50 series or 40 series Flowmaster
50 series or 40 series Flowmaster
I have a 1998 50th Anniversary Edition F-150 with 4.6 and I plan to buy an exhaust system very soon. I want a mean tone and for people to hear me coming. So what series Flowmaster muffler should I go with, 40 or 50?
I want my truck to talk when I hit the gas. I am not really worried about interior noise. I also want a rumble when the truck is at idle. So 40 series is loud huh? What about that black Super 40 series muffler?
