Does anyone know the decibal level for the HMF slip on and full system for the Z400's??

 

I do not know the decimal level but I know that they are loud.

 

anyone??

 

THey are LOUD, and their quiet core insert is pretty restrictive. We have one on a Baja and a Raptor, both with modified (longer, more holes) quiet cores. It's an okay pipe, good price, good quality, but not the quietest and not the best performer. It works better on the Raptor than the Baja, but everybody's pipe works better on a Raptor.
