How to Make BMW 318is Exhaust System Shoot Loudly Like at Toruń Rally?

Hello to all forum members and automotive enthusiasts.
Does any of you know how to convert the exhaust system in a BMW 318is so that it shoots loudly? After putting the engine at high speed until the ignition is cut off, the silencer shoots loudly ... I saw something like this at the BMW rally in Toruń and I did not manage to catch the owner of the car to ask for a diagram of such an effect.
I wanted to install something like that in my BMW but nobody can tell me how it is done ... I was recommended FLAMER KIT but that's not what I mean so I was directed to this forum. Apparently, they know everything here, so I'm waiting for a reply and thank you in advance and best regards

It's not as easy as it sounds and goes deep into the topic of engine and ECU rework. Forget it because it may cost more than the car is worth.

Welcome
Much cheaper and more effective, if you stick to the glass "I'm from the village"
Forgive me for the tone, but it makes me sick to see such a show-off under my windows. It used to be like that with little ones, the ignition is turned off in the rush and after a while, it turns on, it hits like a cannon, the BMW will certainly be able to do that too, but if the muffler will last .........

And this photo is for what?
This sort of thing could only be done in jigs with a primitive carburetor.

bobo23 What was this BMW?

I will not speak about my colleague Kunnikutan because everyone will determine what he represents ...... and the I AM OF THE RURAL sticker is carried on the rear window by himself. Not to mention the photo he pasted ...... probably by mistake.


Returning to the topic, it was the last version of the E30 with a good engine, I suspect with at least 2.8 I was at the Majówka in Toruń but unfortunately this year it was not there.

The sower in these days with engine and ECU modifications is no problem and it is not so expensive, there is no shortage of parts in Poland and I have an ADS interface myself, which goes to INPA, just tell me what you need to do to get this effect ???? if you know, share the news, I will be very grateful to you ...
I mean shots from the exhaust with the ignition cut-off of 6,500,000 engine revolutions.

Water before the section and delay the ignition to the maximum and then you can order a muffler as a spare

The basis is you must have free passage on the exhaust.
Forget about the catalyst because it will crash it.
There are companies that make slow exhausts for cars.

A buddy was making such a fairy tale in CBR and it turned out nice for him
The engine was on injection and computer-controlled, introduced a modification that instead of cutting the ignition at 8, it delayed it slightly.

In general, when it comes to the effects, the trail will quickly hit the valve seats and the valves themselves, not to mention the burned piston crown
You can buy IR immediately, because the usual ones will not serve you for a long time ;)

Hymn sometimes a BMW passes through my town, which when changing gears, it shoots nice not only with fire from the end of the exhaust system, but the same detonation can be heard and I was also wondering how this effect is obtained

... I don't know that, but when people like you ride my quiet neighborhood street at night, I throw bricks, I have a supply from the construction site ...

... it is not about shooting and pounding all the time while driving because I would not be able to withstand such a ride, but I only mean that the shot would be when I put the engine at maximum speed ... there is a section and then the shot from the silencer ... ..


... KUBA ... if you succeed, ask the owner of this car how he managed to achieve this effect. Maybe something will tell us what to do.
On Wednesday I go to the dyno for calibrations, maybe we can get something.
