   Good quality, had to buy extra baffles as they were quite noisy but now bike sounds great.

   See my other review on the Dunstall silencers. I found them a tad too loud so bought and fitted these. They do give a subtle but welcome reduction in the noise level. But I felt the need to do some fiddly DIY mods to fit them. The self tapping screws that come with them just don't look like they'll stay put for long (I may be wrong) so I drilled out the pipes and baffles with 5mm bit and used some M5 nuts/bolts/lock washers to secure them. Doesn't look too ugly and much more solid feeling fitting. Had to remove the pipes again to do this. Would help to have a photo with them fitted and some fitting instructions. I would have preferred if they could be fitted further inside the tail pipe but cannot due to position of fixing hole. So they do look a bit odd……hence the 3 stars.

   It was easy place ,using a 4 mm bolt to fixed the decibel killers.
   The Decibel Killers take a little noise a way ,expected not too much of it

   Fits perfectly in Dunstall silencers. Screws are not nice, replaced them with 3mm round headed stainless and nuts.

   Hi can't fault your service spot on ,the actual decibel killers are not that affective at lowering the noise and had to be drilled to fit a decent stainless fixing bolt instead of the cheap self tappers that came with them however in saying this I will buy other bits from you in the future .

    I recently got the Dunstall pipes and while I like them, they sound a bit "raspy" to me at higher rpms so I got the Decibel Killers hoping to mellow the tone a bit. They make a very slight difference but not much. It's a slight improvement. They were easy to install. I had looked for reviews before buying but could find no info on how effective they were. Where are all the reviews?

    What a great sound!
    10 year old Bonnie brought to life.
    The decibel baffles will keep the neighbors happy otherwise it could be a bit loud.
    Quick delivery easy to fit ( if the original nut did'nt spin in the metal)
    Getting it mapped next week then out and about
    Cant wait
