High Flow Cats?

Would replacing my 4 cats on my 99 F150 4.6, with High Flow Cats make the exhaust louder/sound better... and will it get me in emissions trouble?

Emissions should be fine but you may wanna check with the cat manufacturer and local laws. It will probably give you a little more exhaust note

Keep any paperwork in the glove compartment for when inspection time comes.

high flows will pass any tests. as for sound, yes, it will improve the sound. i had the high flows put on my 2000 and it sounds awesome now.
