Ok guys.....im in need for help....looked in this forum up and down only to get confused. ALOT....lol. I have an 05 FX4 5.4 it has 4 cats on it and there shot to hell....i see in all the posts here about high flow magnaflow ones with part number #94106.. But i looked it up and the cat is straight not bent on an angle like the ones on my truck?????? The cats closest to the engine are the ones i must replace and they have the angel built in to them. Is there a differnt part number forthem???? Or can someone please sent me in a direction to a replacement high flow that will work....Also if i cut the other 2 cats out will it trip an engine code???? I want to do this one time and do it rite, im not well off so my cash is very important to be used lightly hahah...thanks guys in advance. I hope someone can help me out....

 

Order 2 magnaflow 94106 cats. Take them to a shop and let them fab it all in. You should not throw a code, but it can happen. If it does there is a mod for that.

What is the rest of your exhaust system? A pair of 94106 cats will be much louder than your stock 4 cats.
