I like the Magnaflow systems. They have a nice tone when driving around town, you definitely hear them when you are on it but cruising down the freeway they are one of the quieter systems out there.
i agree, the CAT back systems they make are amazing. i took the dual side exhaust system they have for the hemi and had it tig welded on and sounds amazing but cruising has beautiful sound to it but not too loud at all
