Not difficult. Our 3" "Silver bullet" round cats fit the sidesill perfectly, no "square peg in round hole" jockeying. They are shorter than stock by a goodly amount, allowing much lattitude. Just cut off the reducer and butt-weld the cat "WITHIN THE INSULATION COCOON" where it belongs. Centered is better.
Since you bought em from us, we are happy to send any needed extensions , etc, if any, for a nominal charge.
Even tho the cats run much cooler than stock, you might considet spraying the sidesill interior w/ HT-1500 paint to help protect against discoloration of the sill paint.
