Fujitsubo A-S Axle-Back Exhaust System Honda Civic Type R (FL5)

Fujitsubo A-S Axle-Back Exhaust System - Honda Civic Type R (FL5)

Fujitsubo is one of Japan's most respected exhaust manufacturers, combining precision stainless steel fabrication with real-world performance data. The A-S series sits at the top of their catalogue — a street-oriented, high quality cat-back system built around tonal character and visual impact as much as outright performance. For the Honda Civic Type R (FL5), it delivers a genuine step up in power and torque while keeping daily drivability firmly in mind.

This listing covers the Fujitsubo A-S cat-back exhaust system for the Honda Civic Type R FL5 (chassis code 6BA-FL5, K20C engine, September 2022 onwards). The system ships with dual 118mm titanium finisher tips as standard. An optional carbon fibre 118mm finisher is available separately as an upgrade.

Important: This system requires cutting of the factory exhaust during installation. The OEM electronic exhaust valve is non-functional once this system is fitted — a valve canceller is included in the kit to address this. Installation is recommended for experienced fabricators or specialist workshops only.
