Porsche Dragon Afterfire.
Flat-six theatre, calibrated. Pops and bangs, burble and flames-on-demand for the 992, 991, 718 and beyond — developed in Tokyo, proven across Japan’s largest network, supplied worldwide.
What we do to a Porsche
The flat-six is one of the most characterful engines ever built. We make it theatrical — without touching the fuelling.
Dragon Afterfire
Real flames on lift-off and overrun, produced purely through ECU calibration. Our signature.
Pops & Bangs / Burble
From a refined flat-six crackle to full aggressive overrun. Tuned to the car and its exhaust.
PSE-aware tuning
We calibrate around the Porsche Sport Exhaust valve behaviour, so the character lands where you want it.
ECU tuning
Optional power & response gains alongside the sound — turbo 911s respond especially well.
The mbFAST difference: engineered to last
Anyone can make a car pop for a demo. The difference is what it costs the engine. Our calibrations are developed in-house in Tokyo and run daily on thousands of cars across Japan’s largest pops-and-bangs network — maximum theatre, with the engine and catalytic converters protected. Daily-drivable, switchable, and fully reversible.

FAQ
Is this safe for a Porsche flat-six?
Yes. Every calibration is developed and validated in-house, and runs daily on cars across our nationwide network — tuned for maximum sound with engineered margins that protect the engine and catalytic converters.
Does it work with PSE (Porsche Sport Exhaust)?
It does — we account for the sport-exhaust valve behaviour so the pops and afterfire land as intended, valves open or closed.
Which models can you do?
992 and 991 911s (Carrera and Turbo), 997 turbo, the 718 Cayman/Boxster/Spyder, plus Macan and Panamera for sound tuning. Ask about yours.
