I'm looking into putting true duals on my truck. The person doing the says to just run 2 2 1/4" pipes front to rear. He told me he would run it so that we could install 2 Maggies later if it was to loud. How does this sound these trucks.
BTW I will still have all the convertors.

 

Sounds like a good plan. 2 1/4 inch is the way to go

 

Id go ahead and put the maggies on, but it will sound good

 

my van gets compliments all the time- stock cats- 4x9's true duals xpiped-phil

 

X2 i get more compliments on my exhaust with maggies than i ever did with flows. 14in round magnaflows true duels.

openclasspro, i remember you saying you gained torque with troyer tunes and true duels,did you dyno it and how much did you gain?

 

i didn't dyno before exhaust and tunes but my 04 5.4 2 valve rear wheeled dynoed 300 ft lbs of tq at 2500 rpms and damn near stayed there till 4350 roms where it dropped to 278 rw ftlbs tq that is a very flat tq curve- NEVER did i see a stock 260hp stock 2 valve 5.4 make that flat and abundance of tq- it moves my 8000 lb van around spiritedly-btw- my stock 06 same style van- much l much light gets trounced by the weight laden van- tunes , duals,pullies, and drop in air fiilter- my .02$-phil

 

ive got true dual with the 40 and an X pipe out the side i love it. check out the clips and turn the volume up!!!!!!
