Exhaust F87-M2 Competition S55 engine prototype

The specifications are designed with tuning in mind.
The know-how of the F82-M4 exhaust is used, but the silencer layout is individually designed for the M2 Competition.

The diameter of the main pipe and exhaust flap is 70 mm.

Rear silencers have a lot to do with performance.
In Sports Plus mode, the exhaust flap is fully opened and exhaust air passes through both the straight pipe and the rare silencer. Therefore, rear silencer performance is important and the structure is designed for high exhaust efficiency.
IN COMFORT MODE, ALL EXHAUST PASSES THROUGH THE REAR SILENCER AND IS MUFFLED TO ABOUT STOCK VOLUME. THE TONE IS A SPORTY SOUND CHARACTERISTIC OF THE LAPTORR.

The middle pipe is unequal length to optimize performance and tone.
