On the Dyno the Bonnie produced an 8 Horsepower gain over standard. That is just with the pipes and no engine modifications. Customer feedback also reports a huge gain in mid-range performance and throttle response.
I want to know about the sound:
Ask any Trumpy owner with Staintune’s and they’ll tell you they sound great. They also bring out that distinctive Triumph note. The Staintune Teardrop replicas are ADR compliant and come with Staintune’s removable restrictor system.
Restrictors in: 90.5 dba @ 3650 rpm
Restrictors Out: 95 dba @ 3650 rpm
Have a look for yourself, they look magnificent and will last the life of the bike. They come in a mirror finish that you can see yourself in and with a little Staintune Liquid Mirror Polish they will stay that way.
