New Termignoni pipes way TOO LOUD with bafflers removed

[Mr.S2R]

Isn't that the way termi are meant to be? LOUD!  I think my Termis came with a warning - NOT INTENDED FOR ROAD USE, but meh, loud pipes save lives I say.  I would say that mine would probably just be over the legal decibel limit.  Friends say they hear my bike over any other from at least 1.5km away.  My cure?  I would put back on the ugly udder under the S2R.  Does yours have a cat you can stuff?

A big +1 from me, but as Matty suggests, my bike is on the border between loud and obnoxiously loud.

On the weekend , Matty and I did a very early mornining rnp run, and we stopped at bald hill and got into a short convo with an older fellow rider. As we went to leave, he noted us putting in ear plugs, and asked whether they were needed....

I just continued to put my helmet on, smiled at him, and said "why don't you makeup your own mind whether we need them".... Swung a leg over and fired her up. No further explanation was needed

Hi all,

I installed my new slipon Termi pipes & high flow air filter a couple weeks back and they sound awesome; a deep loud thunderous roar!

Unfortunately though, I have decided that they are just way TOO LOUD for me, my neighbourhood, random car alarms, little old ladies and baby kittens.  In fact, they are much louder than my old 620's CF Termi pipes, I don't know if it's due to the slightly bigger engine or the fact that they're full metal vs carbon fibre pipes.

Hey Rod

1, Now you know why most of us wear ear plugs

2, In your Hood don't rev the shit out out of it till your out of ear shot

3,Old ladies are deaf any way

4,Kittens will grow up

5, (Too loud for me) HTFU

6. (random car alarms) Random only

7 Or move from the Hood

I am, at times, partially fond of setting off the odd car alarm..

I wonder how many were set off by you guys whe you parked in the opera house car park to see the Tt movie.. Bigiain and I have  many times discussed the merit of this type of hooliganism on the fine arts!

hehe +1 on that!  I love rumbling along hearing the odd alarm go off, or pull up next to the Porsche/Mercedes/BMW with the window down, that suddenly goes up...

Well I had a bit of a shock when I went out to measure the decibel difference between my Termi's with and without the baffles. It seems that Fraser's never installed the baffles on my slip-ons and I've been riding without them for over a year now.  I never thought to check, I just assumed they were installed but on closer inspection the screw hole was empty and with the help of a torch I could see there was no baffle in the tube. No wonder I thought that with the baffles the bike was loud enough

So, I found the baffles in the box with the old cans and installed them for giggles and yep, much too quiet for me. After measuring the noise level I whipped them out again. I've attached a photo of them because mine don't look like the ones below, mine aren't plugged at all.

For what its worth, the noise reading, with and without baffles, is about a 25-30% difference. Quite a bit. I'm not sure how accurate my meter was but the decibel reading without baffles was about 104-107dB and 75-80dB with. Of course this was at idle and will be much louder under throttle. Do I care, not one jot.

I keep the noise low in my own street , after that its free for all 

earplugs i only wear for wind noise protection , if riding local below 100k then i dont bother
for day trips then earplugs are essential for the wind noise and they also reduce fatigue

car alarms brings a smile to the face 

tunnels , overpass's , car parks are all great stuff 

[monstermick58]

I wonder who's these loud pipes are then??






MMMM...... Very noice!!

Thanks Mick

That photo highlighted a small patch of soot I missed with my pipe cleaner, all fixed up now 

[braando]

So for now, I have put my baffler's back in and the sound is like the stock pipes

BAFFLERS................    ?        B...B.....BBBBBBAFFLERS.........?
Let me double check my dictionary before making a smart ars comment here "Woddy"     

[monstermick58]

Yes Teff Bafflers

    Surely a man of your experience knows what Bafflers are. If you don't I will explain.

BAFFLERS; The art of being able to dampen a loud noise while at the same time confuse a bloke who would normally make a smart arse comment.

Bafflers!

Ah! Yes, yes, I see what you mean, mmmm.... nice and clean  - take note Teff

Hey Sundog, thanks for the awesome recon on the bafflers and measurements. I will probibly take Rowdys advice and chop off the ends to start with.

Insert nerd here...if I recall my maths@uni dB is a factor of 10 log multiplier per bel or something like that. Meaning that a 25dB change in measurement would actually be a 300x increasde in sound power.

[goldFiSh]

The accuracy of the numbers will largely depend on accuracy of the measuring distance more than anything. Inverse square law applies here.

I'd be surprised with that differential, but there's more than a few factors at play here.

For the audio nerds.... Monstersonics.bogspot.com scroll way down and you'll see some comparisons of stock and aftermarket pipes on a roughly calibrated setup.

[Sundog]

Totally agree, the numbers mean very little in my test, it was the differential that was the point, that if you can imagine a 30% increase from baffled you don't have to burn bridges cutting stuff up to find out that it's goddam loud.
