Just taken ownership of my new silver E55 AMG, pictures hopefully will be posted shortly

Wanted to know which long tube headers require the minimum of alteration to the existing exhaust set up, as this is top of my list of next mods, plus should I get a custom retune afterwards....

Are Supersprint headers are a simple bolt on or is this taking a naive view

Just my opinion, but headers aren't worth the money and effort for the little HP improvement you get. The exhaust manifolds on our cars are pretty good from the factory.

headers that give 40+ rwhp aren't worth... what does worth the money then!?

The stock exhaust manifolds are one of the worst OEM pieces among all the performance parts in these cars. It is very restrictive and does rob you out of some good horsepower.

To the OP, Chris at Floored Fab makes a nice set of long tube headers that seem to be proven on the dyno and the track.

Thats what Im thinking.

I think I'm going to be a test mule for a new brand of long tubes. That is if I find a way to get my car to them. Supposed to make 30-40whp, over stock.

Have you seen the crappy logs that MB passed off as headers on this high performance engine? The ID is only about 1.5". If there was just one thing I could change on the engine, the headers would be it. Even a set of shorty headers would be better than the stock setup.

40rwhp is definitely worth the investment, only question is there a long tube headers solution out that is a plug and play, rather than having to chopping the existing exhaust.

Are the Eurocharge long tube headers a viable option, was also looking at Supersprint amongst other stainless steel solutions.

Being based here in Dubai, looks like only option is importing, can the UAE E55 boys chime in with their views

The AMG mufflers are very good, so I would think you would want to keep them

The SuperSprint system is very good but also very expensive. If you purchase their entire exhaust system all the way to the mufflers, then you won't need to cut your exhaust at all.

Long or short, headers are a great option. Not only do they offer bolt-on power, but offer deeper tune-ability. The exhaust manifolds on these cars are not that great. When You are adding about 45whp from a single mod, thats quite the gain. In fact its about the same Horsepower gains you would see with a pulley and tune, pending on the pulley.

With that said, these days headers have become one of the top three mods people do to these cars.

WOW!!

He must be kidding.

If not......

So, you guys think you're going to see an 10 or 11% increase in HP with the addition of just headers? Keep on dreaming.

BenzoBoi

Long tubes and a good tune will get you that no problem...

speedpeddler

You could probably see 50 hp with stock exhaust and a tune. Headers alone won't get you squat.

BenzoBoi

Hold up...are you sayin that with a only a tune, you can see 50 hp?

speedpeddler

Yes. Talk to Jeremy at CE Tuning, (818-574-5075). Last time I spoke with him he pretty much guaranteed me 50HP on my STOCK E55 with just his tune.

blackbenzz

Do a search, plenty of proof of longtube header gains. And they are substantial even without a tune.

BenzoBoi

A set of Long tubes along with a tune will get you 40+ WHP EASY. There's the 10% hp increase you think I'm dreamin of.

Is this THE Jeremy? If so, you don't need to explain, he's the one that tuned my car. He does wonders on the 55k motor. There are quite a few of us on here that have been tuned by him and all the cars are running strong and healthy.

grantwoodtx

+40 RWHP from headers isn't worth it?

speedpeddler

Not saying headers won't help but a 10 or 11% increase just isn't going to happen without a tune to go with them. And, the majority of that increase is going to be the tune, not the headers.

If I were adding a pulley, throttle body and tune, then yes, I might spend the money for headers. But, they would NEVER be my first mod.

I've done my research, in the field, where it counts. All my Hot Rods have had headers for the past 40 years so I'm familiar with the results.

I'm not beyond being enlightened however, so show me a dyno sheet with a 50HP increase with headers on a STOCK E55.

This was the easiest one to find, but there have been others posted. Also, the stock exhaust manifolds on these cars are tiny and really not that great. Even replacing them with a nice HEM will make a noticeable difference in power.

Just found this one. A recent dyno with only shorties, no other mods: https://mbworld.org/forums/w211-amg/...no-inside.html
