has anyone ever changed there resonator if so which one? will a change of a resonator make the exhaust sound better? if you already have a magnaflow for say.

 

Vibrant resonators come highly recommended. Their prices are reasonable and quality is high. They also test their products to remove certain sound frequencies that can cause rasp to give you that smoother tone. Just depends on which size resonator you get. I installed the skunk2 header and it causes a bad rasp between 3k and 3500rpms and am looking forward to add a resonator to tone it down in the future.
