Nice looking product...these are shorty headers, correct?

LZH

Also - would they fit a CLK Black Series ?

_AMG_

Great looking headers. Those look like some heavy duty flanges.

SphereMotors

Actually this is long tube short header.

SphereMotors

Yes, it would fit perfectly!

aussie e55

would they fit a L/H drive C55 thanks

superlubricity

Sphere, those are definitely shorty 4-into-1 headers. They certainly are not long-tubes.

It also looks like they require cutting/welding of the factory down-pipes/primary cats. The OEM flange on the top of the factory down-pipe is only two-bolt.

Can you clarify?

SphereMotors

This particular header is for 63 only. We do offer for 55 but not in stock at this time. We estimate about 3 weeks. Once it is out we will post it.

SphereMotors

You are correct regarding 4 into 1 pipe and yes this is not full long pipe type header such as MBH. However, this is not short header like 1 pipe with 4 holes. I might of used politically incorrect wording but I just wanted to everyone know that it is not short type such as 1 pipe with 4 holes. I apologize if I might have confused you in any way.

Regarding the flange, yes it does require welding but it comes with the flange so you can bolt on installation. Here is a pic for reference:




Let me know if you need more info.

_AMG_

Any sound clips or videos of the headers?

sflgator

Nice looking headers, but it's difficult to imagine that anything other than "long tube" headers could yield net gains of your suggested 48 RWHP / 39 RWTQ...any other dynos done other than that one?

Sincity

Welcoming more new performance products for the C63. Noticed the tune is by Techtec. By any chance this is the same tune as MHP? Do you have any under carriage pics of the header installed. I am just trying to imagine how they weld onto the stock DPs.

Sincity

Aren't the "4 holes to 1 pipe" simply called "exhaust manifolds" like, OEM, Kleemann, and PLM?

RStevens63

Not possible and I'm glad you saw it as well. No shorty will yield gains even remotely on par with any LT. 482rw with a shorty header haha!


Those are called exhaust manifolds or logs. Your product is a true shorty header.

c32AMG-DTM

As others have mentioned, "one pipe four holes" aren't headers at all... they're exhaust manifolds (some aftermarket vendors choose to call their versions "high-flow exhaust manifolds" - but manifolds nonetheless). There is no such thing as a "long tube short header" - in essence, that statement and phrasing doesn't make any sense.

FWIW, I don't quite get the logic of a "bolt-on installation" of the header, when you have to cut/weld the stock pipe to add the flange that accepts the headers....?

Most prospective clients (IMHO) consider "bolt-on" to be hardware that gets bolted into place without any cutting or welding, and is 100% reversible if they wish to remove the items and bolt the stock parts back in place instead.

Best of luck with your venture.

I was in the area today (on the way to a train store in Anaheim) at 10 am and called a couple of times so I can see them for myself but no one answered the phone. I guess you guys aren't open on Saturday?

wawy

Thanks for posting. I'm sure some of the C55/CLK55/SLK55 guys would be interested if you're making some..

fourAAAA

I think kleemann use "headers" on their products.

This product looks similar to kleemann headers for 55 engine.

So...Kleemann, are they also using wrong word?

I think I have to ask to kory cause I installed kleemann headers on my slk55.

Hey sphere do you drive slk55? Did you install your headers on it?

fourAAAA

Hmm...so you are saying kleemann headers is kleemann exhaust manifolds not kleemann headers.

However why kleemann calls it headers.

Me and some of slk55 owner already installed kleemann headers on slk55 forum, we called it kleemann longtube headers.

Anyway I dont want to care how to call it but I can understand what it is for and where it should be used.

SonnyakaPig

Sphere Motors, if you don't mind me asking, what are the SAE numbers on this Dynojet for stock, tune, and tune+headers?

Have you tested the headers on the motor with the stock tune? If so, what were the results, including AFR?

C63fan

+1!

c32AMG-DTM

Yes, they do.

Agree.

With their 63 product, I would say yes. With their 55 product(s), I'd say no - they're headers.

SLK55 is a cool little car - it would be interesting to know of any products/results for that vehicle as well (in the appropriate subforum).

Mort

The Kleemann exhaust headers would be referred to here (NA) as log style manifolds. They are essentially the same as stock manifolds with very slight improvements and perhaps a 0-15 hp advantage. They will maintain very similar driving and power characteristics to stock exhaust manifolds.

Next step up are short-tube headers as in this thread. After that are mid-length headers and then long-tube headers.

It depends on your goals and how much compromise you are willing to accept, in terms of HP and Drive-ability, which you should choose. Long-tube headers will generally give the maximum HP increase at the cost of low rpm torque and loudness.

SphereMotors

This header is by Techtec Korea. Since I don't know about MHP, can say much about that. As you know it's hard to take picture once it is installed. We'll try to take a pic and post it soon.
