addressing SOMEBODY'S exhaust concerns...

Full Yoshimura 4-2-1 system with PC3r  





Wait, this isn't Dan's rice-burner thread....

hahaha.

Interestingly, on those 4-bangers, the equal length header is a much bigger deal than on a twin, especially a 2v twin...

I don't think the Akras sound better. They have a great shape for the streetfighter, but I don't think they sound very good at all. I'd rather have Competition Werks, looks better again and has a good sound.

But if you are spending the money on full system stuff, you are off your rocker if you think its "far too much money" for the DP kits for what you get, when you end up paying nearly the same $ to piece together a similar package.

I'll be camping at CalsCrazy home engineering my next exhaust instead.  Just checked the rocker and still rocks just fine too.

i had a PC3 on my s2r and had a horrible experience start to finish with that thing

i've thought about buying a DP ecu for the S4R and just having AMS tune it...  http://www.gothamcycles.com/servlet/the-4034/DUCATI-MONSTER-S4R-VIRGIN/Detail

I hear they don't like PC's.  Or at least was told that about a year ago but think it was Scott.  Something to do with voltage but someone else chime in.

[fastwin]

You're right. Jeff hates them and I have no idea why. Starting with Scott and those before him (Brian Sharp, etc.) have all said Jeff doesn't like them but no one has ever said why. Weird. Must be personal. I have them on three of my Jap SBKs and a PC5 waiting to be installed and mapped for the Busa. All have worked perfectly. Maybe it's a language barrier, PC doesn't speak Italian or Kiwi!!

[muskrat]

I thought it had something to do with the Magelli system which is one reason they've moved to Siemens.  Again, someone chime in otherwise a rumor will begin to develop.

AMS most certainly does not like PCIII, and i'm totally fine with that; i can see why they wouldn't.  i had it on an s2r, and it was just a mess... the first shop i took it to couldn't set up the maps for shit and the bike ran horrible...  the second place set it up nicely (jim sabin), but then the unit was defective or something and was losing maps or didn't want to accept new maps for individual cylinders or something; he was having a tough time with it. 

[junior varsity]

They do't like them because there is a big voltage difference in what the bike is doing there and what the PC3/5 wants. its a goofy setup at the best --> if you are going to go aftermarket, nut up and go Nemesis or MicroTec.

So if a person, was to say, get a Zard system - $1,750, and a Nemesis or Microtec - $1000, you are barking up the tree of the same cost as a DP kit.

Shop in Nashville had troubles getting PC's to work as advertised too - they could get "something" doin', but all parties ended up dissatisfied. Much like after a night with muskrat.













Bazinga!

Buying a DP ECU (or an ECU flashed with the DP maps - slip on or full) is pretty reasonable now.  ECU's are around $4-500 (cheaper if you are patient and search), reflashing yours is around $300 (Ducati Depot, desmo porsche).  While not as finely tune, they are good, safe maps, that get rid of the smog constrained factory tuning (disabling O2 sensors, flapper valves etc) and give a nice power bump.   Unless you are racing, or racing dyno #s, they should get you what you need to enjoy the bike and your pipes of choice. 

There are shops now that can also custom map the Duc ECU, but as with all custom mapping (PC, nemesis etc) your results are only as good as the tuner working the keyboard.  The Magneti Marelli system is not a bad one, it just cannot meet the fine closed loop individual cylinder control needed for the tighter 09+ emission regs.  For performance, it is fine.

Josh, don't cash that Termi commission check until I endorse it

so, if i reflashed my stock ECU, would AMS still tune it?  i would tend to think not...  so at that point are you just basically reflashing it and having it sent back with a "pretty good" map based on what pipes/air box setup you have?  if that's the case, it might be worth it to just get the DP ecu from a place like this:  http://www.gothamcycles.com/servlet/the-4034/DUCATI-MONSTER-S4R-VIRGIN/Detail  and i would think AMS would be okay with tuning it.  i may still check into the reflash though; if it even gets me most of the way there i would be happy with that i suppose.  what does dyno tuning even cost now at AMS?

Rich,

Gotham Cycles treated me real well in my one and only dealing with them. I bought a set of Marchesini 5 spoke take offs for my 916 from them off of ebay motors a couple of years ago. They even drop shipped them to AMS/D for me since the bike was there for work. The wheels were in perfect shape! Amazingly I was there when UPS dropped them off and Jeff and I unpacked them. They got the coveted Jeff Nash thumbs up!! They also stayed in touch via email the whole way through. I'd use them again in a heart beat!

MY OPINION: about all slip-ons are gonna do is make the bike exhaust louder, more "manly".  HP?  Accidental and nominal.
Reality check: If you could have your bike supercharged for a 40% increase in power at half the cost of the pipes, but the exhausts had to remain vewy, vewy quiet... would you do it?

MY OPINION: the current crop of exhaust pipes are butt-ugly tin cans... look like somebody's 8th grade science project.

MY AMBITION: to find someone who will make a quality pipe for my ST3 in a long, slender megaphone with the reverse meg end cap... like the old Dunstall pipes.  Not carbon, not chrome. There's a manufacturer not far from Moto Liberty that I'd like to talk with about such a project.  I have the DP ECU, so lack of O2 sensor and adjustability s/b OK.

I'm guessing, but having some custom-made pipes right here in Dallas can't be much more expensive that them I-talian tin cans, especially figuring in freight and dealer profit.

I use Gotham Cycles too! Great outfit!
