Remove the BARK not the BITE!

The revolutionary DB Dawg noise reducer is a unique idea aimed at 4 stroke riders using tracks and riding areas which are under ever increasing noise restrictions and find it hard to budget for an aftermarket Q or Enduro 4-stroke exhaust system to meet these noise limits.

Many people suspect that a noise reduction of this amount would mean power sacrifices, but this is proven to be untrue, we have dyno prints for two of the markets most popular machines and the power reduction has been well below 0.5%, in some cases only 0.15%.

Track Owners can stock these low cost exhaust inserts to have available track side and riders can install the dB DAWG within minutes and ride at their favorite track or riding area while helping reduce exhaust noise with no noticeable power loss. Don’t be turned down at the track because your bike failed the sound test, install the dB DAWG and RIDE!


How does the dB Dawg work?
Air will take the path of least resistance, but sound needs to hit something to be cancelled out. The dB Dawg insert has been designed in such a way (with the flat end and angled corners), so that when the sound waves hit the end of the insert, some of them cancel out and others bounce back into the packing of the muffler and are also cancelled out – this is also why you may need to replace the packing more frequently. The length of the shaft and the outlet hole are all exact calculations for maximum noise reduction and minimum power loss. Altering the insert in anyway will render it less if not totally ineffective.
Tuning with the dB Dawg
Installing the dB Dawg on some bikes tend to make them run a little rich which may cause a slight loss of power on the low end. Most riders leave the tuning alone and are happy how the bike runs. Whereas some riders drop the needle one position and make some fuel screw adjustments to bring the performance up.

dB Dawg FAQs

Which dB Dawg fits my bike?
 Measure the inside diameter of the exhaust outlet for external fit. Also measure the depth of the straight length of the outlet, which must be 65mm minimum in order to support the insert portion. Then check with the sizes below as to which insert you require.
