After many talks and meetings, I was able to renegotiate the selling price of the C55 long tubes. I did not feel comfortable offering the headers for sale for $3490.00. I was always pushing for the lowest price possible. In fact pushing for a lower price on these headers has some what set back other project. In the end I stuck deals to get the price of the headers even lower.

Pricing on the C55 long tubes will be set a $2900!!!

IMO these headers are very much worth the original asking price, but having to ask that much truly went against my reasons for becoming a sponsor.

lowering the price? wow....what a smokin' deal

hooleyboy

Yep, As I'm sure you know. Ive been pushing for a lower price since day one. It was only the other day I made some head way on the matter.

You should get someone to dyno them on a stock c55 or otherwise na back to back against the Kleemanns. That would be interesting. Still too high though as Kleemann headers and ECU can be had for 1500 and 7k for a Kleemann blower.

BTW R&D costs are usually expensed not incorporated into the $$

about a year ago I bought EVOsport headers for $2500, at that time Kleemann headers were $3500+. Renntech headers are in the $4k area. So i'm thinking a long tube header made with 100% US stainless steel, (321 and 304.) Made hear in the USA is a very very fair price at $2900.

I've gone to bat on the price of these headers. Almost to the point that I wanted to pull the plug on the whole deal because i was upset over pricing.

I find my car worthy of the best, and there are a few things about my car that are not that great, and i will be changing. One thing is for sure its not my headers.

I would gladly put my headers up against any maker of headers for our cars.

You might find, that what you get for your money might just make my headers the best value currently available. LT's or shorties.

ever get any vids or soundclips of your ride hooley?

Definitely like to see a back to back. Kleemann vs. MBH Longtubes. I was told by an engine builder and tuner that long tubes can cause a sudden spike in mid RPM power but you lose the low and high RPM range with a twin-screw Supercharger setup. Long tubes create a vacuum pulse from the merge collectors back to the exhaust valve port which causes this spike. So it's one big burst which can be lumpy and not a continuous steady but smooth flow like the mid-length Kleemann's. I also heard that it needs to be longer to be considered true long tubes for a C55.

Can you ask Richard or the other DynoComp guys about this?

hooleyboy

The power is very smooth and it though out the RPM range. It is true that our collector design along with the firing ordering sequences (I'm the only one doing that BTW) will create added vacuum in the header. In turn it makes the engine work a little less harder by helping to suck the spent gases out faster. The savaging effect these headers have is a really nice feature.

I'm awaiting a retune. Since I put these headers on. My A/F with this setup shows that ignition and a bit more fuel can be added to the tune. Thus creating even more power on a tune that was to the max before the new headers.

And dropping my boost to just over 5psi at redline form 7psi. While still putting down more power than my past setup.

I have a meeting tomorrow morning with Rich and the fabricator to go over the finalization of the E55 LT headers. I will for sure raise your questions.

I think with your monster setup you will pick up some power, However I do think the proof will be in the A/F. That will tell the tail if these headers can pick up more power over what I think they will gain without tuning for them. If more tuning is so needed.

mkonei

how is your engine coming?

AMGSC

Dropped by yesterday. Looking good so far. Car is schedule to fire up tomorrow.
Looking at options to tap the SC plenum for Nitrous jets now.

I should have taken some pics when I visited the shop yesterday. There was one section of the shop that was pretty badly burned and a big hole in the cieling where the fire burned through on July 4th.

I've got Brembo Red touches here and there on the motor. The 82mm throttle body modified opening is so much bigger. It's going to make a difference in intake velocity and flow.

AMGSC

Any updates on my questions regarding uneven air flow through these LTs?

blackbenzz

Hooleyboy- Have you done before/after dyno on your personal car for the headers? I too am interested in pre/post gains with the headers compared to kleemann since thats what I am currently running. Fitment is an issue but I could definitely use some bigger piping in their to match the rest of the exhaust andallow better exhaust flow.

Nice! I cant wait!

You want a direct port setup? How big of a shot do you wanna run? You can run a wet setup pre TB on the elbow pretty easily if the shot isnt too big.

Oh yes, much more flow. I maxed out my injectors doing that! What do you planon running in front of the TB? Still gonna run the 55k airboxes?

AMGSC

After the car is broken in. I'm thinkin a 100shot should be enough but will consider a 150 shot max. My pistons, valves, rings, re-coated cylinders and bulletproof tranny are all heavy duty racing variety so it should handle the boost with no problems. Vadim is thinking of applying the shots directly over over cylinder so you could call that a cirect port setup. As for the airboxes, the 55K airboxes are being replaced by custom intakes similar to the Fangs which are wider diameter wih cone filters. The injectors will likely be 60lb injectors but Vadim will see exactly how big the injectors need to be to support 21psi.

AMGSC

Hey Mike,
Got a proposition for you. If your LTs make 20whp or more over the Kleemann then I'll pay for them on the spot $2900 + install labor. If it only makes 10whp more, then I'll give you $2000, Any less than that and you put my Kleemann's back on with no labor charge. Do we have a deal?

SilverBulletAMG

Interesting. Not a bad proposition. Curious how this turns out.

MBH motorsports

I cant even get the headers made for 2K. I've fought tooth an nail to get them to $2900. IF these headers where installed at Dyno-Comp I would gladly cover the install/uninstall cost if they didn't make the kind of power.

JonMBZ

I would really like to see how much they gain as well. How much HP do the Kleeman put out anyways? I'm guessing 15rwhp ? So these are expected to put out around 35? As much as I would like to see the prices fall and the comparison Hooley doesn't make them himself so he cant really dictate the final costs which I do believe even though they seem really expensive are a legitimately good deal to begin with. I say give him a chance install them if they are not what you expected then put the Kleeman back on. You will probably not even get this type of luxury with any other tuner.

hooleyboy

I would love to see my headers pitted against any header on the market, win loose or draw, it would be cool to see. There are companies that will make these headers at a lesser cost. Much like other big performance shops do. I dont want to do that, the welds could be hit or miss, along with over all fit and finish. I would rather have them hand made by our fabrication team.

Once you get these headers in your hands can you understand the quality, time, and attention to detail that is put into each set.

AMGSC

I know that LET just began offering E55 long tubes in 304 Stainless for $1999. I believe you use a thicker gauge Stainless correct? Is it necessary? Does it add unneccesary weight relative to the additional durability?

hooleyboy

By no means was I referring to what LET does. I was referring to larger companies that send there prototypes out to be mass produced my a manufacturing company.

I think LET is using 16 gage 304 for the runners. As am I.

We use 321 SS for our flanges. The stuff maybe unneeded but it offers some piece of mind not having to worry about a flange crapping out on you. 321 plate stainless is super hard to find. Also our collector is hand made to the specs of the motor. You can buy collectors, but in some case you cant truly find one that is dead on to the specs you need. Just because the collector fits the size runners you are using doesn't make it the right collector.

AMGSC

Mike,
I'll take them for $2900 including tax. Now I just need to sell my Kleemann headers for $800.

hooleyboy

PM sent

AMGSC

I may have a buyer for my Kleemann headers. When I get my money I will send the car your way. btw....Need a firm quote on a full SL55 Kompressor install. if worthwhile, I'll sell my Kleemann twin-screw also.

sultanC36

hi are these headers still in production ? and is there any update on the price ?

Lt8x7

Will these headers fit on a RH drive car?
