Hi Dale,
I dont believe they make 'special's' for the likes of the Daytona. I use the same principle to make 'one-of' applications for various race cars that I build. The design is quite simple & effective for noise reduction without hurting performance. It would not be too difficult to fabricate sidepipes that look like the original and incorporate this design.
