There is a solution to this, you know. Install cutouts. I run about 18" of 3" pipe off my headers (3" flange); then a set of 3" cutouts, then down to 2-1/2" out the back. I drive to the track, 5 minutes to open up, and away I go. 5 minutes at the end of the night to cork back up. With the old 383, I actually went faster with this setup than open.
