You can, but odds are one of the mufflers are going to be in a danger bashing zone. Cross over keeps the exhaust up where it won't get bashed on rocks.
My cruiser had dual exhaust with ram horns, but it was the most crackhead job I've ever seen.

I just got a set of 2" ram horns from 1aauto for $49 each plus $18 each delivery. Received them in about 4 days UPS. Center dumps.
They are very heavy and stout - and look very well made. Much better than the headers the p/o used - they glowed red and became almost see-through (not to mention the butcher job on the inner fenderwells).
Is it worth it to have them coated? I have a 400 sbc, and am concerned about overheating.
Also, can I buy the NAPA crossover mentioned above and bolt that sucker right on, or should I have someone fab a crossover and the rest? I'm on an extreme budget with my new (to me) cruiser and am trying to get ready for GSMTR, so any advice would be greatly appreciated.

Ramshorn's in a junkyard?
Yea, right. Maybe 15 years ago.

I'm not trying to turn this into chat but they are out there if one will look. The ones that used to be in the junkyards are now on EBay or being hoarded away like my 3 spare sets.
I guess it's like anything else...deals can be had if you are not in a hurry and are willing to look around. Remove either factor and the price goes up exponentially.
The AI link looks like a good deal if you want new or don't want to scrounge around Ebay.

2.5 inch is a corvette application
2.0 inch is everything else.
The walker corss-over pipe that people are talking about fits only the 2.0 inch manifold, and you need to source a heat-riser block off (or use it). These manifolds are cheap cheap
The sbc likes headers with like a 30 inch run before the collector. The block huggers don't have anywhere near that run. I can tell you from experience that the over-the-steering, outside-the-frame-rails headers radiate A LOT of heat in the engine compartment.
The 2.0 rams horn manifolds have A LOT of positives.....
directauto sells new ramshorns for about 80 bucks per. Check your local muffler shop, they may have a pile swapped out for header jobs

Is this going to be trouble
Hi,
I don't mean to hi-jack this thread but have a question about rams horns.
I have a worn out old 400 SBC engine (1972 block) and I bought a new 350 SBC to replace it.
The new engine has a block used from 1986 to 1994 with the heads having center bolt valve covers, can I use the rams horns off the old engine or is this going to be a problem?

Just picked up my ramhorns at the junkyard a month ago. They still had another set or two. $30. Just cleaned em up, painted and worked well with the walker pipe.
Oh yeah and another thing I didn't see mentioned...or others have and I didn't pay attention. The studs aren't long enough on some models of ramhorns. I had to attempt to remove some...what a SERIOUS pain. There is about a .5" or greater difference that really about ruined my fun for the day. ;p

I am unsure but am inclined to believe they will not. You are going to need a different clutch, flywheel and starter too.

Like they said, not gonna fit.
Why are dead set your 400 being worn out??
If your 400 is built properly it will not overheat. People have overheating problems when they assemble 400s wrong. 400 heads have steam holes in them, people end up putting heads that don't have steam holes (say off a 350) and then they have problems.
Anyways getting your ramhorns coated is not going to keep the 400 from overheating. My best advice is get over the paranoia of an overheating 400 and enjoy the best SBC ever made.
In case anyone doesn't know about the steam holes, the cylinders in a 400 are siamesed - there is no water flow between them. The water can become stagnant around the tops end of the cylinders where they meet. The steam holes allow any steam buildup to escape into the head. If you use heads without steam holes, it blocks the escape of the steam. This creates hot spots that eventually can superheat the water around them, and at the same time the steam increases the pressure of the system. If it increases beyond the limit of the radiator cap, the pressure is released, but, this also drops the boiling point of the water, increasing the odds of a boilover.
This should not be construed to mean there is anything wrong wit 400's. They just have to be built right.

can't you use the RH manifold for either side if you don't need the extended bracket that some of the maniolds come with. The engine I plan to use does not have any brackets that connect to the exhaust manifold. I'm refering to the center dump "rams horn" type exhaust manifold.
I'm not really concerned about the engine overheading - have that under control - but with the funky headers on it now it is really hot under the hood. The coating question was centered around getting the heat out of the engine compartment. Thanks though.
What is a heat-riser block off, what does it do, and where can I find one?

i use two pass. side 2" ramshorns. these have the long studs and heat risers which i gutted. 25$ each at a swap meet ,plus 50$ for the 4287 walker crossover from summit i think. high temp paint, gaskets and good to go. jim

If you have the headers, you don't need the spacer. It looks like this:
http://www.corvetteparts.com/details/iid/13213201.htm
You can put a ceramic coating on the headers. When I had my exhuast re-done, the muffler guy said he was doing the ceramic coatingon the *inside* of the tubes. He said you could grab the headers with you bare hands and not get burned......
Rams Horn manifolds
I finally got my set off eBay. They are the Asian version, but still cost me $150 plus the ride. Corvette rams horns are at least double that. I didn't care cause I'm not building a Corvette. I just wanted functionality and headers wont fit my application. I'm talking about the 2.5". A 2.0" will work great with a 350, but I've got a stroker and my engine guy said "putting 2.0" on this engine is like taking a ham sandwich to a banquet. I wanted a torquer but he told me it is going to make the torque it makes and there is no need to choke it off. So I guess I get the horse power as well as the torque. I would like to know more about the coatings though. It is my understanding that the more heat you keep in the system the better it works.

The same guy must've converted both of our cruisers...
That's right... let's run the exhaust pipe right through the front spring.
And yes, this is dual exhaust... with rams horns.
