If the replacement changes the whole stock system, remember that the exhaust system involves the engine ports (exhaust) in the muffler.

The next step is removing the old pipes. Remember one thing for the customization; they are, floorboard and fender need to detach if needed. 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. Now, the exhaust pipes can be slide off. Be noted to keep them in a safe place. You never know if you’re going to reuse the exhaust. 

Step: 3 

It’s time to install the new system. You must be done removing the old exhaust. Though you’ll be provided instruction with the products we mentioned, it is essential to maintain precautions to never damaging the new pipes. Doline up the headers properly by pushing the pipes back correctly. Be careful if the engine’s cylinder (heads and ports) is maintained in guts. 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.
