cut a pipe at right angle to a pipe axis
in the established situation the section can be made a chain saw
the section can also be made, having removed system
to remove the exhaust system, weaken a clip ahead of the average muffler and fastening of the left lower shock-absorber, also lower a back axis

Prevention
After work over the exhaust system check that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary weaken the fixing clips and adjust position of the muffler and an exhaust pipe, turning and moving them in the longitudinal direction to receive a sufficient interval and evenly to load fixing rings. Always replace everything самоконтрящиеся nuts.

Prevention
The carving of the oxygen sensor is covered by protivozadirochny structure. Do not allow structure to get to sensor cuts.
After work over the exhaust system check that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary weaken the fixing clips and adjust position of the muffler and an exhaust pipe, turning and moving them in the longitudinal direction to receive a sufficient interval and evenly to load fixing rings. Always replace everything самоконтрящиеся nuts.
