Today I got a custom cat back exhaust installed. I went with 2.5" alum-steel tube and a Flo-Pro Performance muffler. I also added a nice big 3" chrome tip. I chose the Flo-Pro because it's a heavy gauge aluminized steel welded design instead of that locked seam crap. I also did some research on flow data so here it is:
Ford Stock 215cu ft./min.
Flowmaster 372cu ft./min.
Dynomax Super Turbo 456cu ft./min.
FLO-PRO Performace 500cu ft./min. (As if I'm gonna need it with my 4.0...
Anyway... It uses a louvered interior pipe instead of fiberglass that eventually blows out.
Bottom line is, wow does it sound nice! Deep warm sound without waking up the neighbors kind of deal. Very distinctive and definately noticable in the cab when accelerating but hardly noticable on the freeway. Can't tell if there's any performance boost cause I'm running the AC all the time.
Here's the best part... $185
That's installed including the chrome tip and tax at Mach 1 Muffler in Spokane. I checked it out while it was still up on the rack and they did a great job!
