I have a 97 ford f150 with the 4.6L if i cut out my cats what will happen? If it sets of my check engine light can I get dummy sensers for it. If so where can I get them?

 

your best bet would be get 2 magnaflow high flow cats. No cats will stink really bad and your cel will come on. I bought 2 high flows and had them put on for $150 total, much better sound and emissions are lower than with all 4 stock cats.

 

If i put the magnaflows on my truck will it be louder and run better? my prob is that my drivers side rear cat is pluged up and it sounds funny. can i just gut out my rear cats and get away with that cuz i dont have the money for magnaflows right now.

 

Yeah you could do that, but im not sure if you will get a cel or not. Just do that and save to replace them.

 

ok cool thanks for the info I appreciate it

 

as long as the 02 sensors are safe & unmodified you should be safe

 

did doing this make your truck louder? I am looking to make my super 40 louder. I have heard that there are two cats, and two other things that make the sound quieter. Any ideas?

 

I cut out my rear cats and no check engine light. it did make the truck sound louder to.

 

the magnaflow high cats seem to be the way to go. i would think having no cats would cause all kinds of issues.

 

you can cut all four of them off and buy dummy plugins for your rear two 02 sensors because the first two sensors read before they go into the cats. go to dallasmustangs.com they are like $37.00 a piece and you only need two.
