Good to hear!

The car I have has a single 4" sewer pipe running from the V merge in the engine bay to the tailpipe. The resonating sound gets old when city driving at certain speeds. (Maybe I shouldn't have removed all the sound deadening material.) :p
Anyhow, if all you hear is a nice tone from the back, great! Now I'm really on the fence about getting this.
