I think that it would be unwise to run the car without the exhaust support brackets as that will putt excessive load on the cylinder head mounts. The brackets you have highlighted fit the later type Polish exhaust as opposed to the earlier rounder exhaust.

I agree, I would advise you do not even try to start the engine without the exhaust system fully supported with the appropriate brackets. Don't even fire it up 'just to check', as the greatest torque of the unsupported exhaust system weight on the cylinder head elbows and studs will be when the engine first has to accelerate from rest to running. You risk snapping the studs holding the elbows into the cylinder head and that means the head off and drilling out the stud holes.

 These are the brackets you need for the exhaust you bought.

 The later type of exhaust is more oval and the brackets for them are different.

 I also like using these. They use to sell them as a kit with the nuts, but I can`t find one.

 The 126 engines vibrate a lot, so you need to make sure the exhaust is properly fitted otherwise it will end up cracking somewhere.
