I just got off the phone with Wild Pigs and they informed me with a 2012, no matter what slip on I choose, the sound will not be affected because of the cat. Does this sound about right, they gave me a great price on cat less pipes and slip on! Just making sure I understand all of this before I order.

 

The sound really will be affected. It will be louder and deeper than stock. It just won't be nearly as loud and deep as with the head pipe, cats removed, breather, tuner, etc. I've had the same experience. Everyone wants to sell you Stage 1 from the outset. You'll be fine.

 

+1 to what KINGERS103 said !

 

Ran my CFR's for a month before installing the VH Dresser Duals. Huge difference in sound and volume.
