Yep J. you remove the mid-muffler aft of the Cat outlets. A 3" "Y" pipe is fabricated and attached to the cat outlets and back to the rear muffler. I had the mod done in New Mexico on holiday, it cost me a whopping $90.00. It makes an attractive set and the sound is throaty pleasant. It helped performance as well, especially fuel economy. As stated after the cool air ram intake, the tub gave me 27-29 mpg at 70 mph with A/C. If interested and Ashman tells me how to send digital pics through the forum I'll take and send a few.
