As long as you have either OEM, AMP, Bestop, or similar power steps, you shouldn't have issue. The cat-back exits in the small sliver of bed just before the passenger's side rear tire, and most power step systems stop right at the cab line. That being said, if you don't the positioning of the cat-back kit quite right (or if you mis-trim on longer wheelbase models), you could have issues. However, most power steps aluminum step surfaces are extremely easy to trim.
