Exhaust volume
Hey guys
I'm trying to decide on the 14 exhaust. My ZX12R has stock headers and a Muzzy oval bolt-on can. It sounds fantastic but it's a bit on the loud side - surprisingly so considering I've still got the stock headers.
I love a little meat to the exhaust note but I don't want to sound like a full-on race bike as I ride up the street. If anyone has a recommendation as to an exhaust that has given great results on the 14, but isn't stupidly loud, I'd be interested to hear.
I've spent ages on youtube etc looking at vids of bikes with different exhausts but it's really hard to gauge the sound level recorded through crappy microphones and regurgitated by crappy computer speakers - a lot of them are distorting as well.
Looks-wise I'd go with the Tsukigi - at first I thought "what an ugly piece of sh.." and over time it's grown on me and I now really love the look of it so that's high on my list although it doesn't look like it has much 'muffler' to it!

check out the brocks gen3, or smeg. i have the shorty gen3 and it's not loud unless you want it to be. the full length 20'' can is quieter than mine and you couldn't ask for better customer support. the tsukigi cannon is reterded loud and according to greg at hpc makes less hp than their standard oval. build is supposed to be very good on the tsukigis, but they are not quite as powerful as a muzzys or brocks. I say brocks all the way!

if you can get some decible specs on various pipes that should tell you the story. Just don't be fooled into thinking a pipe that is a couple decibles more is only a little louder than the the one that is a couple decibles less. I think I've read that every number on the decible scale represents a volume increase of 2X or something like that. I'll see if I can dig that article up and post it on a sepparate topic.

High frequency sounds of 2-4,000 Hz are the most damaging. The uppermost octave of the piccolo is 2,048-4,096 Hz.
Aging causes gradual hearing loss, mostly in the high frequencies.
Speech reception is not seriously impaired until there is about 30 dB loss; by that time severe damage may have occurred.
Hypertension and various psychological difficulties can be related to noise exposure.
The incidence of hearing loss in classical musicians has been estimated at 4-43%, in rock musicians 13-30%.
Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin , M.Sc., Aud(C), FAAA, Centre for Human Performance & Health, Ontario, Canada. There were some conflicting readings and, in many cases, authors did not specify at what distance the readings were taken or what the musician was actually playing. In general, when there were several readings, the higher one was chosen.

Rook,
try to guess which part of the 13-30% window of hearing loss I am at. LOL
Just consider I started taking drumming lessons before any other kind of lessons...
no wonder I don't need earplugs for riding.
IMHO Loud pipes save lives!
And you can also remove the horn from your bike like I did!

i am an asw acoustic operator so sound is my job. a 3db increase doubles the volume or intensity of sound.

Same here- sound is my job!
I'm actually very careful and always ride with an earplug in my right ear.
Left one is just more alert for the noises that cagers would make when
about to take you out

I like the gen3 sound, much more civilized until you get on it.
I sold my Gen3 before I tried the Smeg or I would not have done it.

The tsukigi makes a very nice sound, maybe too loud for what you want. A friend has the full titanium system on his Busa.

^^^Love that 'zaust. Looks like it was made for a busa but it is very nice on a 14, also. You want to know what it looks freakin excellent on is the ZX-10 which already has the GP style upsweep that that pipe was modeled after. Get a load of the hole in that thing! That looks LOUD!!!
I think Alien Head looks best of the full systems on the 14 and it's loud and I think the boost will be most significant. Great support, too. Brock's sure seems to be a crowd pleaser.

I have a Tsukigi full stainless Oval system. It is loud. Fantastic welds and material. Love the look. Choose it for all the crappy weather and road debris here (Heavier gauge pipe too0.
If I didnt ride all winter and also find a pristine used system for 1/2 price, I would have gone with a Gen 3 and Brocks great service.
