Quote: I have 40 series Flowbastards on my Charger also & got sick of the resonation while driving. I added the 18" Dynomax glass packs to the tail pipes like the factry resonators & man what a difference. So much quieter, no more resonating & my ears don't ring for hours after driving it for awhile now. Wish I would have done it years ago now.
Thanks for the reply! I have a set of the 18" Magnaflow glass packs and tips to get put on when I have the time to take her in to the exhaust shop. I am hoping I will have similar results!
