i have these on my 2003 mach 1 when the exhaust was added. it is great to have because i dont have to worry about engine light coming on. my car passes inspection with no catalytic converter but i keep the car under 5000 miles a yr.
part was shipped fast and when i got it install was fast. I did have to cut the tabs off on one side but oh well they did what they said they would do and my car passed smog
Purchased these and ran them for about two weeks. Originally threw a P0240 code, the Eliminators fixed that code only to throw a P0138 code... My advice if you need your car to pass emissions, hold onto your stock H and swap it.
