Exhaust hits Stabi

Moin, I have a big problem and need expert help. Have an exhaust from Mongoose on my EP3. He has a 70’s pipe from Kat. In left curves this pipe pushes between the middle and end pot to the stabilizer at the back right. Has this problem also occurred with other CTR drivers and could be fixed? Would not like to insert the pipe and without Stabi I also don’t want to drive. My workshop could not help either, they just loosened the end pot and pulled it backwards. As a result, the pipe did not come against the Stabi, but the MSD came against the holder of the Stabi. As a result, more annoying noises have occurred. After I have removed the pile from the workshop, it is again only the stop of the pipe in left curves to hear. Need useful suggestions to stop this annoying noise.
