BMW F34 320i GT ARMYTRIX Quad-Tips M3 Style Valvetronic Exhaust – Video

To be fair, you can’t exactly call the 320i GT a slow car. It’s got 184 PS and 270 Nm (199 lb-ft) and weighs around 1,615 kg (3,560 lbs), which means that it will hit 100 km/h (62 mph) in 7.9 seconds thanks to BMW engineering.

Those aren’t bad numbers at all – add the Armytrix exhaust, good for an extra 11.6 PS and 15.7 Nm, and the Armytron tuning box, which adds another 41.5 PS and 63.7 Nm and you end up with 237 PS and 349 Nm (257 lb-ft) coming from that turbocharged four cylinder engine.
