The 2013-2018 BMW F12/F13 640i, and the 640i xDrive version may be considered as the entry level models in the BMW 6 Series lineup; regardless, they have a huge performance potential.
The key feature is that the mildly tuned N55 engine found on the 640i is shared with the BMW Motorsport's own M2, N55 powerplant.
Getting the same performance is only a few modifications away.
Supersprint did its part, having developed an oversize diameter, free-flowing full exhaust, including the Turbo Downpipe, which matches the exact potential of the engine.
By simply adding a M2 Software upgrade, and bolting on the Supersprint full exhaust, the 640i immediately jumps to 420 hp.
Yet we did not stop here, as we offer a larger diameter exhaust still, to complement futher performance steps of 420 - 470 Hp.
The Supersprint exhaust is available in multiple options, thanks to the modular design of each of its individual components.
We have resonated, or straight mid sections, and a wide choice of R&L rer mufflers, with single outlets, or quad tips.
