Looking at the thumbnail of your bike, I wouldn't recommend it. Putting a lot of strain on the exhaust flange bolts, plus I wouldn't trust the balance on the lift. I have the same problem on mine since I put the Delkevic 4 into 1 exhaust on mine.
Hi god no if you can use some 2x4 to each side of the exhaust you need about 12inch lengths but might need a thin bit off wood to level it .I have been working a lot on mine 1996 cb750ft and used wood on top the flat base bike jack .if any the wheels are off you need a strap to hold the wheel less side stop it tipping
Don't lift it using the exhausts
