ok i have a y pipe with stock cats no mufflers 3 1/2 tips turned out at 45 angle.... i want LT headers high flow cats and true duals definitely..
my question is what are the best LT headers ????? i hear alot about OBX but theres pacesetters and hookers out there to which are the best?
what kinda high flow cats should i get???
and for sound i want a good loud sound but deep also.. i also like trucks that sorta growl at you when you rev them up instead of popping they get louder and its sorta like a growl.. i love that so does that come from the muffler ??? or wat?? if it comes from a muffler wat kind will do it?? and should i have a muffler??? like i said i want a good LOUD but DEEP sound

my truck is a 97 f150 lariat 4x4 5.4l i always forget that lol sorry guys...................... oh and i posted a thread b4 this i just need to know like wats the best headers and everything i cant find a site to buy obxs from and i hear dyna techs the best but idk wat type to get and alot of people buy pacesetters... so my dilema with the headers is i want the best but dont know what it is and i want AMERICAN made lol

 

Dynatech is the best, but the OBX are identical them. High flows? magnaflow 94160. Mufflers? Imagine my set up, but with the aggressiveness of long tubes...

that sounds great but a lil quite.. love the sound but id like a lil louder muffler. i hear alot bout magnapacks then of course the famous super 44from flowmaster which i have on my 89 f-150 5.0l and i dont want them on my 97 so are magnapacks good and does borla make a louder muffler?? and if not does the borla muffler help ur power or anything like their exhaust systems do

 

...

 

Long tubes will make it much louder...

 

how much were the pro xs mufflers?

 

$99.99 on ebay. That took 2 seconds to look up btw...

 

If your going to run a factory tune or canned set, the OBX's are user friendly easy to install. Their not Dynatechs. Dynatechs have far better heat transfer, your exhaust noise will be directed out the rear. You'll get nothing under your feet. That's a real good muffler, but I would go with Magnaflow high flows in that 97, spin barrels. Use the OBX Y pipe. To keep your low end, stick with a 2.5 SISI. No CEL and torque will still be alright down low.

If your custom tuning, you have more options.

 

I wouldn't consider Dynatech the best...

American racing, kooks, and a few others are the best..

 

I didn't know Kooks made LT headers for the 04+ 5.4 3v?

 

They will make anything for the right amount of money...

 

Sorry didn't read the 1997 5.4 part... but FATHER do they make a set for 04+ 5.4 3v. I only found a set for the 4.6 3v... but they are shortys.

 

hmm right on guess I should of thought about the CUSTOM part in kooks custom headers! thanks for the heads up

 

Yea, you or a shop can cut and turn them to work. I can't recall which set to do this with. Fasterf150 has done it.

 

Cut what? They don't even make production LT's for the 04+ 5.4 3v motors. As FATHER said they will make a custom set for the right amount...

Correct me if I'm wrong. Unless you are talking about another set?
