MV Mitch, I am in the same boat/bike. I am looking at "mufflers" plus I want to remove the cat with a mid pipe, so I will watch what you decide on with interest. George

Ideally I just want the bike a bit louder for when

I assume, you want twin pipe, for .........? Headers pipes, actuator valve (the resticted power) and catalytic converter (the ugly box) they may be weld in one pice ( i got 990 R 2010, than was weld in mine) not to mention they are super heavy ( i think around 22 lb.) compare to MIVV (2 lb.) 9" long (around $375-$400).I change handlebars also. But , is your choise. Merry Christmas Everyone.:violin:

Wow that's a clean looking bike, very nice.
I am not chasing a power increase, already has
plenty for me. I really like the look of the twin
pipe setup.
I will be doing a few long trips with the mrs on
the back so it would be nice if it was not to loud.

I have the std cans and a de-cat header, its loud enough, you can always take out the air box restrictors if you want some induction noise on top ...:)

Merry Christmas everyone!

Ok so I am looking at upstaging just the mufflers
On my 2012 1090r and have been looking at these

I am in traffic, probably getting to old for a full
Open Ti system.
If anyone have used either I would appreciate your advice.

Thanks
Both of these are "race" pipes, i.e. no db killer. I think they are intended to be used with a full system, including "race" ECU. But they look great...

I did contact evolutionbike about them before I ordered them
and was told the ones I picked are not completely open so I am hoping
they will be ok.

I really like the look of them, I will be ordering the rest of the system including the ecu when funds permit. Then I will be able to swap and change to get the combination that's suits.

Don't think they will be here till mid jan so I will have to wait and see.

Thanks for the input everyone.

Just curious...

Just like billywhizz I replaced the stock headers and the cat with this Arrow inox headers/mid pipe and kept the stock silencers along with the ECU and the Lambda sensor

http://www.evolutionbike.it/mvagustastore/index.php/exhausts/brutale2010/arrow/71450mi.html

It is a perfect setup for my taste - loud enough but not too loud. The bike seems to run cooler and smoother too.
Did you receive instructions of any sort with the headers/midpipe/ECU combo? I have this kit as well, and it looks rather easy to install but i've heard that air injection needs to be blocked off somehow and they include a rubber plug with the ECU that must be used for this purpose.

Thanks!

Arrow 71450MI

Hi jones525,

I received no instructions at all with this manifold. But I only got the headers and the mid pipe - Arrow part number 71450MI. I did not replace the stock ECU. I kept the Lambda (O2) sensor as well. Other forum members like Glenn (G21090) who gave me some advise, have done the same.

The manifold is really easy to install. The more difficult part is removing the stock headers as they are welded through into the cat - so it's one unit. You will need to unmount the oil cooler and get it out of the way but no need to disconnect it from the engine. Also, you'll need to disconnect and remove the cables off the exhaust valve as they are not needed with the Arrow or any other aftermarket mid pipe. Also the cat hangs on two rubber mounts with snap-on rings on the inside, which are a bit difficult to get to but you'll be fine.

I'm very happy with this setup. I've had no issues with it. It did drop about 7-8lbs & cut way down on the heat coming from under the bike. And it opened up the sound, keeping it pretty much the same, albeit it more intense without being obnoxious.

I think somebody had already posted pictures of the installation process. Let me find this post and I'll copy the link here.

Good Luck!

You didn't get an error code at all? In my recent service, the software re-calibrated the operation of the exhaust valve - it took it from closed to full open to closed again. If the motor is left on without cables, that process would not be possible.

Nope, no errors at all. I didn't disconnect the motor, just the cables to the exhaust valve. Need to do it since there's no exhaust valve in the Arrow or MV Corse (which are made by Arrow btw) mid pipes.

ok this is interesting,this is what we did on tony brutale bike 1090 new headers and mid pipe,left original cans,just tied the wires up under the bike ,but replaced the ecu with a race ecu and pc5 ,had it dyno tuned ,well just perfect,no snatchy throttle what so ever,full control from 1250 rpm to whatever. are you getting the same results, just curious.I also understand that the Microtec will give you similiar results.

Why did you put in a PCV on top? Isn't the race ECU enough?

I'm asking as I have the MV race kit (headers and ECU) lying in my garage. Will install it after the engine is broken in......

So what would be the better of the two to get? The mv corse headers and mid pipe with the ecu or the arrow one.

It kind of depends what you want. Arrow and MV Corse manifold/mid pipe are pretty much same. I think the MV Corse manifold is manufactured by Arrow anyway. The possible applications are with stock ECU and lambda sensor or with race ECU and no lambda sensor. Some people add Microtec or PCV on top of the race ECU to smooth out power delivery. Perhaps the race ECU alone is "snatchier" than the stock one. I guess the race ECU will increase power but IMHO the bike is powerful enough with stock ECU as well.

Hi Eddypro,

I have no issues with the Arrow mid pipe and the stock ECU. The throttle isn't snatchy...maybe just a tiny bit at very low rpm but not bad at all. The bike pulls hard from any rpm too.
