Just thought I would let yall know that I installed a FTE resonator RM4430A on my 2001 3500 with 4" straight thru with 5"elbow to 8" miter cut stack and it is well worth the money!!!! I honestly thought I liked the sound without it, but traveling over 100 miles a day towing our company trailer the dreaded drone got to me. I can finally talk, hear the radio(without turning it way up!), and hear myself think!...lol By the way I am no sales person for them, but had to give them credit where credit is due.
