For 2:1 Redthunder Exhaust Systems
Not Fitting any 2 in 2 system or any other brands exhausts system.

It comes in a set of 1dB Killer and its 3 mounting bolts.

The dB-killer is meant to be mounted at the end of the Silencer. This "tool" makes the opening of your exhaust smaller and therefore it makes your motorbike produce less decibels.

The dB Killer Standard is the street legal one. Internal tube Diameter 2.7mm.

The dB Killer Medium, also called "racing" is not "street legal". Internal tube Diameter 3.7mm.
It allows your exhaust to be a bit louder than with the Standard one. Because we know you will be asking... "how loud?", we can't really say it as all depends on the bike you ride and the engine stage you have, but one thing is sure, it won't sound less loud than the standard one, in  all ways.
