Looking where I can find a cat delete for my 99 expedition 4.6L can someone help me please

 

Are you looking for getting 2 cats to replace the 4 factory cats, or just get rid of 2 cats? There are different places you can get high flow after market cats like magnaflow or on ebay. I know a few people that have have cut off the back cat on each side and been happy with that. You will lose some low end torque, but they say the top end horsepower makes up for that, and you will notice it by not kicking out of overdrive as much. Whatever you do, make sure that you will still be abiding by tour emission laws in your state if you have any.

 

If you are just going to gut the cats and keep the shells for appearance sake you will need to get a tune to enjoy the best performance and to eliminate the sensors from throwing a constant CEL and codes.
