New SS Long Tube Headers being made for CLK63BS.
Just before my yearly trip to the PRI Show I reached out to a respected MBForum Vendor for headers, but the added cost to enclose ship my car back & forth from NJ, was troubling.
Merry Xmas... at PRI I found a local header manufacture that agreed to make an SS Long Tube with 4 into 1 High Velocity Merge Collector with joined Mid Section.
The System will be a complete bolt on... to the rear AMG mufflers.
My CLK63BS is there now.
I'm also planning on having them Ceramic Coated at Swain Tech to lower the under hood temps.
I'll post photo's when I get some.

headers
I understand from speaking with Jack Burns that the "tri-Y" long tube headers increase power over a wider RPM range. Either way, have the company make a fixture so they can duplicate the headers.

They have made headers for C63's already.

4:1 vs. tri-y debate has gone on for years and there is no clear winner.
For these cars, Cart uses try-y and i use 4:1 and we are within 5 horse of each other and being we are both over 660, the difference is nothing.

What size diameter are the primary tubes on your 4 into 1's, most are 1 7/8".

Let us know how they turn out Jim. You can't go wrong with any LT design, this motor responds very well to LT's with either the tri-y or 4 into 1, win win either way. Please post some pics when you get the car back.

Somewhat off topic, but for those of us living in emissions testing states that need to retain their cats, does a "shorty" design add any significant power increase over the stock manifolds? I know there were some renntech replacements discussed here some time ago but don't recall whether there was any real world analysis of their performance characteristics.

Does your state do a physical inspection or just plug you into and OBD port reader? Most states have switched to and OBD only inspection and if you do not have any CELs displayed and your O2 sensors are working you will pass the emissions test with flying colors. Even if an inspector wanted to do a physical inspection, one peek under my car and they would see my resonators which look like small cats. Even if they plugged me into the tail pipe exhaust readers I would pass becuase my catless car in a good state of tune burning quality gasoline(race fuel in my case) will fair better than 75% of the cars on the road with cats in place running cheap gasoline and a car that has not has a tune up in 80K miles. I just had my E46 M3 pass an IL emissions test with primary cats deleted, passed with flying colors.

On another note...
I was talking to the Header Company today about stepped vs. non stepped headers and the HP differences.
They explaned that on race cars running with open headers, steps are best & expensive.
Street cars with full exhaust would only gain 3 to 5 hp with stepped vs. the non-stepped, reasonable headers.
Reason... the extra pipe after the header is the equalizer.
They have averaged +40 RWHP with just their C63 header.
On my NJ car we are using metalist cats at the front of the mid pipes.
When they send me progress photos, I'll share them with everybody here.

I don't understand why a stepped header would be so much more expensive. If they are fabricated by welding curved sections of stainless tube together, the only extra cost would be that of the slightly larger tubing. As a benifit, of the stepped design, you get a slip fit joint rather then a butt joint at the steps.
The Header Company has some really neat machines to shape things.
Their header tubes are one continuously formed pipe thats only welded at the flange and the collector ends.

Interesting. CT has closed its state inspection stations and subcontracted out the jobs to local gas stations. All these guys do is plug the car into the OBD reader. This thread has suddenly become much more interesting as NJ isnt that far away. However, don't you need an ECU tune anyway to take full advantage of the headers and don't those modifications turn off the O2 sensors to prevent the CEL display?

Ya, ever since Rod Blagojevcih went up the river Illinois isn't the same
Headers+ cats in California= fail. I've appealed my porsche twice and they just smile and say it's the law, we don't want to hurt the whales.

What these guys do is cut apart the prototype header and take the degree and rotation, then they bend each pipe to make continious primary tubes.
Passenger side is done and I believe they are making the Fixture, then the set will be done.

They figure the finished headers may be ready to send to the coater on Monday...
The difference between Swaintech Ceramic coating and typical header heat coating is vast.
Car had a healthy sound to it before, I can only imagine after this...

The headers will come back from Swain Tech with a white ceramic finish.
It's the same Hi-Tech finish you'd see on race cars at the 24hrs of Daytona.
I've asked the header shop to secure 2 cans of VHT Flameproof silver and spray them.
Not so much for additional heat coating but more for looks..
Has anybody else... noticed how different this set of headers are..?
