I have read from a guys past forum that catalytic converters, if free-flowing enough, can actually be better than no cats at all...is that correct? Also, if that is correct, what is the best pair of cats to buy for a 4.8L dual application? (as far as sound and performance go)

 

the stockers flow quite well enough. if you are just set on getting some. carsound cats by magnaflow work very well.

 

Althought some people did not notice a difference, I personally thought it was well worth delleting cats.

 

my truck runs better without them as well.
