Machined sound ring compressor housings. Amplified turbo sound from the factory S55 turbos.
T51R sound ring compressor housings for the BMW S55, made as a direct replacement for the factory compressor covers. The machined ring at the compressor inducer amplifies the sound the factory turbos already make.
Why it’s built this way
- Machined T51R sound ring at the compressor inducer.
- Cast aluminium with CNC-machined mounting and sealing faces.
- Direct replacement for the OEM S55 compressor housings.
In the box
- Pair: front and rear turbo housings, one per turbocharger
- Rear turbo housing only: the single housing for the rear turbo
Good to know
- What to expect: a louder turbo note from the factory turbos. It doesn’t add a flutter or blow-off sound, and it isn’t a power upgrade.
- No retune needed: boost targets don’t change, so your existing tune carries over.
- Best with an aftermarket intake: the factory intake damps turbo noise. Our S55 cold air intakes suit it.
- Fits: F80 M3, F82/F83 M4, F87 M2 Competition (2014 to 2020).
- Install: professional install required.
- Warranty: 6 months, manufacturing defects only.
- Lead time: made to order, ships in 7 to 17 days. We confirm your dispatch date by email.
- Off-road / motorsport use only.

What does the T51R mod do?
