I have a '14 R3t and my cats were in the OEM silencers, the weight difference is significant between OEM and TORs. Not sure about what if anything is in the box.
Welcome from Maine, search is your friend, you'll learn a lot by reading here, keep a log of the items you find interesting in Word Pad or something similar, sometimes it's hard to get backto where you once were, so notes help a lot,
