Mugen Titanium Exhaust System with Side Spats Honda Civic Type R FL5 23+

Mugen’s sports titanium exhaust is the Group B exhaust for the FL5 Civic Type R. It was developed from the front pipe back, with a larger-diameter front pipe to improve mid-range torque.

The main system is titanium with a stainless steel front pipe and a single centre finisher. Mugen quotes it as approx. 8.75kg lighter than the standard silencer. It is certified under Japan’s pre-approval scheme for replacement silencers that meet the national safety standards, and comes with an active exhaust valve canceller for the standard valve.
