Catalytic converter diagram ford expedition

Answer 1

Exhaust system. they look like a muffler.

Depends on what year you have. 1996-2001 are exact match with the Ford F150/250 under 8500 GVW. 2001 thru 2003 are unique to that vehicle. Post 2003 they changed again to a spin-form design and that design is good thru 2008. All have R/H - L/H cats. They bolt to the manifold and are married together at the R/H crossover pipe. I think the 2001 and later use a Torca clamp vs a U clamp so the crossover pipe connection is not ruined. 2001 and later have a 900 cell per inch catalyst light off can (#1) and can plug if you backfire with rich condition. Any oil additive like STP containing Zinc can plug your cat too. Stay away from all oil additives and spend the money on a quality synthetic or semi synthetic oil. Look up your model at Tasca auto parts.com. They have a wonderful database with many "view illustration"option. They have the best prices for OEM parts and a great staff that will answer your questions via e-mail or on the phone. Good luck. One last thing...do not try to run your vehicle without the cats. It will turn into one big mess and put your vehicle in "survival mode" You will be lucky to get 7 mpg.
