Few systems contain oxygen sensors that are connected beside the pipes (rear systems). After being conscious of these formulas, screw off the nuts and bolts from the engine header. Besides, locks are connected to the mounting brackets that need to remove. Place the nuts aside for the next use. Therefore, those studs present on the Harley Davidson need to detach.

Once it is placed safely, reattach the securements (nuts and bolts) tightly. Finally, check for leaks and footpegs to ensure you put nothing loose in the process.
