High Flow cats

Will they give you a better deeper sound? Are they worth it? Will they mess up my emissions? Who sells them and for how much?

The stock cats on these trucks flow pretty damn well stock, so I doubt you'd get better sound.

You can't legally change them for 5 yrs/50K mi

CarSound is what I would choose for less expensive new cats. If you are hell bent on all power...Random Tech is the best.
