So... I have a 1100 sport pro with the type approved termi. I love the sound of the exhaust on idle when the bike is started and also when going full chat above 4500rpm. But between 3-4000rpm it goes a little quiet, presumably for drive by noise regs, as this is when the exhaust valve closes. It shuts around 3000 and opens again just after 4000.
Annoyingly most of the city riding 30 to 40mpg seems to be in the quiet range. So taking a leaf out of Gasman (thanks for your helpful posts), I ordered a Healtech ESE-D01 off eBay for £40. Fitted it yesterday. Just to clarify I still have the OE mid pipe with the cat (for now).
Had to disconnect and remove the battery to access the connector. I've left the servo in its place, just disconnected it from the loom and plugged in Healtech gizmo in.
The sound is now a little deeper with no loss of the exhaust phut-phut sound. There does not seem to be any loss of torque or throttle response. The decel popping is the same as before, no louder or more frequent (which I feel is a shame as I love the sound of it and was hoping for more!)
All in all a easy-ish 20 min job which has improved my enjoyment of the bike when cruising at 30 to 40 mph. And gives me the flexibility to add a de-cat midpipe later.
