New Shorty Header Available

This is just an FYI if anyone is looking for a set of Shorty headers.

Pertronics/Patriot Exhaust has just completed a Shorty header design. These are designed to replace the stock free flow exhaust manifolds that are found on 70's ara full size Jeeps with V8's and on some AMC cars.

These are pretty much exactly like the Edelbrock shorty headers that have been discontinued for several years now. They are a direct bolt on replacement for free flows meaning no modifications to the stock downpipes. These are NON AIR headers!

These are available at Summit Racing, Jegs, Etc. part #H8600 for raw un-coated, or H8600-1 for the ceramic coated version.

Thanks
Dennis

These are brand new!! They won't be on anyone's website yet !!!

You will need to make a phone call LOL.
Give them the part number that I posted. Then they will probably have to call to get you pricing because they are brand new!!!!!!!

Why did Edelbrock discontinue theirs?

Because they offered no real performance over the stock manifolds on a smogged, street legal engine?

Or because no one was buying them because there have been a few threads here that say they don't offer significant performance increase for the price?

LOL, It's a shorty header, what do you expect! Anyone that understands how headers work knows that you won't see any "significant" gains with a shorty header. That was never the intent of the shorty header. They do in fact out perform the OE Free Flow exhaust manifolds that they replace(as has been seen in several dyno tests) but did not perform as well as a long tube header on the same engine.

To answer your question, Edelbrock has not been in the exhaust business for 3 1/2 - 4 years now! The Edelbrock shorty headers for AMC's/Jeeps sold very well !! Even today people are still looking for them on the forums. Pertronics saw the high demand for a shorty header and they decided to build them.

X2 to what Banchee said. I did back to back testing between stock manifolds and Edelbrock headers. Measurable increases all the way across the board. I'd have to dig it up again but very worthwhile gains. Not as much as with a long tube header, although I suspect the gains may be due to better collector design as opposed to simply tube length.

Banchee, what do the collectors look like?

I'm interested, when I get around to swapping engines in my GW I'd like to go with shorty headers, it should make things much easier than full length headers. What size will the collectors be?

Being a direct bolt on replacement the collector size is the same as the OE Free Flow manifold.

I was having trouble posting the picture that I have of the new headers so I emailed it to another forum member who was nice enough to agree to post it for all to see.

Should be up now!

... And they cracked where the flanges came together unless you put more supports in your exhaust system.

I'm sure they did, as any brand of tubular header would if the rest of the exhaust system is not properly supported. I've seen/fixed that mistake hundreds of times. Headers are not as durable as a cast iron manifold.

My plan is to make my own Y-pipe arrangement and use flexible exhaust joints. Even though the Y-pipe will be hanging from the transmission bracket like it should be, so that it moves along with the engine, this will ensure there are no stresses in the pipes, and it will also make installation easier since there's some flex to the pipes.

There ya go! Sounds like a good plan!

The OE style donut gasket on the collector of the shorty headers allows for a bit of misalignment as well as flexability, which will also help make the installation easier and will further reduce stress on the collectors of the headers.

the dual exhaust on my j20 has one hanger for each pipe,back behind the muffler. the hookers don't mind a bit. 25K+ miles that way.

So 25K miles is supposed to be good or something??

I had a set of Doug Thorleys on my 77 J20 tow rig for well over 50-60K miles (the exhaust system was properly supported) and I never had any problems. I also know people who have logged over 50K on there Jeeps (some rock crawlers) running the Edelbrock shorty headers that have had no problems either, so what's your point?

The last (and I mean last) set of Hooker headers I bought I couldn't even get bolted to the engine because one of the primary tubes hit the right side inner wheel well sheet metal. Yeah, real quality stuff!!!!
Keep knitting!

my point is i didn't have to add supports to my exhaust,due to my hooker (any brand) headers. i have fewer supports.

my hedman equipped vehicles are't exactly overladen with hangers either.

didn't mean to get yer underwear knotted up......you work for edelbrock or something?
