Header question I have not found an answer to....
Has anyone dyno'ed their car with any of the headers offered by Evo, LET or others with a before baseline and after? I am curious what gains people are actually seeing vs. assuming there are gains if any. I've thought about the mod since it seems like a pretty simple install for the DIYer. I'm kind of sceptical about the shorties really making a big difference and wonder what others think?

Not a pretty simple install. Unbolt the engine and retrieve the headers from the top. You can only pull them from the top side because of the way that they are routed...that is why you have to jack the motor up in order to get enough clearance...Second yes there has been a dyno for both. I can not remember who has the evos but he is partners with Erick at LET. I believe it is AMG jerry. He lost close to 20 hp with them and with out a tune. The LET headers have a gain of about 12. Erick has had both headers on his car and the LETs have shown more power and no loss. The log style just works better then the three into one.

Here is what he said on Crossfireforum.org It was only 15 not 20 my mistake.
I can assure you that these are not cheap knock-offs. The 3-1 collector headers for our motor make less power than the log style headers we are selling.
I have a set of Evosport headers on my car now. I lost 15whp after the install and have not gained it back, even with more custom tuning. I wasn't a fan of the log style until they started making proven power. If we had more room to work with, the 3-1 equal length headers would be the way to go....but we don't.

You are correct on the performance gains though, I gained HP with the LET headers but did not gain anything with the evosport headers...
Jerry lost HP initially with the evo headers but gained it back with custom tuning...
Let me know if you guys have anymore questions...

lol damn it that is the only thing that is stopping me from buying these headers or trying to make something like these I SHOULD HAVE BOUGHT A C32 lol jk i love my SRT.
C32used not a problem, some of you guys check in on the crossfireforum others don't. I'm not as familiar with posts on here as I am on there, I remembered him saying that so I knew right where to find it. I hope It i didn't come off as an I told you so feeling. I have read a lot of your post and your really enjoying reading about most of your track experience.

If it's available that would be great. If there is no dyno graph before and after, maybe offer a set of headers to someone at a price less the cost of a dyno with the handshake agreement that the Dyno graphs be provided to Erick @ LET (before and after) to show the performance gains. I might be up for the task. My engine is bone stock. Just a thought.

They are available for order right now...

can anyone explain why the evosport headers lost rwhp ?? Maybe Adam at evosport can help us out on this thread. Would people with these headers need to do a tune of there ECU in order not to see a loss

Yes, those who have Evosport headers do need a tune to maximize the performance gain.
However, it is best to do a pre mod dyno and post mod dyno with the evosport headers minus the tune. This way, we can have solid data before tuning the DME.

I would assume these gains were with a tune after the header install...Am I correct? Those are decent gains for shorties. On a GTO JBA shorties are claimed by JBA to gain around 20rwhp but some have doubts as to those numbers. I guess the design of the stock manifolds is pretty efficient.
Are the Evo and LET shorties CARB certified? Thanks.

I believe this is primarily due to the cost of going through the certification process, as the effect of the parts on the car's emissions would likely be negligible (perhaps even beneficial, due to the ceramic coating... might warm the cats up more quickly and efficiently).

While checking with the respective manufacturers is your best bet, I think ALL aftermarket headers (i.e. evosport, LET, Supersprint et al.) for our engine are for "off-road use only."

You are correct on the cost to get CARB certification being rather steep and the reason that more manufacturers don't get them.

https://mbworld.org/forums/c32-amg-c55-amg-w203/219107-letmotorsports-dyno-results-headers-make-power.html I don't know why they dont mention it on the site. MIND YOU this is the SAME set up that VRP now uses on the 55s I don't think everyone would go through all this trouble if they didn't make power. I remember the company that makes theres also making them for the SLK32. He was having problems with THE A/F ratio he wasnt getting enough fuel, I wonder if anyone has had this problem with the LET headers ?

Steve has a problem with his A/F being too lean; and we have added fuel. So far we are trying to resolve the problem and we suspect that he might need bigger fuel injectors, as the ones in the SLK32 might not be enough.

Is this a problem because of the headers? I guess this is the first I have heard of anything like this are all the new style headers sucking too much of the exhaust gases? If the injectors are having problems with not getting enough fuel do to changing headers I WONT EVEN START A THREAD ON OPENING THE QUESTION OF CONVERTING TO E85. All my friends with there CRX's, talon's, and now EVO's are converting I wanted to hop on the band wagon... they seem to think a larger fuel pump maybe some new injectors and an APEX system will do the trick AM I

That would be an issue in CA as the smog jockeys will look for a CARB exemption number unless you find a "friend" at the smog station. For GTOs, the JBAs and Edelbrock shorties are the only CARB certified headers that can be legally installed in CA.
You are correct on the cost to get CARB certification being rather steep and the reason that more manufacturers don't get them.
