BMW M5 F90 exhaust on the S63B44T4 engine is a complex factory system: turbos, OPF (Otto Particulate Filter for gas engines), active valves, resonators. Out of the box, M5 sounds different by Drive Mode, but actual volume is capped by European noise regulations. Modification gives M5 the "voice" BMW engineers built in but couldn't deliver due to regulations. Here are the options from light tuning to full straight-pipe.
Modification stages and labor cost
Stage | Included | Labor, ₽ | Sound effect |
|---|---|---|---|
Valve unlock | Software unlock of active valves | 25,000 – 45,000 | +15–25% |
Downpipe | Sport downpipe replacement (catless or sport-cat) | 60,000 – 110,000 | +30–40% |
Mid-pipe + OPF delete | Mid-section replacement, particulate filter delete | 90,000 – 160,000 | +50–65% |

What else affects the quote
ECU tune. After downpipe — ECU reflash needed, otherwise lambda errors and power loss. +30,000–60,000 ₽.
OPF delete and certification. In Russia particulate filter isn't on the mandatory list as of 2026 — delete is legal. In EU it's a problem. +10,000–20,000 ₽ for documentation.
Sound tuning. If exhaust ends up too loud — extra resonator between sections. +25,000–45,000 ₽.
Stock retention. Keep OEM system in storage — recommended for resale. +5,000–8,000 ₽ for packaging.
Timing
Valve unlock — 1 day. Downpipe — 2 days. Mid-pipe + OPF delete — 2–3 days. Full Akrapovič — 3–4 days (including ECU tune and test drive).
FAQ
What adds power?
Exhaust alone without ECU tune gives 5–15 hp. ECU tune for modified exhaust — 30–60 hp more. Full Stage 1 + downpipe + Akrapovič — total 670–720 hp on stock hardware.
Can I revert to OEM?
Yes if original system is preserved. Critical before dealer resale or warranty reset. Reverting — 30,000–50,000 ₽ labor.
What about warranty?
Any exhaust intervention formally voids engine and transmission warranty. If M5 is under warranty — wait until expiry. If past warranty — no constraints.
Is the Akrapovič sound difference real?
Akrapovič Evolution Line on M5 F90 is another class of car. Sound becomes "race-track," especially cold and in Sport+. Idle — bassy growl, on throttle — sharp rise in mid-RPM. We have a test M5 with Evolution available for listening before order.
