Mercedes w124 300e M103 Straight pipe exhaust sound LOUD with EFI conversion

A few revs with the new EFI Coil On Plug ignition setup, controlled by a STANDALONE ECU EasyEcu 3 with the conversion kit from k-jet killers Poland. It is more responsive and rev-happy with this kit, and mainly due to an aggressive ignition map it is much more powerful in the higher revs. Smoother engine operation with a seemingly better torque curve. I use NGK U5014 ignition coils (COP) wasted spark, Bosch original 190ccm injectors, all original sensors, 60-2 trigger wheel, VR sensor at ~ from the wheel. Original Mercedes narrowband o2 sensor. Rev counter is now connected. This is without any muffler, sound is straight through the catalytic converters. The main and the 2 secondary cats behind the exhaust manifold are still in place. This was just for fun, I still use the same exhaust setup as my older video. Only the backbox deleted. The engine I have is the , came original in my mopf0 1987 300e. #mercedes #benz
