I have a 2015 R/T Plus, automatic. I have just added a JLT cold air intake and a Fastman throttle body. Next, I want to add a cat back exhaust. Been looking at Magnaflow, Flowmaster and Zoomers. I don't know how any of them sound, lol, but I want a good rumble when I step on it, and a little more when I start her up in the morning. I do NOT want to be annoyingly loud cruising in the neighborhood, etc. Oh yeah, I want chrome quad tips. Appreciate any input! Thanks!
