This is all you need - the junction. You don't have to replace everything...

no sir will have to fab up your own. Your are legally allowed to replace cats if they have failed.

A bad factory cat can be replaced, I put two Magnaflow cats on my truck because a bad tune fouled all 4 of the factory cats (I just gutted the pre-cats).

 

[mustangrfast88]

did you have to get mil eliminators or a retune since you gutted your pre cats or did it hurt anything and how loud is your truck

No retune required...the sensors for A/F ratio are ahead of the pre-cats.

The sensors that monitor cat performance are after the main cats, so no codes either.
