Hello everyone-

First of all please accept my apologies for posting this. I'm sure this horse has been ridden enough times already. I tried searching through the forum and I did find a great deal of information, unfortunately much of it only added to my confusion. 

As stated in the subject I have a 2006 Monster S4R. I would like to buy a full Arrow exhaust system. I am planning to have my local shop do the install and Dyno tune. They said I would also need to get a Power Commander. When I look for the Power Commanders I see two models. One is "street legal" (PCIII EX) and the other isn’t? (PCIII) What is the difference? I assume that this device takes the place of a new ECU? I also noticed on their website (www.powercommander.com) that they do not seem to have my model and year listed in their search… is that going to be an issue?

I was planning to also get a K&N air filter when I ordered these other parts... does this just go in the stock air box? Should I consider one of these open air boxes I've read about or does it really make that much difference?

I really appreciate any advice you can offer. I just want to make sure I get the right parts and that I get all of the parts I need at one time. If any of you can recommend an online vendor for these parts I would certainly appreciate that as well.

Thank you for your time and knowledge!

Get the PCIII. The S4 and S4R are the same unit, you can sometimes find someone thinking they only work for the S4, so it'll be discounted. Ebay for 240-ish. Sometimes you'll find a deal for $200.

Yup, K&N replaces the stocker. When you get it dynoed, they will cut the top of the box, to help it breathe better. The dyno tuning and the PC III will guarantee perfect fuel mixure.

There's a shop in Vegas thats got some great deals on Arrows www.gearitalia.com

Where you located? Elevation wise...

Thanks for the quick response!

I am located in Miami... just barely above sea level.

I'd send ya my map, but it's not gonna help ya... 5280 feet higher than you

Ha-ha... yea only a slight difference in elevation there!

I assume that when they tune the bike they will "create" a custom map for it?

Correct. You will have a map done for your bike, with your setup. I try to avoid days with extreme temps. Pick a day thats typical to your riding environment.  Usually a couple hours on the dyno, so expect a bill from $2-300 maybe??

Funny, just saw your avatar. That bike looks familiar 

Avoid extreme temps? I live in Miami man.. it's always hot!

Yea they told me that the entire installation and dyno would take about 5 hours... not going to be cheap, but I really want the exhaust and I want it done right.

If you're mechanically inclined, you can install the PC III yourself, saves about an hour. Lift the tank, just plugs in and wires to the battery. It will come with a zero map, thus it won't affect your current setup.

Here's what you can expect before and after. As have the exact setup.



Granted your numbers might be a lil higher at sea-level.

Also, some dynos read higher or lower than others, so take your final numbers with a grain of salt...

Yea I was actually thinking about that. I saw a website earlier with fairly detailed instructions on how to do it... it seemed pretty simple. (http://www.ducatisuite.com/powercommander.html)

That's $99 saved if it would take them an hour.

Find out how they're going to modify your airbox. Some places will just cut some holes in the top, others will cut the whole top off. Decide for yourself how you want it before dynoing.

Thanks Wanwo... any recommendations?

Well, I run with NO lid (just have some zip ties keeping the K&N filter in place) but maybe that's not for everyone. I'm generally a good weather rider and I don't use my bike for commute. A cut lid, basically the whole top cut off, just leaving the sides, is what most people do and how Ducati have their aftermarket airbox lids. Drilling the holes, usually about an inch in diameter in the top is, I think, if you're <really> worried about water getting inside, but from what people have said on these boards the fully cut lid is no problem even in the wettest conditions.

Well I broke down and ordered the new Arrow exhaust this morning.... and they are backordered!! 

I ordered the PC3 from another retailer... they also sell the exhaust but for $140 more. We'll see how long it takes this other place to get them in and shipped I guess.

Oh well... what can you do

Thanks for all of your advice and experience!

why not ask 'em to match the others' price, nothing to lose there
