M8 SE Stage IV 114 to 117 Kit

FL land shark:
 I have seen some information on another sit on the M8 Stage IV 107/114 & 114"/117 but no pictures of the CNC Heads or the rest of the Kit ? Just of the new header pipe w/o Cat and Street Cannon mufflers with cat in them to keep them EPA legal?

Heatwave:

Stock  TB yet?  I heard there is a 64mm for the kit .

What happens if you use the new header and use the cannons that have no cat???

You would have voided your warranty.  The warranty remains in force as long as you use only the parts that comprise the legal kit that has been certified to meet emission standards.  Substitute anything else and the result is an illegal modification that voids the warranty.

Of course this begs the question of why Harley decided to move the cat from the header to the mufflers.  My guess is they know it's easier and cheaper for customers to swap mufflers later on versus changing out the headpipe assembly, and they are still playing that wink-wink game they always played in the past by labeling kits and parts Off Road Only, knowing full well 90 plus percent of those kits and parts were used on the street.
