I have been speaking with Kleeman about possibly purchasing a set of their stainless headers.

They quoted me $4,100 and said they are fully stainless steel and require some tig welding because they do away with the primary cats on the car.

Does anyone have any photos or experience with these headers? Is this the best price they are offered at?

Thanks in advance.

 

Here are some pics.

 

Something I notice that is a little weird.. The header on the left doesnt look to have equal-length bends on the tubes. They all seem to merge into one-another while the header on the right seems to have all equal-length tubes merging only at the bottom where the collector is.???? Never seen that before on a header.

Do you have them on your car by any chance? Any idea of what type of performance gains to expect?

I have been hearing from alot of different sources that headers on our cars yield around 25 - 30 rwhp. I know the factory 90degree pipes are very restrictive so I have high expectations for how the car will feel once they are replaced.

I would like to do the header swap and then decide if I should go the next step and do the cat-back exhaust.

Thanks again!!

 

So now that we have seen Kleeman, Stephens, and evosport's, which set of headers look the best?

 

More importantly which work the best. Both Evosport and mine work with the cars current cats in place. The Evosport units don't require any welding and appear to be a true bolt in proposition, where mine need a new flange welded before the first cat.

 

BUYER BEWARE

All I felt it was necessary to inform the E55 comminuty of a Merchant that has failed to ship a E55 kit containing a pulley upgrade, cooling system, and headers upgrade.

I think this board should know this information so that you do not have to deal or suffer a financial loss or headaches.

I will periodically inform the board on this matter for your own protection as to the status of the refund.

Additionally I would hope we could start a thread on merchant reviews, kit reviews, customer service, etc.

<<Update on Stephen's 540rwhp Kit>>

Let me inform all of the facts so that everyone is very aware of this merchants activities and reliabliity.

Note: I realize I am a sample size of 1 but when I earlier attempted to see if anyone else in the US had purchased and acquired his kit I realized that I was likely the only person that had purchased it. Stupid me. So I will leave any inference of fraud or deception up to you but here are the facts:

Order Date June 26th
Purchase Date: Paypal $6,300
Date promised: 2 weeks (10 days shipping via TNT)
In stock amount quoted: 6 kits


Contact on my part to Stephen: 71 e-mails, 33 phone calls ($398 from home - rest from office.

Shipping/Tracking #s provided by Stephen: 2 bogus #s that do not register anything on www.tnt.com

Reason #1: Stephen Claims it was shipped. I verify by TNT's #800 number of no such shipment. Later Stephen says it was stolen by an insider.

Shipment #2: Stephen says customs would not pick it up.

Refund: Stephen attempted to issued refund but my bank said there was no such effort made. His reply: It won't go through internationally.

Refund #2: He would not refund via paypal because it would cost me $256 in a transaction fee.

I hope you all get the picture that this merchant is likely highly unethical and/or highly unresponse to customers. So far its been a nightmare dealing with Stephen as all I have to show is headaches and a loss of $6300 so far. My bank is now on the case.

While I can only speak for myself I would high restrain from ordering or dealing with this merchant. On a 1 to 10 I would rate my experience a complete zero. Please take heed and caution in dealing with this merchant. Its sad because if his kit exists (I have no proof it does) it would have been a decent buy. BUYER BEWARE.

 

Stage 2 upgrade kit for W211 E55 AMG, You can see clearly that the Kleemann header is much longer than the competitors'. The actual result of the kit is amazing.
