Getting American Racing LTH installed in ~2 weeks and wondering if anyone has a custom flame tune with headers through eurocharged? The idea sounds silly but also super awesome so thought I'd see if it can be done safely ha!

My setup will be ARH headers, secondary and resonator delete. Feel as if it may be a tad loud with resonator delete also so might get resonator put back in.

Don't delete resonators, its loud as ***** and I have the catted variant. Car sounds exactly like that "oh my god/my ears are bleeding!" video of the white 507 with the mhp/arh headers. They are awsome and it really completes the car.

Mine shoots a little flame with MBH headers on down shifts lol

ar headers

We're glad you're going to be using our headers on your car. As far as a tune, there's nothing safe about spraying an excess amount of unburned fuel on decel to the point where it's igniting at the tail pipes from heat. This causes excessive wear on engine components as well as sensors, piping, etc. (Assuming you don't have cats as well). It may look cool, but you're basically turning your Mercedes engine into a replaceable item. We all know how reliable these cars are with a grandma driving to begin with.

Thank you for the response. Was just curious if it was safe in any form and I suppose the answer is no! Looking forward to getting your headers installed when they arrive! Just ordered last week.

I sent you a PM regarding some mid-pipes about a week ago with no response. please check your inbox.

Hahaha that's my 507. My setup is ARH no cats, with OEM res and OEM mufflers. Sounds amazing. Humble yet loud when she wanna be. Shoots flames around 4k if racing the car hard, etc on the EC tune.

That video is almost the main reason I got the car. Definately the reason I went with ARH. I still watch that video every now and then.

I would say they are unsafe if its tune to do it.

Its OK if the car back fires here and there, or if you lay on the rev limiter for a few sec coming out of a corner and exhaust is hot and ignition cuts and then there is surplus fuel. That's another story. But I think engineering a tune to shoot flames, wont end well. There is a difference between a few pops / flames VS a severe flames constantly shooting out. I wouldnt do it

I few pips and flames shouldn't hurt a good Stainless Steel exhaust. We aren't dealing with a 2-step or anti-lag system.

Came along to search about flame tunes, thinking (again, as all others) it would be super cool, but got convinced otherwise for all the previous stated reasons. Anyhow, anyone with the tune on, care to share the feedback?

NotABaller

I think the issue here is the definition of flames vs backfire (pops). In my opinion

Flames = 1 foot (or longer), extended duration. This is basically dumping in fuel. Total ricer mod on our cars, and probably not good for the car.

Backfire on decel = short pops and bangs that most of us already have. But the complete removal of the exhaust system allows those pops/bangs to also ignite a fire in the exhaust. I think this is fine

Is my understanding correct?

Vpatriota

Yes yes, I might've misspoken what I was thinking. I'm not into that Lambo-flames (even though I find it cool as hell - in someone else's cars, ofc, no mine), but about that back fire. We don't usually see it with the 6.2 AMG V8, right? I think you have to program something on the ECU for that to happen?

I've had the flame tune on for quite a bit. It definitely after-fires incredibly loud, sounds like a gunshot in your ear. On average, you can't really tell it has the hot-tune, but when you run it to redline and let off the throttle it shoots a ton of flames. If you lightly get back on the throttle at a high RPM it jerks quite a bit, like an aggressive blip, but it shoots even more flames and makes a ton of racket. The only negative side effect is what I mentioned about the throttle blipping, otherwise it drives like the standard tune.

I agree that dumping fuel into the exhaust for the sake of making noise is not as healthy for the engine as a regular tune, but cars have been doing this for decades and see little to no downside. Every WRX/STi, Evolution, Golf R, and 335i hotboi has had tunes like this for year without any side effects. My 0.02, but everybody has their own opinion.

NotABaller

Have any vids of tailpipes shooting flames for us please?

JonM

Unfortunately, no. My buddies who have been behind that car said it shot fireballs basically as wide as the rear end. I have 630cc injectors in, as well, which probably leads to even more fuel being thrown out the back.
