Exhaust ends for Next Gen Kits. You will need to cut out the existing exhaust port that's molded in the body and file the opening until the flange fits snug. You will also need to cut out or sand down the nub that i have circled in black in the picture above on the undertray. I did this in about 5 minutes using a Dremel with a cut off wheel disc and then filed it square with a diamond file. You'll want to file up to where the rocker line sticks out from the body so that the line from the rocker is gone. The flange will take the place of it and create a new body line there as you can see in my pictures. The outcome is much more realistic to to the real car.
