I took my bike in for my 600 mile service earlier this week. At the same time, I had them install slip on Termis and a 14 tooth front sprocket. Total installation and service was about $300, plus the cost of the parts.
When I went to pick up the bike, I asked if they had installed the db killers (to reduce the noise and keep my neighbors happy). The mechanic told me "No, about 95% of our customers do not want the db killers installed. Oh, and make sure you have earplugs on when you ride."
I rode the bike home from the dealer without the db killers installed. Luckily, I keep an extra pair of earplugs under my seat.
Holy $#!% were these pipes were loud! They sounded incredible, and together with the 14 tooth gear were probably the best changes I could make to this bike. I could easily tell a noticeable increase in power probably due to both modifications. The bike was a lot easier to ride.
Once I installed the db killers, the sound dropped dramatically. I would say it is almost equivalent to the sound of the stock pipes. I'm not sure I like it this quiet. I wish there was some middle ground.
So I put together my own video showing the sound before and after the Termis were installed, both with and without db killers installed.

Inside TermisTo anyone considering these modifications - DO IT NOW! It really puts the "Monster" in the name.
Enjoy!
