Fitting an aftermarket silencer

Hello mates,
It's some time I have a question in my mind. I've got an aftermarket silencer to install on my SR, and since holes where bolts go through are not in the same place of original silencer ones, I have to made a special bracket.
I've made 2 pics in the morning, showing the more likely places to bolt on: as you can see #1 is the original silencer bracket, #2 is the frame's part where rear brake's stop nut is welded on. Installing on #1 means I'd have to make a sort of L-shaped bracket, with the L's "long leg" pointing toward the front of the bike; #2 means I'd have to make a much shorter bracket, as new silencer's bolting holes are under the aforementioned rear brake's nut. And I'd have to use some metal belt wrapping the frame to join it to the bracket.

Which one do you think could be better?
(Other solutions are obviously welcome!)

Hi,
Thanks to all for answering. Here are some new pics:

The upper part is where fitting bolts should go in, normally it stays on side, I've turned it up to show better.

[Blockierte Grafik: http://img23.imageshack.us/img23/3527/58635085.th.jpg] Same as before but viewed from the other lower side. As you can see standard bracket and silencer fitting point are only a few cms far the one from the other.

I thought to "L" shape because of this: the long L arm should be bolted on the silencer, while the short arm should be bent 90° and then bolted on the original bracket. Surely with 4 holes (2+2 as Hannsen says) to prevent the silencer from loosening.

As Wolfgang guessed, the silencer in previous post's pics isn't the aftermarket one but the original one. It's waiting for been cleaned, polished, and then carefully put aside... since the price to pay to have a brand new one 8o...

And... what about lenghtening the exhaust manifold with a tube? Doing so, I could align bracket's and silencer's mounting points and solve with a simple bracket to add... And, very important, I could gain some more gap between silencer and brake pedal, as I've seen that if I'd install silencer now as-it-is the pedal nearly hits the exhaust if fully pressed.

Cheers!

Target hit, Hetzer it's a Dunstall replica. I've replaced the poor inner glass wool with steel sponges (the same used to clean pots, like this) by stacking them on the baffle, hoping to help it to kill noise. How is yours built?
I've found a video showing a Dunstall replica installation: http://www.youtube.com/watch?v=VRuQtK3B408 . Right it's just half of an SR's engine, but the noise coming out without silencer is incredible anyway. There you can feel the difference too between old and new suppressing material. (That's to hope that it will work, obviously :D)

I'll ask a mate who owns a 48T about the pedal. In the meanwhile here's another pic of my bike

It's substantially a standard one, except for some add-ons (oil temp gauge, handle for centre stand, double direct lubrication) and mods (braided front brake hose, covered in black heatshrink to preserve the "retro" look).
I am now keeping myself busy with both silencer and carb, the first because of its price from new as stated before, the second because I've had quite enough of all its pumps - valves - diaphragms... Was thinking about installing a VM34-168 but I have to think well.

Cheers!

I've read various times on the net about burning steel, here I'd like to bust a myth (taken deliberately from Discovery Channel's "Mythbusters" :)) as not all steel sponges burns like most people think. That's all about sponge filaments' thickness: the thicker the filaments, the more difficult the sponge will set on fire.
I've realised a simple video some minute ago, here you can see the difference: the first sponge type is the kind I've used to cover the baffle, the second type is another kind I have close at hand. You can guess by watching that the first's filaments are a lot thicker than the second's ones, in fact only the second sponge gets burnt. There's absolutely no damage on the first sponge (just sooty) and it's been placed directly on the flame, a more heavy condition than the ones inside a silencer (at least, not so heavy I hope ;)).

Here's a pic of my baffle:

Yours, Hetzer, is covered with very thin filaments wool (a little bit thicker then the ones of video's second sponge I guess) maybe it's the reason why it's loud, as if wool is too thin it could plug the baffle's holes.

Cheers!

Perfect! Good to know. (You've got PM Christian :))

Update: I've got the 48T pedal pics but I haven't compared well yet, at a quick glance they look more or less the same.
I've bolt a straight chromed bracket that came with the silencer on and saw that its rear end stays just under the standard bracket. If everything works fine (not least, brake pedal's travel) I'll bolt on an angled bracket to connect the two.

Cheers!

Simone

Here I am again...
I've compared better my pedal with 48T one, I confirm that they look the same. So there aren't differences between 2J4 and 48T pedals... or maybe I've a 48T pedal installed and I didn't know

I've made a bracket from a piece of square-sectioned steel, I think 2mm thick is enough. Here are some pics, has to be finished yet - drilling and painting...
