|dietrichpfeifer||At one time I had thought about cutting curved slots in the stock baffle plate, and then making a plate with matching slots to go behind it with a set screw that would be adjustable. Then you could infinitely adjust (to point) the effect of the baffle.|

I'm going to take this a step further, because after a long run this morning I think it could have a bit more volume. I will drill some extra holes in the baffle "plate" so that there are more holes than just the central one with my cut down baffles installed. The drill holes will be the size of a bolt so that I can plug them back up for my yrly inspection.
This will give me truly "noise adjustable" baffles!

|GTRossi||love it! i always dig creative minds coming up with a new way to fix a problem. maybe you can drill a hole or two above the through-bolt in the short end of the baffles to make up for the free area the bolt blocks? that way you could run with the full baffles in, have a slightly more full and robust sparrow fart (duck fart?) and not choke up the exhaust...|

Well, obviously your "sparrow's fart" baffle is now even more restrictive than it used to be, so that answer is out for anything other than inspection.
I would certainly think that, if the shortened baffle sounds as good as the open pipe, just quieter, that is a perfect solution. Since it still cuts down the size of the exhaust outlet by about 75% (WAG), I would have to assume that it will restrict top-end power quite a bit compared to no-baffles, but, if it still has the big torque in the mid-range, I would hardly ever be venturing into the top-end anyway, just as I seldom go there now.

That is a very clever and creative solution.

creating Termi adjustable baffles
I love the sound of my open pipes, however there have been times when I wish I could turn down the volume without reducing the pipes to the sparrows fart sound with the baffles installed. I tried to source some alternative baffles without much luck, other than a $200 quote to custom make some.
Problem is I need to keep the stock baffles for the yearly rego inspection so I didn't wanted to modify them. Thought about it and then realised a free fix. As per the attached photos, I cut the pipes at an angle and drilled a hole so I could bolt the baffle back together for the yearly roadworthy inspection.
The cut down baffles, when installed, still give a great sound but at about 60-70% noise volume. This is exactly what I was looking for. So I now have three choices:
1. no baffles and beautiful full sound.
2. cut down baffles, lower but still beautiful sound -and my neighbours no longer leave dogshit piles on my driveway.
3. stock baffles with a sparrows fart sound, but acceptable for the yearly inspection.
I guess if you were after an even lower volume, then it would probably be an idea to leave more of the pipe length on the main baffle.
This might be a totally pointless thread, but it solved my problem about lowering the noise a bit whilst still retaining the stock baffles for roadworthy inspections. Oh...and it was totally free. Only tools required - a hacksaw and a power drill.
