New to the forum and have some questions. Just picked up a 93 long bed f150 w/ the 5.0 engine and like most everyone on the forum I'm already planning my upgrades. I want to run a better intake along with a less restrictive exhaust. I'd like to use true duals coming off of either shorty or long tube headers(haven't made my mind up yet about that) but I've read on here that true duals still have to run down the right side of the frame between the drive shaft and the frame rails. Is this correct or not and if it is correct then why? Also need to know if long tube headers come with an EGR connection on the passenger side header for the EGR valve? If not how do you get rid of the EGR system? Or is it possible to weld in a port for it?

Thanks in advance.

 

I think 've already answered my question about the EGR valve. It looks like it doesn't connect to the exhaust manifold so headers shouldn't be a problem.

That is correct, but if I were you, I would not run true duals. A little homework will tell you why, but it is the same reason that triple y headers will outperform longtubes. It all has to do with the Bernoulli effect. Dual exhausts do not flow better than well designed singles. Those who argue otherwise are not comparing apples to apples. Dual exhausts are used on musclecars because of the sound they produce, and because those kind of applications do not need to rely on low end torque. They also have equal lengths, and have other tricks to maximize top end power.

If yo want the look of duals, and want some extra sound, a good single inlet dual outlet muffler combined with larger tubing will produce a similar sound, while keeping the benefits of the single exhaust.

 

When I did dual exhaust on my truck I didn't do it for the power,I did it for the sound.It is in my opinion that you can get a better sound out of a true dual exhaust system.It may not be equal length true like on a mustang,but if i'm gonna have 2 tailpipes they damn sure are gonna be true and not coming off a 1into 2 muffler.

 

Some do a sorta hybrid system ... Dual exhaust with an "X" crossover before the mufflers ... I would not suggest the "H" crossover ...

 

Not trying to be a smart @$$.
But, if you already know the answer then why are you arguing with
everybody that is trying to answer your question.
Seems to me that you already know what you want to do, so do it.

Dual exhaust is not for power, its for top end speed.
A good single system will give you low end power.
If you want it merely for SOUND ??????????, then whatever will work.
BUT...a Flowmaster muffler on the stock pipe or a good single is the
cheapest and easiest way to go.

 

Who was your reply aimed at? If its at me then you are wrong. I don't know exactly what I want to do nor am I arguing with everyone "that is trying to answer my question". I asked several simple questions and as of now still haven't had an answer to them. First, do all dual systems have to run down the right side of the frame and if so why? Second was a question about the EGR valve which I was able to figure out myself.

 

OOOPS...
Sorry, I thought you were 97FRD1TN.

Anyway, yes you can run duals and no they dont need to run down one
side of the truck. If you run a 3" single pipe with a Flowmaster 70, you
will get good low end power and you can get a FM kit for about $300.
If you go with duals, you get mostly high end rpm speed, about $400.
The muffler shop will have to do more labor to bend pipes for duals.
Same goes for headers: shorties are made for speed and long tubes are
made for low end power. Tri-Y long tubes are the best of all headers,
they give you the best of both worlds. When you order headers, you
can order with or with out the emissions bungs welded onto them.
I highly recommend getting ceramic coating to reduce temps. under hood.

I use K&N complete intake system with Gibson tuned stainless ceramic replacement headers, Flowmaster 70 cat back system and FULL 100% synthetic oils throughout. This allows me to run with less restriction, friction and lower temps. in the engine. With the added benefit of getting about 20 more HP and 3 more MPG on average. No company offers any
long tube headers for my 5.4 Super Duty truck.

My oil change interval is 15,000 miles with good filters like Mobil 1 or
Royal Purple synthetic filters and Mobil 1, Royal Purple, Redline or Amsoil pure synthetic oils. Only these oils are PURE synthetic oils, period.
Any of these are great to use.

It is not going to be cheap, put some $$$ aside.
Hope that I helped you.

 

Thanks man! Great answer. I think I've made up my mind to go with a 2into1 system cause I know that will give more torque on the low end. And Flow Master is where I'll be headed for the muffler and pipes also. My question now is whether or not I keep the cat on my '93 or maybe get a newer cat that is a high flow one.
Again, thanks for the help.

Mike

 

LOLOLOLOLOL.
Cool beans.
No matter what you do...
Please do not do anything illegal.
Like no cat or no muffler or no egr, etc.
