I finally installed the Staintune "Slashcuts." Definately toned down from the Bub's. Of course, I did my best to tone the Bub's down (packing material, & small end-pieces). But these Staintune strike a delicate balance between various government agencys & a really intriguing exhaust note.

I'd say the decibels range in the mid 90's.

"Speedmaster" is a title not a name, - and the title is not plural.
