Stainless steel exhaust system in cat back configuration consisting of a pair of 200-cell catalytic converters that eliminate FAP, non-silenced central silencer, rear silencer equipped with valves managed by the standard system and anodised aluminium terminals covered in carbon fibre.
The system is specifically developed for the M3 G80 and M4 G82 and is also compatible with the Competition and xDrive versions

The introduction of the FAP has made the voice of the 6-cylinder M difficult to recognize. The sound is unsatisfactory for true BMW M lovers.
To do justice to this impressive engine from all points of view, we have created a hand-polished 309 stainless steel exhaust system consisting of a pair of 200-cell FAP-eliminating catalytic converters, a non-silenced centre pipe and a rear silencer equipped with valves controlled by the BMW management system.
The final part is composed of 2 pairs of anodized aluminium terminals covered in carbon fibre.
Thanks to a design based on reverse engineering, we are able to create a line optimised in terms of dimensions and exhaust flows. We start from a laser scan of the original exhaust line of the car and then create the CAD model. From this model we obtain the dimensions and dimensions that are useful to us. We then go on to create our CAD project and the first prototypes.
Thanks to this process we manage to not vary the original back pressure values while improving the acoustic output and performance. The valves are managed by the BMW series system.
NOISE AND PERFORMANCE RESULTS
Noise increase:
Series exhaust (open valves): 102 dbA
Capristo (open valves): 126.7 dbA
Power increase:
Series exhaust: 519.7 HP at 6024 rpm
Capristo: 532.3 HP at 6470 rpm
Torque increase:
Series exhaust: 693.4 Nm at 4186 rpm
Capristo: 708.6 Nm at 4062 rpm
With the valves closed the sound is the same as the standard car in terms of volume and sonority.
