I talked to two different techs at Flowmaster, said I wanted a muffler
that would flow the best with most HP/TQ gains for a 2001 4.7, not too
worried about in cabin noise, and both pointed me to the SUV 50 Series
muffler. It has one of their largest casings for more flow.
I have it on my truck with dual 2 1/2 inch mandrell bent pipes (get these
-vs- press bent) dumping into 4 inch angle-cut tips...sounds great and
indeed has some nice throttle response.
