Actually, they're HEMs or Hiflow Exhaust Manifolds. Vadim and VRP Tuning has just lightened my wallet and is crafting a set of these for me as I type this.

Stated gains for M113 N/A engine is 15-20hp, at the crank, if my car was stock. My car is not stock.

Wish me luck as this is going to be a DIY install.

What are the expected gains?

Benz-O-Rama

Third sentence in post #1. Barry, your eyes are getting worse in your old age.

15-20hp at the crank on a stock E500.

You are running out of mods to do-------maybe a little (10lb) blue bottle to come?

Benz-O-Rama

Shhhhhh

That's one that nobody will know about.

i almost pulled the trigger on the kleemann ones with an ecu tune but found $2k could pay for other more important things at the time,how much do these run if you dont mind me asking??

PM Vadim, he seems to be a very good guy and easy to work with. And he's one of the most respected tuners in the industry, from what I can tell.

gikser

cool thanks they are exactly the same price as the kleemanns on sale i wonder if anyone has these and can compare to kleemann?? not trying to be cheap but more of a smart buyer

Dang Benz-O you you beat me to it! I'm about to pull the trigger next month. Hope you post a DIY for the rest of us! Good luck

You will love them, they really wake the engine up, especially with the ecu software. I've had them for about two years now and still the best mode that I've done. Get them on as fast as possible.

Benz-O-Rama

You've had these EXACT VRP shorty's on for two years? What kind of gains did you see?

Benzo have you thought about dyno'ing your car? It would be nice to see a before/aft for the headers... or just to see where you're at with all the mods

NCE500

I'd say you've got a serious case of the mod bug; I've personally encountered cycles of same with various rides from time to time, it is addicting and always fun.

For what it's worth, I think adding these headers would complement an E55 airbox quite nicely.

Have fun and keep us posted.

I did dyno the car a couple of weeks ago at a dyno day. It was sponsored by another sponsor from another board.

Unfortunately, their printer wasn't working at the time so they couldn't give us our numbers on paper but if I recall, I was putting down 269hp and about 300tq at the wheels which when you account for drivetrain loss you get 269/.82 = 328bhp and 299/.82 = 364tq. Sounds about right, for my mods. I've been bugging the shop to get me the numbers but they're flaking out. At least I have something to go on.

I'll definitely do pre/post dyno for this mod.

phatmitzu

Good stuff.
ALWAYS bring a memory stick to the dyno. Get it on electronic file.

nikon

I had them custom build. As far as I can remember, nobody offered them. The true potential came after I did the ecu software. I did dyno it back then and the hp numbers are right there. After doing my calculation for loses, it turned out to be 18hp at the crank. I can't find the paperwork(dyno sheets and calculations), have been looking for it for the last two hours. I will look for it again, and if I find will pm you. Good advise from phatmitzu. I will dyno it again in couple of months. When did you get the e55 air filter housing? Did you see any improvement worth getting it?

Benz-O-Rama

Yeah, I was wondering because VRP didn't even start making these until last Summer. I was trying to catch you in a fib.

I have the AMG airbox in hand, just not installed yet. There have only been a few people that have done this mod, but have claimed a SOTP increase. I figure it couldn't hurt, so I'm gonna give it a shot. VRP now offers a slick looking "fang" intake, so I might give that a shot.

Will have the headers in a couple of weeks, then pre/post dynos. But then I'm going to Trinidad & Tobago for 2 weeks so I won't have anything to report until mid-march, if I had to take a guess.

Stay tuned...

GreekE500

The AMG airbox is mostly for sound and looks, maybe a couple of HP.

155

UH OH... check my sig hehe forget bluetooth/command etc time for some go fast mods!!

Benz-O-Rama

OUTSTANDING!

This is actually a good chance for us to determine what the gains are on a stock E500 and a slightly modded E500. You are going to do a pre/post dyno, right?

nikon

Just make sure that you install the headers first and then dyno the car. And after that install the amg air filter housing and dyno it again. Therefore you will precisely see what are the gains on each mod. I made a mistake by doing a couple of mods at the same time.

Benz-O-Rama

Since I don't expect much from the airbox, I'll probably pop that on and dyno. Then dyno again after the headers. No need to do a separate dyno just for the airbox. But if I decide to go with a under-drive pulley setup, then I'll have to dyno it again.

155

Just PM'd Victor about pricing... wonder if we should've done a GB? Yes, will do seperate runs stock and w/headers.

Benz-O-Rama

He was expecting you. I told him a Canadian gentleman would be in touch.

Pricing will be good, trust me. You're getting the "Clayton is the mack daddy" discount.
