Installed exactly 3 years ago, rubber coupling already rusted and broken. There were no problems with the installation, but fittings and gaskets must be purchased separately. Performance so far is as expected. This car only drives about 6,000 miles a year. The original part lasted 7 years in upstate New York where road salt is very aggressive. Four years ago the car was moved to PA where the salt isn't bad. Then I replaced it with this part in December 2013. Rust is no longer acceptable. GARBAGE!
