How much can N/A M156s make?
Hey guys,
What is the maximum power you can make on an N/A M156 WITHOUT long tube headers or even shorty headers, only log style ones like the PLM ones which are like OEM but just bigger.
I'm curious because I live in a place where loud cars are heavily descended upon AND you cannot remove the cats, primary or secondary. Plus, LTHs in my opinion give the car a really raspy sound. It sounds amazing as a track machine but it could get a little tiring after the novelty wears off. I heard a straight piped LTH M156 go past at WOT once and the thing was deafening, just deafening, it made me nauseous. I know I'll get hate for this, people seem to worship LTHs.
Again, just entertain the idea for a second with the "rules" stated. Anything goes EXCEPT exhaust (PLM headers allowed).
Let's assume you can run E85 though. I'm just curious as to how far the M156 has gotten in NA power and how important LTHs are.

You're going to be limited to what a tune gets you. Log style and what not aren't worth it.

FBO M156s put down from 470-485rwhp on a healthy motor, with at least 30rwhp or a little more coming from LTH's. That N/a motor is already hard and expensive to get power out of so with out LTH it's pretty pointless searching for power unless you spray a 50-75 shot of nitrous or something.
i understand what you mean with the sound though, I loved my M156's sound but it did become obnoxious as a DD, early am cold starts, cruising through neighborhoods or even pulling off normally from a light it sounds like a monster.
Sold it and got a M157 all said and done but the M156 sound is king for AMG to me besides the 7.3L N/A AMG V12 in the zondas.

It's a legal thing too though. It depends on where you live but some places, they will make your car unregistered until you take them off and you can easily see headers if you know what you're looking at. Taking off cats also carries BIG fines. So even if you drive with them on and you get asked to take them off, your car is unregistered until you take them off which is not easy, as you know.

Depends how much you're willing to spend I suppose. I agree that log manifolds are probably not worth it so much. A decat can get you close to the peak gains of headers, but you'll not have the mid-range. In this instance I would recommend sports cats to keep the sound reasonable and to gain some more power with the tune - the E63 has two very restrictive cats, whereas the C63 cats aren't so evil.
To attain more power, you can venture into cams, airboxes, big throttle bodies etc, but yes that can be expensive. Just depends how die-hard you are.
FWIW if ethanol is an option for you locally, you can get tuned for ethanol and attain around 470whp without touching the exhaust system.

It's an ethanol flex fuel kit that Eurocharged supply. generally you can expect to see 470whp without touching the exhaust. Headers fitted will see you well above 500whp. sports cat may well be enough to touch 500whp.

That's pretty good actually. What if you got ported heads and/or throttle body along with minor headers like PLM ones and those UPD filters etc and the ethanol kit but without long tubes, do you think that would get you to around 500whp. By the way I realize 500whp is meaningless as every dyno is different and some will read low while some high. Also I realize headers make some power but they're easily seen and easily heard, so are cat deletes (probably even more so), in some countries you get away with it but not where I live, they would love to tear a chunk out of my wallet
I'm making a custom intake for my car so I'm happy to sell you my UPD spacers for cheap if you like?

Does the intake spacer do anything. I remember seeing that infamous thread where people were trying to make it seem like snake oil but then again, I've seen some of the tuning companies put it on the M157s with turbo upgrades so why would they if it didn't do anything.

Will sport cats pass emissions testing do you think and will they make the car louder?

I never dyno'd the spacer so who knows.
Yeah...the W212 just loves to dyno really low doesn't it? 430whp should be the 'stock' figure for the car, let alone tuned.
