what i did costed me 6 bux...u get a turndown, disconnect the tube that goes from the cats to the muffler, and throw the dump in there. now my 5.4 sounds like my uncles '70 chevelle 454 ss....pretty effin loud if u ask me....and the car shakes everything, ive had ppl in stangs wna race me just cuz i sound fast...if u wna spend a lil more, just do a turn down and a couple of 45 degree and 90 degree pipes, and some tips behind ur backdoor, and ur set...

go a head and dump it by the cats and make it accrost the stoplight at WOT when its turing yellow....

you need some back preasure other wise you can say good bye to your torque.

just straight pipe it.

idk, ive felt some extra torque come up since i did the dump...when i hit it all the way down, the car picks up much quicker than it did before....and its louder than ne other f150 in my area

Ty

no, you hear it more, so you think it is faster.

if you were to dyno it efore and after, you would loose some torque.

but then again, the stock cats provide plwnty of back preasure for the most part, but if you go with high flow cats, you are going to want atleast a muffle if you are going to dump it before tha back tires, and no larger than 2 and 3/4 pipe.

everything is stock except for the dump, and its the same 2.5" as the rest of the tubing around...maybe your right, but i feel that ti gets up to 50+ faster than b4

Ty

now where exactly is it dumped?
below the cab, or before the rear axle?
mine is dumped before the rear axle, at about a 45, and I like it allot, and it has enough backpreasure, but that way you described it, it sounds as if you have it dumped after he y-pipe which would be boggy and loud as heck in the cab.

06f150lariat

yeah, its dumped basically under the passenger seat if you will....im going to put the gibson sport slash cut rectangular tips in front of the rear axle...it will probably sound a little bit better when i put the tips because i am elongating the tube size and such.

The tips will dive the exhaust a deeper tone.

06f150lariat

convincing enough for me...hey listen, do you think the brush bars would look good on my lariat supercab...in chrome since i have the chrome bumpers?

Ty

so you are basically doing what I have done.

take a look at my post about my exhaust tip for pictures,
