Interesting that you mention that you're returning to the stock exhaust because of the "loudness" of the FI CBE. Was it the noise of the exhaust itself or the drone or both that you found annoying?
Can anyone comment on whether or not the 18" resonators "significantly" reduce the noise level compared to the 12" resonators? I debating whether to go with the Stillen CBE or FI with the 18" resonators. Can anyone comment on which one is likley to be quieter as well as less prone to drone? I recognize that noise aesthetics and tolerance are highly subjective. What is annoying to one person may sound like a symphony to another. I'm simply looking for a relatively quiet CBE based on the choices that are available.
Thanks!
