honnest i have to sets of k5s on my truck and i would love to know what the real db rating is… i heard like 167?? not to sure… i know its loud i looked online to try and find it but cant find anything…
115db at 100ft with 125psi. All the claim’s with higher db’s are probably taken at a closer range…like 5ft. 100ft readings are the standard of measuring db’s.
