no. per the engineers at dynomax and magnaflow as long as you dont mod the hot pipe ( the one with the cats in it ) you do not need any kind of tune or programing modification.

What he said. Also, catback vs axleback will not make any difference. It just depends on the sound you want and personal preference.

This is absolutely correct and to take it further, we definitely recommend against modifying the cats at all. They flow great and its generally not worth the extra risk of fines etc if your delete them.

If you have any other questions don't hesitate to give us a call or shoot us a PM, we're happy to help!
