Kind of debating on dropping the extra 2800 dollars if it is going to void the warranty.
Thanks for any information.

It all depends on your dealer and the relationship you have with them. In theory it will because it throws a big red flag since you are replacing the cat. Luckily most dealer probably will not notice if you change downpipes and keep the stock exhaust because of the location of the downpipes, this is obviously assuming you have a software tune to accommodate this.
