I know that all of the viper pipes make nearly the same power. Which ones are the quietest?

i would say SLP's gotta be the quietest, those things almost sound stock on the noise level

SLP
, then Simons CPRs

slp are quiet,i think aaen would be in second place,at idle and light throttling they sound stock but when ya stap it then you know something has been done.
