Managed to get this second hand Akra on eBay reasonably priced, I love the look and sound of it but I think I'm going to run it with the baffle in tbh just to save the hassle.
Put a baffle in mine, runs better and quietens it alot. You will need to drop the pipe off to fit it as the fixing screw is against the swingarm
Mine is near the bottom (see 2nd pic) so I reckon I can get it in with a short reach Allen key, only problem is the baffle is a bit chewed out of shape from the previous owner trying to get it out, it'll work ok but looks a bit naff from the back, I was going to try and get it fettled back into shape at work before I fitted it.
Looks a bit like the sane design as my m4 but the m4 has an s bend link pipe and is nuts with or without the baffle https://drive.google.com/file/d/0B58A9GJRyfaPUV9DeVFUZTFscGM/view?usp=drivesdk
Very nice, looks like you have a bit more link pipe but yes this is loud, seems louder on tick over than anytime else, I first fired it up in my garage and it knocked a plank of wood over that was leaning against the wall
