Pink Batts flammable/baffling pipes

[Deano]

Use chicken wire and steel wool at the end of the pipe to contain pink batts, stop it all blowing out ?

Can probably sort out the hook ups for someone in Christchurch, do you have any pictures?

Hi

I always go to our local fibreglass supplier to get muffler packing.
Pink batts is shit and burns, I used it in my 2 stroke once and 4 strokes
can get even hotter pipes.
For $10 I used to get enough glass sheet to do 2 sets of four mufflers.
It doesn't burn but is way cheaper than the bike shop "cheap" stuff.

Incidently suppliers of pipes often stock the original packing -
two brothers (wellington m/c's) do and it's the right amount of dense
seemingly good quality packing with rivets in this case.

Good packing makes a differences (I have tried about 6-8 types)

cheers

Ill try and put up some pics soon. Problem with buying baffles like that one betti shows is that mine are custom.. not just aftermarket custom. I paid someone to hammer them out and weld them.. wasn't hard to do in design.. I just dont have the tools or can weld. Because of this I reckon the pipes would be hard to find baffles the right size. They are approximately 2inches in internal diameter, but I haven't measured it yet.

Edit--

Thanks for all the helpful posts. I should have gotten onto this before the WOF expired.. but I just assumed the end pipes would be easy to pull off like the original stock ones were!

A pic of the pipes...

They, for the most part, are literally just open pipes haha

Just thought I'd post an update as this may in the future be helpful to someone else.

I took it to my usual bike shop.. only to find not only they don't do WOF they have nothing to do with exhausts and such. They recommended I go to Magoo Mufflers, as they did "quite a lot of work" for the shop I took my bike to. I got lost on the way there, and being nearby Radical Customs & Choppers I decided to pop in just incase they got anymore baffles in that were the right size.. as previously they only had 1 3/4" and I need larger.

Then I got the bright idea.. get the engineer at work to weld an additional sleeve onto the end so that it would be the correct diameter! So bought two 1 3/4" Custom Chrome chopper baffles. Engineer at work did the work within two hours and now I just need to take a file to smooth the weld spots, and drill in the most hidden place I can find a hole to put the bolt through.

Anyone know where in CHCH I could use a bike lift for awhile? I'd like to get under the bike to do the drilling and fitting if possible.

Pink Batts will burn after a while.
There is a high temp one,,its yellow. and will take the heat
Dont know about keeping it in there though.

Heres pics of the new baffles in the pipes. Not to bad eh

Took it for a 100+ ride today with another Chromed Knuckles member.

Sounded good.. worked well. Baffles didn't come flying out.

Had trouble getting my WOF though.. took to AA and they said my chain was too loose and that because they arent the original pipes that won't pass it. I appreciate the comments on the chain but the pipes are NOT that loud now. So I took it to the place Radical Customs & Choppers and while they passed me, they didn't do as thorough a job.

Funny that, I wouldn't mind them checking my bike over for any safety related thing such as my tires need replacing soon and the chain should be tightened.. but mess with my style and grrrrr!
