Staintune finally returned my e-mail and said that they did manufacture a crossover (which they call a collector), but they stopped production over a year ago,,,but they have none left in stock now. Huh,,,,wonder who bought the ones they did make?? Must be all those people who didn't want more power out of their Touring
I'm still waiting to see if someone can give me dimensions of the stock Roadster crossover, cause if they are the same inlet-outlet diameters I may chance the Roadster pipe.....although I didn't ask price yet
