Exhaust Headers fixing / fittings ~ bolts wanted Empty

I have fitted my Termi, complete with U connector pipe to the 2 downpipes.
My problem is that the bracket supplied has no fixings / bolts(?).
Look as if it should be a pair of steel bars, one threaded with a bolt running through, akin to other exhaust fixings I’ve seen.

see below photo…

My question would be, where can I get these??

They aren't sold as a separate part. You could probably make something out of bar but it would require some buggering about.

They're still available I believe. Why not just buy one. It's not like it'll be a regular purchase.

Pete,  on closer look this part appears not to be a Termignoni clamp.  I believe the U-connector mid pipe is part of the oe system.

The Ipothesys pipe that I’ve removed had its own integral mid-pipe, which connects to the headers with a pair of separate clamps.  As seen below…

I thought of reusing the above fixings but they’re fixed into the clamps.

I ordered some stainless t-bolt/Mikalor style clamps from carbuilder.com, fwiw.  Measured and ordered closest fitment.  
That said, OEM is probably heavier-gauge/more resilient.

The OEM clamps (GU06123401) seem to be available from the usual Guzzi vendors but do not come cheap:

AF1 (USA)

Stein Dinse (Germany)

TLM (Netherlands)

I would not use stainless fittings anywhere on an exhaust fitting, because of the likelihood of galling.  Don't ask me how I know!

Dave, please explain what you mean by ‘galling’?

Do a Google search 0n stainless steel galling. You will get a better explanation than I can provide.

Read about it… Wow! Up to 40 years ago I was a Marine Engineer, and I’ve never heard of this, or have I forgotten? 🤔 Learn something new every day. Thanks

Yes def not cheap @ £87 in uk, and €85 in Netherlands + carriage.
As Pete said earlier, no separate parts available. Fingers crossed that a search by previous owner proves successful.

Measure at 57.5mm diameter, so I’ve ordered a pair of Mikalor stainless clamps for £7 …CopperSlip will be used 😉
