Cobra Manifolds...again..

[CanadaMarauder]

Sorry I couln't find a thread saying wether the cobra manifolds bolt directly onto our cars or not....I'm taking the rear cats out this season and will have the pipes off anyways...if the cobra manifolds will bolt up at both ends I may concider doing it all at the same time.
Thanx

[fastblackmerc]

Yes they do.

[ImpalaSlayer]

whats the advantage of the cobra manifolds? why not after market?

[Black Terror]

Yes they do.

I don't believe Cobra Manifolds will hook up to Marauder Exhaust Pipes.

They flow better than our stockers that are shaped like lincoln-logs. They also enable you to bolt up an aftermarket X or H pipe because our stock manifolds are not compatable with aftermarket Mustang Midpipes.

[Blackmobile]

I have to agree. They will bolt onto the heads but not the MM OEM exhaust. You would then need a cobra X pipe. One manifold is flanged and the other is custom.

[CanadaMarauder]

Thanx all..just though if they gave acouple extra horse and could get a used set for like 100 buck then it would be worth it...

You could probably get a set for even less than that. Once you get them you will have to alter the driver's side manifold to accept the hook up for the Exhaust Gas Recirculation system (EGR). That could be tricky.

[Dennis Reinhart]

Yes they do.


Sorry they will not bolt to the H pipe, that's why there sold with the new x pipe.

[safado]

Question for clarification...They wont fit the Marauder H pipe but they will a Terminator H pipe? And will the Terminator H pipe fit the underside of the Marauder? What about having to shim the motor mount?

[Vortech347]

The Stang mid pipes have to be extended 3-4 inches I think.

[Blackmobile]

What about having to shim the motor mount?

That's not a problem with manifolds, they just bolt right on.

[Raudermaster]

Not sure about the Termi H pipe since all the people who have the Cobra kit (myself included) keep the X pipe. I'm sure Dennis could say if it would fit or not.

[KillJoy]

I have a set of Cobra Manifolds sitting in my Garage.

Best offer. Shipping MAY be $$$ due to their weight though.

KillJoy

PS - They mount to the Heads fine. You will need to "adapt" the EGR Tube to fit, and get a Cobra X or H pipe, and extended it 3-4 inches to attatch to the stock muffler pipes.

I have a set also to sell and will bet any price Killjoy offers.:):censor:

Clear!!!!! bringing this thread back to life...... What gains have been seen by switching to the Cobra mani's? Or for that matter getting rid of the 2 inch exhaust? Dennis's cobra manifolds are Ported or just out the ford box? From what I gather the kooks system averages about a 25 Hp gain.. but at 2K for the system is it worth it?

There not out of the box, there cleaned up and jet coated, with a twin highflow cat and X pipe, and for the cost difference I would go with Kooks but I will help any way I can, the cobra kit is easier to install than kooks.

Dr Cobra manifold setup is fine by me. They've helped get me to the #2 (NA) spot on the timeslip page, but the ones on my tail are sporting SS headers. One point of interest for me was headers need their bolts to be checked for tightness periodically, where as manifolds once tightened, they are done, you can check um, but you won't be tightening any of um. But if you want go with headers, get um ceramic coated, you'll thank yourself later.

If the Cobra Manifolds are available as take offs, can we get the H pipe seperate?

You mean X pipe because that's what attached to the Cobra manifolds, and on the X pipe are the 2 High flow cats which completes the set.

You'd be able to get any aftermarket or even stock 99-04 mustang mid pipe..

[Bradley G]

any difference in diameter than the stock pipes?

Which begs the question............ why are they being taken off?

[MarauderBoy]

Adding to the mix of those with available ceramic coated DR Cobra manifolds for sale

Because its their next step in power.. the long tubes do give you more power.period.. but is the 40 horse power worth 2K (complete exhaust)?

For the budgeted/ not looking for max power.. you can get some cobra manifolds for 25-60 bux a mustang no cat x-h pipe for 100.. and some muffler shop work for less than 500..

Our cars have studs, not bolts. The nuts have not loosened up at all for me, and I don't recall anyone else complaining about the nuts loosening on their Marauders. Concerning the ceramic coating, the headers sold for our cars are stainless steel and the only potential benefit is a reduction in heat transfer.

[Bradley G]

The idea of changing exhaust concerns me due to NVH.
I like the way the Marauder sounds stock.
I've only heard a few modified (exhaust)Marauders that I would consider to be my taste.
Being that the Cobra Manifolds won't transfer as much sound.

Try putting a wrench to your header bolts and see if you can tighten then up just a little more and you'll notice they will turn. Uncoated headers and manifolds will change colors due to the heat. Ceramic coating makes them LOOK PRETTY, and they will stay that way.

I agree, the tone goes downhill once people start putting flowmasters and the like on the car. I doubt changing from one set of manifolds to another will make any noticeable difference sound though.

[safado]

Ya the stock mustang H is 2/14 and the aftermarket H-X s are 2 1/4, 2 1/2 or even 3 inch

The big flaw I see with the marauder is the 2 inch after the rear cat... garbage (for Power) look at the Auto MACH 1 (basically a "small" Marauder)
its 2 1/4 all the way thru..

[red]

We have studs, not bolts. See my picture below. You need to retighten (regardless of fastener type and manifold/header) due to gasket compression. Ensuring that you're tightening in the correct pattern will help avoid leaks with headers AND manifolds. Also, studs only require a hand-tight install and are by design better suited (and recommend) because they allow for even torquing. One should NEVER overtighten a stud or bolt. Read ARP's FAQ (http://www.arp-bolts.com/FAQ/FAQ.html).

I disagree that a ceramic coating will "stay that way". Even Jet-Hot only warranties their ceramic coat for 3 years. With the more expensive coatings, you can spend as much as the headers cost. Are the aesthetics worth it? Even DR states that the coating is unneccessary:

there is no real need for ceramic coating there all stainless steel

What year Cobra are the manifolds from?

Any one have a pic with Cobra manifolds (w/ EGR mod) and cat delete midpipe?

My advise for what it is worth is decide where your end game is and mod to that end. Baby steps are expensive. It only cost me a couple of hundred dollars more than my crappy Cobra exhaust and sloppy install to buy, ceramic coat and have installed Stainless Works Long Tube Headers with custom H pipe. The $ spend on the Cobra stuff was wasted money. Little or no performance improvment and an exhaust that dragged on the speed bumps to boot. The high pitched tone from the X pipe didn't please me. There is a reason why all of the Cobra guys are removing Cobra exhausts, doncha think? Dennis

OK Dennis, we can retract our claws now. :D As for the performance difference over stock, BIG difference if you are ever at WOT, and I'm there a few times a day. As for the difference between Cobra manifolds and headers, thats a personal preference, Mind you, I got to the NA #2 spot on the timeslip page beating out many header owner on the way. The Cobra manifold and X pipe setup isn't perfect, but everything on these machines are custom anyway.

[Stranger in the Black Sedan]

Some people, myself included, just don't want headers on a luxury car. I have headers on my old cars but would not want to drive a big quiet car w/ them. Headers transmit a lot more tinny exhaust sound to the passenger compartment, and even really expensive headers often end up warping and leaking after taking them on/off a bunch of times. The cobra manifold will no doubt be an et improvement vs the logs, tested back to back. For people like myself who weld, making them fit and have good pipe clearance shouldn't be a problem.

No thanks.
