Personally I like exposed welds. Nothing to hide in an exposed weld. Just like a race car chassis. ...no need to grind on something beautiful (unless it is a big titted hot skank)

this is the set I have on my jet boat. they are water injected as I have an open engine bay.

I paid less than $300 bucks so I figured I would try them. they are not perfect, one bolt hole in the flange is in the wrong place, had to grind the flange some for plug wire boot clearance, the flange is chrome steel and the chrome flakes, but for the money they dont leak and have held up well. considering a set of chrome Bassetts are over $1000 I feel pretty good about them. the welds all look pretty nice and for the money they have been great.

More importantly, what guage 321 stainless?

Seriously, what do you expect for $359?

My question is how dose it compair to a stock mercruiser manifold? Height, turn down angle, width, exhaust opening (O.D.) 4"? work with caption's call? Those would look nice on my 502 :)

Hopefully they call back. Must have wacky hours

Can someone explaine how can i do these headers fully dry ? Plesae

I didnt expect much for the price. they are pretty decent and have held up well. mine are single wall and only have water to them after about 1500 rpm but they have not had any issues so far. the welds are nice and I havent seen any cracks or other such issues. for the money I would use them again.

weld up the water dumps on the header,then you have to weld a water nipple on the collector,where the water is,closet to the end of the collector.usually just before the original water dumps.

these headers are most likely made in china,thats why there so cheap.granted,the stuff made there is getting better.the cx racing turboes seem to hold up,,for a while.

I'm usually the first to jump on the whole US made band wagons but when it comes to some things it's just crazy what they charge. I can say for the money I'd extend the tails a little and run em. I think they would be a decent upgrade for a 502 mag or something like that.

My brother has a jet boat with an enclosed engine compartment...I am not familiar with jet boats but would these be suitable for use in an engine compartment?

No ,not the water injected ones ...Your brother needs water jacketed

he can use the double wall headers

I knew I saw these guys some where before. In the Toyota Supra community witch I came from they were know for junk manifolds and turbos. In the passed you can't get a hold of anyone, shipping times could be 3 days, other times 3 months. Missing parts in "kits", metal shavings in intercooler,s shabby welds, misalignment issues, ect.

Got to be a member to see the photos, http://www.supramania.com/forums/sho...her-names-used
But pretty much showing the bad feedback and othe rpeople getting ripped off.

I found " some one" else posting in the world, about these out there. Now if they just came out, and there trying to get the word out, or what. Photos a guy posted on another site "decided to give XS-Powers Doubled Walled BB Headers a try and here are some pictures" "look at what I jsut bought", bla, bla bla, are the same photos on XS site........

Another site they go/went by , http://www.ssautochrome.com/level.itml/icOid/2150

https://www.google.com/#q=817+beaver...dmoor+nc+27522 Their address just typed in to google.....

Just a FYI. Google them. Also knowen as SS auto chrome.
Maybe quality has gotten better since then but I dont know... Untill a reputable member puts down the cash, with a real review on them, I'll let some else take the chance.

As I said on page one, sounds too good to be true. :lolhit:

As I mentioned I already talked to these guys plus emailed back & forth over a month ago. They wanted to get the word out about their headers. They were going to send me a pair but as of today I never heard back from them. I was going to test them first on a dyno to see what numbers #'s and if any durability issues showed up right out of the gate.

I told them that would be great marketing for them if their header produced +'s all the way around. Also said their customer who posted on performanceboats.com was not going to sent the world on fire with sales for them. They needed to be proven first before anything else especially being a newbe on the block and especially being on the auto & import side of the coin...

:whistle:

But yes, I am very interested in your findings once you get them. My experience with them was over 3 years ago. A good alternative to $3,500 headers would be nice

Finally got ahold of them. Couldn't answer even how wide they were. Tried calling back a million times, no answer, no return call, nothing. I even wanted to just order two sets on the phone when i was talking to him and he told me to look at the other forum thread first to see the pictures that were the same as their site. I'm walking away. Someone else can get swindled by this shady outfit

Businesses cost $$$$ to run.

A person doing side jobs is much cheaper.

in a free courty every one says what he wants, but the decision is simple . or you buy these XS headers for $1470 shipped worldwide or you pay $3500-$5000 for a set of branded headers .
also you can buy a secound hand USED branded headers for $2000 if you want. i personaly decided to try the XS headers for $1470 shipped there was NO comparison in price.

These chuckle heads obviously do not realize the potential market for these. Their advertising sucks and the spamming wrecks credability. These guys seem clueless when it comes to running a business.

As for the cheap "buy in" price........
Well, how does the old saying go?

"You can pay me now or you can pay me later". Later will be exponentially more expensive!

Yes, but alot of guys have went the expensive route(CMI) and it was no better......

so do you have them?when did you order them?

thats why stainless marine exhaust is so nice,,it eliminates problems and it doesn't rob you of power.

That's what she said.. or what your engine said :)

Let's see pay $5000.00 a motor for cmi big tube or e tops $3000 a motor. They will crack in 3 years and you will have to pay to replace them again or by xs power for 1/2 the price? And personally i think the welds would make them a little more more forgiving with less chance of cracking. Fixing i am sure would be half the price. Of the inner pipe is more than likely one piece and the only difference is the outer pipe. Don't get me wrong cmi is a great product but way over priced because they are the only ones who made a water jacketed header.

And you know the CMI will crack in 3 years? Because I know of many CMI 10 year plus with no issues.

The company is already known to have issues with car headers, and now you are going to trust your engines to his water cooled design? My engines are worth more to me then a gamble to save a few bucks.

If you can't afford a big name, well built, proven marine header then choose some of the after market manifold and cast aluminum header designs to save money.

While I do agree that its tough to argue how much engines are worth someone does need to step up and give CMI a run for the money and make the price go down.

Since these clowns still haven't called back, maybe you can answer my question since you bought a set. How wide are they?

I learned a lot about headers during my build. When you buy production made headers that's exactly what you get. on fountains side by side application the tubes have an 1/8 inch between the motors them making it near impossible to change spark plugs, and to take the valve cover off which means you then have to pull the header. Just a headache all around. However when you purchase headers from those whom are the best in the business things turn out to be the best. when I put my big tube dry Stellings on after Randy worked his magic for my application things couldn't have turned out better. Just a real work of art. 4 inches between the pipes with plenty of room to pull the valve covers off. As previously mentioned, if you cant get your hands on a good set of headers from those who have been in the business for quite some time I would purchase a quality performance manifold and stay clear of the headaches that come hand in hand with "off the shelf" headers.

That's just the 32, plenty of room with cmi side by side 35,38,42

I found this in National Dragster.

Yes that's true, the 32 and 29 twin are built tighter than a shoe horn ha

Are you guys ****ting me, these look like a kindergartner built them!!! These guys built a bunch of turbo manifolds for jap cars that quickly fell apart, you get what you pay for. Just buy stainless marine gen 3's if you want durability, Smitty

in the welding world,,we call them welds a bunch of grapes,,done by the Gallo brothers.

Procomp, Ebay, and Walmart business model. Works for those three apparently.

Thats unreal....., especially with stainless.... The first time I tiged stainless I was in awe at how nicely it welds compared to crap mild steel dom. That looks like a stoned kid in high school metal shop did it.

Well I bought 2 sets here are the pics, they don't look nothing like that crap picture above[ATTACH=CONFIG]538895[/ATTACH][ATTACH=CONFIG]538896[/ATTACH][ATTACH=CONFIG]538897[/ATTACH][ATTACH=CONFIG]538898[/ATTACH][ATTACH=CONFIG]538899[/ATTACH][ATTACH=CONFIG]538900[/ATTACH]

I don't work for the company but I called him 4 times in one day and had no issues, they are jacketed not injected
