Sorry but that doesn't make sense, SS would not double the price, just the material is changing, yes it's more costly but I'm sure most of the price is for the labor, which isn't changing.

Ok, it may take a tad longer to machine the flanges & also the welding rods may also cost a tad more, but...

lol i want to see these headers on a c63 with straight pipes @ second cats and resonator. I'm scared it'll be too loud lol. and i sold my cats already..

TheVazha

Lucky. In that case, I would get rid of primaries and keep secondaries. You shoudl pass smog and have the perfect amount of back pressure and that golden sound. One downside with the E63 is that it only has one set of cats and they are right up front after the headers. I think it would be a million times better to allow the motor to breath easy at the motor and then muffle/create back pressure towards the rear.. We'll see what the dyno says!

I'm not a metallurgist crazy1, just going with what my guy tells me!

I think this is the golden combo. Must have secondary cats tho. Or primary. Actually I don't think it matters as long as you have any cats in!

So.... will these fit a RHD if not what do we need to do to make them fit.... ?

Bigtickets

Did you get it on the dyno yet?? Whats the verdict?

TheVazha

Best I can do is give you pictures of them installed on my car. You can see how much room there is, and they would correspond with the same part number of the OEM manifolds. You know what the underneath of your RHD looks like, do you think they'll fit? Let me know!





Not yet, Jerry is out of the office today so can't get anything done. I'm waiting on a call back from EC in order to schedule dyno time..

I think no secondary cats and no resonator would be overkill, but with just one of those two out, I think it would sound phenomenal!

aussie e55

maybe compare part # of left & right hand manifolds

my bad should have typed
maybe compare part # of left & right hand DRIVE manifolds

That's the first video in this thread, no cats. It sounds tame in the vid but it's just WAAAYY TOO LOOUD. That's why I said I tip my hat to the guys running no cats and LT's. I just couldn't pull it off. I'm chasing a sound, not decibels!

Yeah that would be a starting point. I don't have them handy but these were built based on the OEM LHD manifolds. So if you're running the M156 LHD manifolds, these will fit.

johnny--2k

Well, I still have primary cats, just deleted the secondary's.

Any updates on this being available for purchase??

computertom

Any news on Dyno Numbers and purchase possibilities?

Thanks,

Hi Guys!

Sorry I have not had a chance to update the thread.

So, the headers are installed and they fit 100% that I already posted. I did a dyno pull WITHOUT the updated tune for the headers and I picked up a handful of HP and TQ.

Stock the car put down 421/380. With the EC V5 software and headers, stock cat's, the car put down 436/400. The header tune is sitting on my desktop waiting to be flashed. However, before I flash the header file, I want to sort out the Cat situation. The E63 has one set of extremely restrictive cats. I ordered some 300CPSI metallic cats and before I do the header tune and go back on the dyno, I will install those. You guys in the C's are lucky, you have two sets of cats so you can always eliminate the primaries and keep the secondaries. That's what I did in both my M113 motors and you get optimal flow, pass smog, and get amazing sound. On this W212 it's a PITA.

I anticipate, as well as my tuner and fabricator, that with good cat's and the header tune we shoudl be at 440HP-450HP and 415TQ-425TQ.

As far as the way the car drives with the headers, stock cats, and no tune, it's a beast. I'm coming from two modded SC AMG's and those pulled and pulled and pulled forever it seemed like. This car feels the same way now. It was the one set back to the M156, that it wasn't as powerful as the SC 113. With this set up however you get all the refinement of the motor/trans and the power of the SC cars.

I will keep you posted!

BLKROKT

So you're saying with the V5 tune AND your headers, your car picked up 15whp over a totally stock car w/ stock tune?

Um.... no offense, but that's kind of underwhelming isn't it? Are you sure your headers aren't making less hp than the stock manifolds? Something's not adding up.

Gerry_M

Not sure how much a V5 tune adds to an E63 already with the throttle already opening fully.

CaptnCharisma

Any info yet on if when we can order them?

TheVazha

None taken bud!

We did a dyno run with just the ECU tune and that was somewhere around 430/394. I don't have that graph but I know that we picked up about 5-6 hp/tq after the headers. The problem is that my car has a double stacked ceramic composite cat in one big basketball sized box. I hear from a very reputable tuner that on the W212 E63 the honeycomb is 1000spsi+. That's why I want to sort out the cat situation before I go any further.

Unfortunately not much. It does open the car up a bit. What's nice is that you pick up the majority of the power down low where this car is gutless in stock form. This is where you feel to too.

As soon as I get all the details sorted I will start a new thread. I need at least 7-8 people before my fabricator will agree to build them at the pricing that would work. I think there are 4-5 already interested but I will get a list going at some point.

TheVazha

I have two sets of cats in my possession!

I have 200 CPSI Kleemann cats as well as 300 CPSI SFX Performance cats. I will got to the shop tomorrow to R&D the best fit. After that, it's tune and dyno time!

In other news, the headers have been on my car for about a month and still all is well. The car sounds BEAST and pulls like crazy. I'm very excited to see what happens after cats and tune!

StanAE86

Still following...wondering if V-band clamps would be better...but watching and waiting! Woo woo!

TheVazha

HUGE UPDATE!

I finally solved the cat situation. After an afternoon of R&D, we are headers ----> 300 CPSI Viper cats ----> H pipe ----> 200 CPSI Kleemann cats ----> resonator ----> stock exhaust. The sound is amazing. Not too loud but still scream at WOT. I think we have optimal flow with reasonable loud. You C guys are spoiled with your primary and secondary cats.

Anyways, dyno scheduled for Monday morning. Also, we are calling the headers "CB Mids".

Wishing everyone a happy 4th!

TheVazha

Gents,

Unfortunately, I am unable to continue my project. Last dyno of the headers was with the stock cats. After I installed the high flow cats, I got pulled over and found out my license was suspended because of a ticket I got on a car I don't even own. The officer wrote me up for driving on a suspended but didn't tow my car which I guess was nice of him. I got the ticket dismissed and thrown out but it gave me a good kick in the ***.

The truth is I bought this car not because it's the fastest on the road but because it is so much more refined than my previous AMG's. I realized in the past week or two that I am no longer interested in chasing dyno numbers so I can sell headers. For my needs, the car is way too loud with even the high flow cats. I loved the way the car sounds stock. It sounded insane with the new set up but for me personally I think it didn't fit what I was going for. I have clients I have to drive around and it's not for a DD.

I have put my stock cats back on and kept the headers of course.
I have no stake in this and just genuinely wanted to bring something to the table for you guys looking for headers at a fair price. I have a kid on the way and I have decided to not spend any more time or money on trying to squeeze another handful of ponies so I can prove something. Even if I hit the 450hp mark, I'd still take it back to stock cats.

If anyone is interested in the headers, I can still get some. I hope someone out there picks up where I left off and posts some insane numbers.

CaptnCharisma

I'd love to be able to get some! Whenever you can post the info we'd appreciate it! Ballpark how much more power did you think you were getting after you installed the tune for the headers?

Badmeat

I came here, read this, and was disappointed. I'm hoping someone jumps in where you left off and gives us the climax we've been waiting for.
