All of the expensive coatings just make them look good, and are to reduce under hood temps. I haven't had a problem out of mine yet. Check with summit racing and they might be able to tell you with some certainty whether or not they'll work with the front half of your 85 setup. My guess is that they should work.

Is your truck computer controlled? O2 sensors, and all that might be affected, if that's the case.

Alright boys,
My dad says that its somewhat computer controlled, I believe otherwise and say that it is not computer controlled. And another thing now, my dad says that it will cost around 500.00 to do a whole exhaust system from front to back, which i find horrible hard to believe. Headers for around 100-200 then add a dual exhaust system part for what 100-200? theres no way that it could come to 500 is there? I don't think so, But i'm sure i could be wrong. So what i'm asking is, can a dual exhaust set-up with headers cost around 500 or more? And can i just run headers for a little while and then convert to dual exhaust, as you guys know, funds get short. I just want the basic set-up. And if i can only afford the headers for now, how long should i run the headers on the regular stock single exhaust exit?
thanks,
nick

If it had a 302 originally, it would have been electronic fuel injected. That was the first year for it and eec IV. From what I can tell, there really is no difference between 1985/1986 engines, and the later versions.

I have the same summit racing headers that Hotrod has on his truck. They are cheap, and not coated, just he said, and I've had them on for almost 2 years, with no problems, or leaks. I have had to tighten them once, and I probably ought to again soon. I just have a cat-back exhuast, and I think they'll perform a little better with a true dual setup.

Are you going for full-length or shorties? I have the shorties on my 93, and what they do is bolt in place of the manifolds. Full-length is obviously better, and depending on your area, are worth the extra $$$$$.

Are going to install a better exhuast system?

This is what my system cost me.

Summit headers: $159.99 + 6.95 SH.
Flowmaster Cat-back Dual pipes Single muffler: $237.00
High Flow Catalytic convertor kit $175.00

So, as you can see if you build it in stages you will end up spending about $500, but if you do it in stages you can save up to do whatever you want with it. I didn't know just how good mine sounded until the other day. My brother took my truck down to the store to get some cokes, Man that thing sounds good!

Pastmaster,
That is a problem with my truck, I do not know what it had in the truck orginally, And mine is on a 2 barrell Motorcraft Carb. So your saying to get the full length headers? In my area I do believe that I don't have to worry about emissions. So Whatever is best i'll try to get. But I would like ot get the full length. And yes I do plan to get a full dual exhaust system, haven't decided to get true dual exhaust or just cat-back.\
Hotrodford_88,
Thanks, I'm sure it sounds bad #####.
thanks,

Actually you would be surprised how fast you can total up $500 dollars doing an exhaust system. I had about $850 into the exhaust of my old 90 F150 351/5spd. That was from engine to bumper and everything was new.

IMHO Thorley is about the best header that you can get unless you go with a custom header or Bassini. The Thorley's have a thick flange that prevents warpage and a terrific gasket that really seals nice. Make sure that you use a good gasket, ROL probably makes the best on the market and Buffalo (used by Thorley) is a close second.

You can get the rest of the exhaust for less than $500, but you get what you pay for. A friend of mine did his exhaust for $200 and the pipes turned all rusty looking within 6 months. I've had my aluminum pipes and Thorley headers on for 18 months and they still look great. I have a true dual and had the exhaust custom built at 2.25" (collector size) all the way back. I used two $35 cats from Dynomax and had to cross over to the passenger side with both pipes to avoid my second gas tank. After the cats the pipes go into a dual in/dual out Flowmaster 50 series muffler (cost about $95 bucks) and the custom aluminum pipes end up in 18" X 3" stainless pencil tips (about $80 bucks) exiting underneath the rear bumper. The pipes cost about $300, the headers were around $350, so all told it cost nearly $900 bucks for the exhaust.

I've installed a set of Hedmann "shorties" although for 4x4's, long tubes would be better for "scavenging effect" The "shorties" were easier to install with the "Y" pipe set up on my "95". (emmission control area, so true dual exhaust unless factory are not legal) We "modified" these for a 3in. custom bent exhaust system. My buddy runs a Midas shop. Just hope it passes smog check next year.
