Just this past week I replaced the "suitcase" muff with 2 Magnaflow 14" muffs and removed the resonators and replaced with 22" stainless rolled/slash tips.
In a word AWESOME! It cost me $350 for labor and parts, and the sound is great. I ran it up on the interstate today and set the cruise at 75mph. NO DRONE!!!
It sounds like a big block now. Well, a big block with a small cam.
