I replaced the front pipe in June because the flex pipe rusted out but the rest of the front pipe is good I keep it for now. The muffler is louder bye a bit has some rust on it does not look as nice as it should so it will be next to go my luck it will be the winter. Mine is a 2008 I bought it in June 2008 so it over 5 Yrs but I only had it for 5 Yrs two Months. The weather where it sit be for you buy it after how wet the area is how much rain it's been drove in how long it sits before it drove again.
