Back in the 1990s, the BMW 8 Series was the big coupe from Munich that had the grueling task of going up against the best of other manufacturers. The 6 Series was enjoying a 24-year long hiatus and it was all up to the 8 Series to keep the blue and white flag up in that particular segment. To get a better idea of how luxurious and big this this was, you need to know that the BMW 840Ci was the entry-level choice for the 8 Series.
And yes, back then, the numbers on the boot did stand for the engine’s capacity, the initial 840Ci using the M60 4-liter V8 under its hood, good for 286 HP and 420 Nm (310 lb-ft) of torque. Today those figures can easily be achieved by 2-liter turbocharged 4-cylinder engines but back then, they were impressive, to say the least. What we just found is that, nearly 20 years later, the 840Ci can still hang with the big boys, at least in terms of exhaust sound.
To be perfectly frank, a little help is needed but considering the car’s age, but I’d say it deserves the little push. That push comes from the guys over at Supersprint that fitted the car in the video below with one of their complete exhausts made of stainless steel. The kit is made up of two manifolds (one for each cylinder bank), front metallic catalytic converters, center crosspipe, connecting pipe for the rear muffler and 90-mm exhaust tips.
The best bit about this exhaust is that it is available today for those that still have 840Ci models in their garages and that it makes the car sound just right, as you can hear and see in the video below. What’s even more surprising is that after all this time, the dyno readings of the guys from Superspring show that the engine is still making 284 HP and 390 Nm (288 lb-ft) of torque.
