The exhaust pipe on my Nissan Sentra 2010 started rusting for the first year. For the 3rd year that I own the car the exhaust pipe rusted through the pipe and actually broke apart and is now hanging down. Now the exhaust is coming out where the rust came eat through the metal and is making really loud noises.
