So I measured my DB. Who else has done this so we can compare.

I'll have mine remeasured tomorrow, as I have forgotten the idle and the rev numbers though lol.

If it stops raining I'll test mine again as I can't remember the figures but seem to remember tick over around 98, but check this link out to get an idea http://youtu.be/pSKocP_cg5I

Just copied this from another post in this section, only thing is that the DB level checked was with the normal baffles in as well as HK Quiet baflfles installed as well. He checked it and measured it at 2 different RPM's with V&H Cruzers

The db meter that comes for the IPhone-4 is actually very good source for db levels.
My mate has a proper meter and we cross referenced it against the IPhone. What we found is that the meter gives a very good reading of db level. When placed near to the exhaust but out of the flow just behind the end of the exhaust we found with the V&h Cruzers and HK quiet baffles was that it gave a db level of 95 at tickover but 110 at 3000rpm.

I put my iphone on a stool about 3 feet above the exhaust. DB app read 94db on tick over and 101db at 3000rpm.

Unless we all decide the distance for the measurements, this exercise is no good for comparison purposes.

Yup, that too.

Apparently:
Quote :
Position the sound level meter exactly 20 inches behind and at the same height as the motorcycle's exhaust. The microphone must also be parallel to the ground and positioned at a 45 degree angle when compared to the motorcycle's normal line of travel
Ignoring the fact that the sound meter should be calibrated etc and people will use different ones, that's as close as we can make it I think.
Also would be good if the measurement was taken away from closed spaces, walls etc, so the sound doesn't bounce.

Moved from just above Marcins last post so as to slightly change the text

Also check what your appliance says with regards to this and the app that you will be using. What is right for on will be wrong for another

That experiment has proved 3 things? 
1.. my garage now smells of exhaust fumes. 
2.. my neighbour has no sense of humour ? my dog is bigger than his though, so no relevance :shithhappens:  
3.. 94db tick over 100db at 3k Embarassed 

oops sorry! 4 things? Jo is convinced I'm not normal

So what generic distances are we all going to use then? just been reading that db readings should be taken at 1-3 meters from source and not directly at source so with that in mind shall we say to take an accurate comparison we should all place our meter at 1 meter back and 1 meter to the right (when looking at the rear of the bike) and also in an open space so as not to get to much resonance, two readings to be taken i.e 1st @ tick over and 2nd @ half throttle.

How does that sound?

Hmmm anyone know where you can buy, at reasonable cost, a db meter that goes beyond 110db as this is as far as my iPhone app goes?

Sorry martin I am no help here as techy things loose me but I did just search and see that Maplins do a meter that runs to 130DB but that ain't cheap it's £29.99 so probably not what your looking for as it will not get enough use to warrant the cost, Hopefully someone will have a cheapo idea that lots can use

Martin I think you may be suprised as DB's are funny how they are worked out, 130db is not 30% louder than 100db to think that it is 30db level louder when you consider it against 100db is kind of wrong it can give the wrong impression. 130db is many times louder than 100dbs i believe


wikipedia wrote:
On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB.

My test failed !!! my windows phone wouldn't record anything over 70db probs down to the microphone !!!

Just done it with the ipad and got 99db at idle and errrr......well the meter only goes to 110db so its errrrrr well louder than that at half throttle  !!!! lol

Note: my pipes are standard with the baffles removed.

If you like the look of the standard pipes, you should check out the pipes i fitted on my Slip ons thread.
 K02 Silvertails custom pipes. I think there the mutts nuts and with the baffles out they are REALLY LOUD.

I have 8 - 1/2 inch holes drilled in outer plate. First baffle punched out with 1 inch rod.

96db vs 100

Everyone of the guys I ride with say it sounds good.

To me, the solution is very simple. Knock a few holes in the end plates, and enjoy.

Hi Rattler   I've no got six holes per end-plate but bafffles intact. Sounds good around town and up to (say) 55mph, any faster and wind noise takes over. Have left baffles due to concerns about MOT and re-sale value, as once their damaged, there's no going back

Holes drilled in the end plates can easily have a circular plate put over them like Bluesman did when he traded his bike back in and the holes being put in the internals with a long rod make it sound nicer but can not be seen & mainly just change the pipes to sound better but do not sound like an exhaust that has a leak so both are ok. As for the MOT, no problems have ever been expressed by anyone that has ever done either

Thank you for that, Captain. I've returned the heavy hammer (to a Bandit owner) and the long spike (to a Beemer owner), because of my MOT concerns. I now have to agonise all over again. Shall i, Shan't I ? Driving me mad.  One quick question. What are the 800's baffles made of ? It's been suggested to me that they could be stainless steel, and therefore, there's a risk of knocking the end off into the exhaust, causing an unwanted rattle (a well as the better sound). True; false ? Ta 
PS I had to borrow said instruments, as oiling a clutch cable never needed such equipment, and I've never done anything since !!

Clive, if my Jardines got MOT'd then I don't see how customised stock one wouldn't.

As for the internal plate...why noone does this with a long ass drill?
Something like 60cm should be long enough? Then you're not risking bending anything or knocking it off or anything like that.
Food for thought.

I would only use a drill bit that was being used in a drill, not to be hit as it has no point so would need to be hit much harder & it could possibly cause just a big dent/bevel in the plates before making the desired hole. It's possible that depending on the way they are put together internally that hitting with a blunt object could cause other damage that so far hitting a hole with a long pointed bar has not shown up or done.

Well as a expensive lesson, I've stripped the standard pipes completely,from the end working ire way to the pipe into the baffles you have the tube baffle welded to a plate with holes in.behind that is 2 further plates and on the very end is a round thick mesh filters that's in the intake pipe. The r pipe is easy to clear the other has a little bend which is how I put a hole in the side of my exhaust......doh! In my opinion it's easywe Tobuy some decent after market pipes and it's easy to fit them than muck about with the standard ones !
