Mugen Sports Exhaust System Honda Prelude BF1 26+
The Mugen sports exhaust system replaces the BF1 Prelude’s standard rear silencer with a full stainless steel system tuned for a stronger, more characterful sound.
Mugen developed it alongside the Prelude’s Honda S+ Shift function, aiming for a sound that builds in a linear, engaging way as the revs rise. The tailpipe finisher has a black finish with a laser-engraved Mugen logo. In Japan it is certified under the pre-approval scheme for replacement silencers that meet the national vehicle safety standards.

Fitment
- Honda Prelude BF1
Not suitable for: fitting without the carbon rear diffuser 84120-XPD-K0S0, earlier Prelude generations, or the Civic Type R FL5, which needs the Mugen FL5 sports exhaust.
Installation
Mugen quotes approx. 0.7 hours to fit, working to its installation instructions, with the car safely raised on a lift. Important: Mugen states the exhaust cannot be fitted on its own. It must be installed together with the carbon rear diffuser for the sports exhaust (84120-XPD-K0S0). Let the system cool fully before working on it. Professional fitting is recommended.
Do I need anything else to fit it?
Yes. Mugen requires the carbon rear diffuser 84120-XPD-K0S0 to be fitted with the exhaust. It cannot be installed on its own.
How loud is it?
It is noticeably sportier than standard but designed to stay within Japan’s noise rules for replacement silencers. Mugen does not publish a decibel figure.
Is it road legal in the UK?
It is certified to Japan’s replacement-silencer standards. UK rules differ, so we recommend telling your insurer about the modification.
Does it add power?
Mugen develops it mainly for sound and character. It does not quote a power figure, so we do not claim one.
