I just got 33's for my 5.4 4x4 and I found out i have 3.31 gears. I plan to get the 9100 tuner to help me out very soon. What exhaust setup would give me the most low end torque? I am gonna need as much as i can get to turn these tires, since i dont want to swap out my gears. Thanks for the help in advance. Oh yeah, i want it pretty loud(not like open header loud). I dont care too much about drone. I just want a loud deep sound.

 

Did you Fit 33's on a stock 4X4 F-150? If so what kinda tires u runnin on

 

I havent mounted them yet. I got the terra grapplers. And yes i am leaving it stock height. After I mount them I will post pics of trimming and ect. The tire size i got is 305/70R16 on a 16x10 wheel.
