The header/exhaust project is moving right along. As I was leaving the shop the header flanges are all water jetted out and ready to go. So tomorrow its time to hit these headers full tilt. I'm about 3 days out from header completion and and other 2-3 day for the full on exhaust system.

As I was leaving I couldn't help but to snap this picture of a trophy truck header set that was being finished up. My friends work is insane to say the least. also some other pics of his work.

 

looks sick mike! can't wait to hear these new headers on your car. im stoked....

but bars fri and pavillions sat maybe? lol

 

Bar friday night??? I'm down. As long as you can hang all night and not skip out or pass out for that matter.

 

haha.....

and when these ballin' headers come out and your full exhaust, we're going to need to get some drive-by and outside car while driving clips. can't wait to hear these things. they're going to be the real deal!

 

Are your headers going to be true equal length? Those pics of the other headers look pretty good.

 

Dont get me anymore excited than I am. I hope people like them when they hit the market. We are making removable cats for the headers and they can be replaced with "test pips" at your leisure. Did you get those gaskets?

Here is a brake down of how the system is going to work. Long tubes then a removable cat with test pipe replacement. (so you can be catless or catted). Then to xpipe of some sort back to dual strait though mufflers. These headers should be able to fit on the stock system with minor mods. You can get the adapter flange welded into the stock setup and and then hang the headers and cats and have a long tube header and stock pipes if you so choose.

 

Looks very nice. How much? Are these going to go from the heads to the mufflers?

 

no not yet. i thought you were gonna call up that guy you know over at the dealership to hook me up lol. call me later.

 

I know these headers will be fabbed up using the firing order of the engine along with specs from the engine using computer aid software.

 

I will do that tomorrow

 

Looks good glad everything is coming along I never heard of removable cats, but it's a good idea for those who can't pass smog. Oh yea today I saw a M6 with the plates AMG TKO lol made me think of your story again.

 

This is just a pic off of goolge of a test pipe and a cat side by side. Just to give you an idea of what I'm talking about.

 

looks good a lot more practical then having them welded off and on which was my plan if I had smog issues.

Man these servers are really jacked I wonder why they don't have double post protection on here (old technology)

 

wow that pic is huge sorry.

 

on hooleyboy's friend's welding..!!!!

 

on hooleyboy's friend's welding..!!!! FREAKIN AWSOME WELDING...!!!!

 

My buddy is a true artist when it comes to welding and fabrication. The stuff he can make just might take the AMG to the next level, And I'm more than happy to have him on board with MBH/Dyno-Comp. There is no doubt in my mind we will get a whole bunch of world class products available to you guys with in-house dyno proven results at a fair price.

 

here is a quick pic of the passenger side. Car should be finished Wedsenday or Thursday. Then its on to Dyno testing and road testing.

 

Mike any idea of what they are going to cost?

 

I going to sit down with my fabricator and go over numbers this week. At this point i'm paying for all the jig, watter jetting setup costs and stuff out of my own pocket. My cost for my set will be much high than what they will cost on a reproduction level. I fear tossing out a number right now, as it could be more or less than any of my estimations. I will for sure have a number this week.

After testing for about a week... I plan on making them available ASAP. I dont have the best C55 in the world to test on but I know my last exhaust system and headers made 20whp. I'm going to have him fit this system to a stock C55 exhaust and see what happens.

Other important things to note is.. These headers are designed off of the C55's engine specs like compression ratio, bore, stroke, valve size, cam specs, throttle body size and so on. Also some headers available for the C55 do nothing but fit. We were looking at all the header options for the C55 and found that a few of them did not follow the firing order in the collector. The firing order should fire on a clockwise or counter-clockwise order pending on how you look at it. In turn increasing the scavenging capabilities of the headers or in other words how much the headers actually suck out the exhaust gases under a created vacuum, rather than just pushing the exhaust out of the cylinder head.

With this info being brought to my attention, it just backed up what I had already known. Most headers for the C55 were made for other cars and do not follow the firing order of the C55. IMO not following the firing order will leave power on the table. So this will truly be the first collector style header available for the C55 that follows the C55 firing order, not to mention the first long tube header available for the C55 as well.

 

Thanks Bro!

 

thats sick mike! can't wait to see and hear these!

 

Kudos to you for making affordable mods for the C55 guys. All in a record time frame.

I'm interested to see what you are going to do after headers/cats.

 

Maybe not, I know around here at least, shops are very reluctant to do any removal of emissions equipment on street cars. I used to work at a speed shop, and the shop that we sent our installs to could get in trouble for installing catless H pipes.

I don't knwo the rules with secondary cats, or any other state for that matter, but dont be surprised if they say no.

What you could get away with is asking them to cut your cats out and weld on flanges. Then just bolt them back in, weld some flanges onto some pipes for test pipes, and hand them to you. That way the car still leaves their shop emissions compliant, and you just go home and bolt on the test pipes.
