Apart from modified stock,it's easy to quieten down aftermarket pipes. Take out the baffles and wrap fibre-glass stove rope or ladder tape from a heating supplies firm around the baffles, fix with wire and refit. This is a universal method where you can get any exhaust down to any volume you require. I used it very successfully on my HH Short Cuts. Quiet baffles are available commercially but will give a fixed db reduction. You will find all the info available by searching this section. Hope this helps.

Best way to quieten after market exhausts is to put the originals back on lol.

That's not quiet, that's silent  

I dont know how this solution is as a permanent use, but i have used it for the inspecions that needs to be done one motorbikes every 2 years here in Sweden.
I have a pice of pipe with the same outer diameter as the pipes have inner diameter.
One end has a welded bottom with 10, 5mm holes in them. 
I put 2 of those metallic "balls" that is used for cleaning, like "metallic scotch-brite", in the pipe.
The inner pipe is fitted at the end of the exhaust and fitted with a screw that goes through the exhaust pipe and in to the inner pip.
This reduces the sound level enough to pass through the inspection

Good little cheap mod Twenty2.

Thanks alfie

As i said, i dont know how it will work on long term usage. But it lower the sound level enough to get passed through the inspection.

Nice one Twenty2 always better to make something up if its just for a purpose day rather than permanent and even for permanent use some times when it is a simple modification   

That worked well Twenty2.
