Great Job Barney :yup:
Yes, my pop riveter similar to above. Helps to have large hands.

Thanks Barney, Delw.
Yeah that's the type I have, but not a swivel head, it's probably just be an awkward angle or strength thing for me & having to use both hands. I'll get a swivel head one which may make the angle a bit easier.
Thanks again.

Bought this as it looks like I can stand over it and use both hands, should make it easier with stainless rivets hopefully.

1125r Torque hammer exhaust striped & repacked.

I wondered why this exhaust was so bloody loud, it was absolutely packed to gills with wadding and acting like a straight through. There just isn't any point in having a perf tube if the gas just travels along it without being disturbed, it might as well be a straight through pipe. No complaints about build quality, just built to last rather than being repacked which I guess suits most people. Gave it some breathing space which should quieten the FFFer down a bit see pics.

Bloody pop rivets are the wrong size. Unfortunately I couldn't tell till the old ones were out which is gonna slow the test down a bit.

Put some alloy ones in & polished them, runs fine, still noisy on tick over & setting off but not when I'm going faster. It has a nice deep & rich note that is easier on my ears, also smoother pull through the gears which all works fine for me. Was it worth doing? Yes.

If I remember correctly the Accoustafil expands a small amount when hot :?:

the acoustic science escapes me :old:
something along the lines of the sound waves resonate outwards from the gas path which is as straight as possible ...

I suspect a grown up will pop along in a minute & explain it better :mrgreen:

looks like it worked though Paul :sun: :yup:

that silencer I did the other day, blew the wadding to shit after two 40 mile runs ha ha. Sounded twice as bad half way through the second run.
Rebuilt it again but tried to do right this time, (stuffed to the gills). Hopefully get out on the bike tomorrow to test and well see.
Good experience though & the new size stainless pop rivets arrived so looks tidier, (stainless lining for me.)
The silencer had done probably 6/7 thousand between bikes hence all the filler was caked & burnt & not really baffling.
Should work this time :shut:

I used Demon tweeks online guide as to how much packing was required to give enough room for correct expansion . as too much packing can be same as not enough and result in a noisey can .

Honestly Barney, this can was absolutely stuffed solid, so I've done that again & added some 304 fine mesh round the perf tube to stop it blowing the crap out of the wadding so quickly. It's how it was built originally so here's hoping. No doubt I'll find out later. Thanks for the input though. Paul.

Seems to have worked ok.
Bike has just gone through it's MOT this morning, I asked the guys if I needed the DB killer in, he just shook his head, they're pretty lenient with exhausts but not much else which is great.
Time will tell I guess but for the moment sounds nice & performs well.
