I need to remove my catalytic converters. I have 4 of them. What's the best way to do this, and stay away from a Check Engine Light? Any tips on my project?

I have a 1999 F150 4x4 5.4L Auto Extended Cab 4dr
Magnaflow muffler, with dual exhaust coming from it.

 

Remove the cats, and get a 02 Eliminator. Do a search on here for it. Then, enjoy the sweeeeeeet sound and performance.

 

How many o2 simulators will I need? Also, after installing the Magnaflow, the truck wasn't as loud as I had wanted. Will doing this help with the sound?

But mainly, how many o2 simulators, and where's a good place to get them cheap?

Thanks for your quick reply!

 

Ebay would be your best bet... and I have no idea. I just used my Edge Evo to clear the code when it would pop up...

 

Just out of curiosity, which code did it give you? And how soon after removal of the cat(s) did it give the code? Thanks.

 

I haven't removed the converters yet. I am planning on doing it in the next few days, as long as I can get some o2 simulators that will do the trick.

 

I forget the exact codes, but it would give me two separate codes, both were for a catalyst system below normal somethingoranother. And it'd seem to come on about every 250 miles or so.

 

can u remove 2 of them the front 2 OR the back 2 with out adding the sims
