Does this really work?

If a chicken was too big then an egg may fit.....

Just chicken mesh does bugger all if you just stuff it up the hole. If you pull the can apart, and using mesh make a tube, and then, not too tightly, wrap it with glass fibre or such like. Wrap wire around the glass fibre to hold the whole thing together and reassemble.

If your only 2db over that should be enough.

Mmm, hoping for something as simple as "stuffing chicken wire in there, getting the warrant, then pulling it back out again"

ps: sorry Katman, have you on ignore, there's only so much dribble one can endure

Yeah, on a previous 4 into 1 on a GS million it was just TOO LOUD, so I tried stuffing some mesh up the hole, it made no real difference. Then I did the pulling apart thing and there was a noticable mellowing, took the "bark" off if it

I've you've got a spare duvee, you could try some feathers, that should work.

You don't need a workshop. You just need to measure the diameter of your pipe. Filling it is one screw hole only.

A couple of year ago i stopped in at a country pub on my way to the March Hare rally,went in grabbed a pint and went outside to find a gathering of bike people standing behind the TL peering down the right can,i had repacked it and added a layer of steel wool (thanks Loosebruce) the whole inner can was glowing bright red

Quite spectacular really.

Don't stuff that shit up there unless you want a metre long after burner flame out the back!

Pop down to your local muffler shop. You want the m to measure the internal diameter of your outlet pipe.

Lets say it's a 51 mm outlet (2 inch) and internal is about 48 mm. You require a length (150 mm will be fine) of smaller exhaust pipe that they can swell up to a outside diameter of 48 (to fit within the outlet of your existing muffler). A 38 mm pipe will work but they may be able to stretch a 35 - the smaller the pipe the less noise.
Once it's swelled up and is a neat fit in the end all you need to do is pop rivet or bolt it in place.

The reduced diameter of the outlet will knock off a few db - the length of pipe extending into the can will knock off more as the exhaust gasses have to backtrack to get out. You'll probably notice bugger all power difference and your neighbours will be happier!

Note just watch you don't drop the reducer down the centre of your muffler when fitting!

Goldie locks steelo pads sounds a heap more convenient. Pop em in then pull em out once its sorted

If you get them to weld a n M6 nut to the inside of the baffle he describes, and drill a 6mm hole in the lower part of the outlet spout, then you can remove that baffle any time you like

Plus you can drill extra holes in the tube, till you get balance of sound you desire. Steelo pads are bit more hit n miss.

For a quick fix, stuff crushed coke cans down the muffler. Easy to remove, although watch they don't remove themselves at high rpm

Strange.Everytime I've taken my bikes for WOF's I've NEVER been noise tested,and I use the LTNZ Orange place with 3 testing lanes.

**1wheel riot** · 16th August 2009, 18:40

it should work if its done right all it has to do is just stop the sound from going strate out.

**Boob Johnson** · 21st August 2009, 15:35

Baaa ha ha, got the WOF today!

How much did it cost you ask? How many arduous days n nights spent labouring away to dampen her wolf like howl you ask?

$5 for a twin pack of Goldy Locks from Woolworths & about 5 seconds to stuff them in

Tested it at home first, couple of blips on the throttle & they shot out, so stuffed them in a little further & hey presto! Didn't think they would last under actual load so pulled them out & shot round to the garage, stopped just around the corner, stuffed them back in & pootled along to the garage gingerly. Got the WOF no drama & when I left I fanged it up the road & they both shot out the back

Happy times

I remember that was pretty funny actually.. and we all know why they were glowing

Aha, I got smacked on the helmet by a Goldy locks earlier, that would explain it then

Well done but did they actually noise test it at your chosen WOF centre, I don't remember them doing it a t LTNZ, Oh well if they did it passed, cool, go ride.

Anyone have any experience with this?

Have heard conflicting reports

Just stuff the whole chicken in, its sure to make a difference.
