of the surging.

Hey, since it seems a few of us have the 2011 1090R, I was curious as to whether you've ever had your dealer do a software update on them. I've asked if there were any new software versions released for it every time I took it for service, but it's been a no every time.

Wondering if it was just my dealer not being proactive or if they haven't updated the system for these bikes at all.

Ah, okay, there's certainly a lot more of this starting to happen around the place. Good option to have for sure, even better if he knows MV.
Ya hope we get more dealers..having one means longer want time since we have shorter summers here

Sure get a video on that dyno mate

Running same exhaust set up and had same surging symptoms along with the on/off switch when applying throttle, even with race ECU and PCV. Symptoms gone after custom map made with dyno. My tuner downloaded the "accelerator pump" option to tune the on/off abruptness of the throttle.

Got the full system with open silencers on my 1078 and she runs great, probably no different from stock apart from she seems quicker to rev out and runs a lot cooler. The low down surging is still present but theres no popping on decal, all in all very happy with the system although a microtec. or pc would probably improve power and get rid of the surging.

Hi guys, Got my bike back, not very happy with the results. Under full accelerations it's great, noticeable power increase but at low revs it surges & occasionally stalls, pretty frustrating. I don't think they reset the TPS or adjusted the idle, bike's due for 24000km service in 1500 k's so I'll put up with it until then & see how she runs after. Pipe is VERY loud too, even with Db killer in. I'd look at the Arrow headers/stock muffler option.

I take it back, went for a ride this afternoon & she went like a rocket. I boosted the idle up to 1250ish rpm with the fast idle "choke" lever & its a lot better. Maybe the O2 optimizer which apparently looks after things below 6500 rpm takes a while to get it right?? Had a very slight momentary flat spot around 3500rpm but it seemed to disappear after a while. Seems a bit quieter now too, do mufflers take a while to bed in? Pretty happy with it so far, once TPS is reset, throttle bodies balanced & idle adjusted she should b sorted. : )

That's good to hear. I will be looking at putting the same system on my bike in the future. I may have missed it but you are running your stock ECU and not a race ECU, correct?

I hope it's OK to ask this in your thread and if not I will gladly start another, but has anyone received a Microtec map from X81 without physically having their bike put on a dyno with him? I would be talking about the non UK members (US, Australia). I tried shooting him a PM but his inbox is full.
