In the past I have put several sets of Staintune's on my BMW's. (airheads)
Staintune no longer manufactures exhausts for the /7. The fit and finish was always perfect with them. I am interested in specifically the differences in quality and fit and finish to the Keihan's. I AM ONLY INTERESTED IN THAT COMPARISON. If you have knowledge of the differences or your experience with Keihan's I would like to hear your experiences but only with that brand. Thanks on the front side.
