Muzzy full dual exhaust
« on: October 04, 2011, 05:48:54 pm »
I'm thinking of getting the Muzzy full dual system How many people have them? How do you like them? Are they a high pitch or low? Loud at cruising speed of say 65? Good power increase? Anyone have a sound
clip of them running? Cant find any on youtube. Thanks!

I used to wonder the same thing.

looked at some pics from ZG,called Muzzy .

Muzzy claim the exhaust is quieter than some aftermarket single cans. That may not be what some would think, but I think it is , as muzzy says it would. In order to do it with one can it has to be large, this has half the flow because it is 2 cans and twice the packing.
The sound is a little louder than stock but not loud in my opinion. It is an incredible cool sound though. I love it.
They offer a couple levels of "quiet core" and "whisper core" type baffles, but I would try it the way it is because it doesn't seem loud at all to me
and I do not find any "drone" when cruising that I heard may bother people with some pipes. I've only put a couple hundred miles on em...but have ridden different speeds,etc.

Mine is just installed with the powercommander muzzy sent with it (pre-programmed) , and it is a good gain over stock in hp...they claim 17% .
 The bottom end is much better even though I do not have the flies done like some talk of. above 5000 rpm the difference is very distinct. The new headers seem to be a stepped design and are much larger diameter than the stock ones. Muzzy claim this model was way de-tuned from factory , and that is why such big gains from the system.

All in all it was the only choice for myself....because i never liked the look of the bike in its stock " unfinished " form.....no pipe on the left side didn't work for me.
It even looks HOT when the bags are off !...how can you beat it?

everyone likes something different, but for me it has me so I want to drive it all the time, it sounds better, it looks better (about 1000%) .....only drawback I can see so far is that it seems to make me speed, and I dont want to lose my liscense...I never really had that problem before installing this exhaust.

If you think it suits you , it probably will...go for it.

...remember, if you can afford it, you should spend..you are only here for a short time...just think about how long you will be dead someday!

Yea, I ordered the Muzzy full system yesterday. I also talked to Curt and he told me the same thing about it not being super loud, but just a good mellow sound with lots
of performance gains. I'm going the re flash ecu route instead of PC3 or 5. Can't wait to get it on.

What would be totally sweet is if Guhl motors could get a hold of one and adjust the ECU maps.......

Well, I know that my Holeshot Performance slip-on is good for a few extra horses.  Bagger (who I bought the Holeshot from) put on the Muzzy's and gained 10+ horsepower over that.  I think muzzy's gains are in line with what the Area P full system claims for hp gains.  The Muzzy's do look good, too

Joe at Dynotronics already has all the info for re flashing the ecu for the Muzzy full system!

Does the Dynotronics flash preserve the Eco mode? I kind of lost touch with those discussions.

I didn't know about the dynotronics. Maybe in spring .

I hate that cold weather is closing in on us here in the far North East.

Nova Scotia is not at the end of the world...but you can see it from here!

Yes,
  The ECO mode is preserved with the Dynotronics ECU flash.  I've had my Muzzy Dual system on for over 15K miles and 1, it is not loud unless you are WFO and 2, there is no drone at all.  Itś a great sounding/looking system with definite gains over stock.  I do it again.

 Finally got my full muzzy system installed along with the Dynotronics re-flash. All I can say is I love it and it runs great! It has a deep low tone and no drone. Sounds awesome!

Yes, I went with the carbon fiber. It rained all day today. I will get some pics this week when the sun comes out. I promise  :)

How involved was the install?
You only need two tools in life – WD-40 and duct tape. If it doesn’t move and should, use the WD-40. If it shouldn’t move and does, use the duct tape.

Actually it was easy! Just remove stock and install new. I took all plastics off and just unbolted the radiator and used bungy straps to pull it toward the front forks to make room to tighten the header bolts. Excellent quality and everything went together great. Did I say how great it sounds?  :))

Man I hope I can afford this come spring,  I LOVE the look of it :)

PS, did U do a Power commander or ECU re-flash? or just the Exhaust?

I like the looks as well.  I may do this in the spring as well on my 2010.

Same on the ZX14, basically. Makes sense.

Did any of you with the dual muzzy change to a colder plug?

Are you talking about spark plugs Tim? If so, no I didn't.

I did not change to a colder plug with my Muzzy, why would you even consider that?

I heard the someone thought that Muzzy recommended it cause of how much extra air flow we have with the exhaust. I was going to call Muzzy and see what they had to say.

Tim,
  Here is a good reference on spark plug heat ranges: http://www.dansmc.com/sparkplugs1.htm

A spark plug does not make your engine run hotter or colder. The terms hot or cold refer to the temperature of the tip of the spark plug itself. The plug must keep a temperature of, between 752 and 1652 degrees Fahrenheit. If it gets too hot it can fire off the air/fuel mixture at the wrong time. This can cause detonation and/or pinging which will put a hole in your piston... not good. If it gets too cold it will not burn off the carbon and fuel deposits on it's tip and the plug will foul out (stop working) not good either.

The heat range of a spark plug is controlled by the length of the center electrode. A longer one is hotter because it takes longer for the heat to flow through it to the cylinder head. As you might think the cooler plug has a short center electrode.


  If your plugs are dark or carbon fouled, you may need a hotter plug, if they are whiteish or damaged at the tip, you may need a colder plug.  Pulling your plugs and reading them is the only way to get an accurate idea of how they are performing(see the above article).  Pre-ignition or 'pinging' can be a sign of a too lean a mixture also.  A colder plug 'can' help in this scenario but correcting the mixture is the better route.

Thanks Mick. I did call Muzzy and they said no way would they tell or suggest going to a colder plug.
