Invidia R400 Single Layer Titanium Tip Full Catback (Non Polish Pipe) – 2023-2026 Honda Civic Type-R (FL5)

R400 Gemini Single Layer Titanium Tip Cat-Back for the 2023-2026 Civic Type R FL5

The Invidia R400 Gemini Single Layer Cat-Back with titanium tips for the 2023-2026 Honda Civic Type R FL5 steps up from the Q300 with the R400’s more aggressive muffler tuning and the Gemini’s independent per-tip muffler configuration. This is the louder, more race-inspired option for the FL5, more exhaust presence under load, a crisper response to throttle inputs, and a tone that reflects the Type R’s intent rather than softening it. Triple burnt titanium tips. Front pipe included.

The R400 muffler design foregoes the resonated baffle arrangement of the Q300 in favor of a freer-flowing configuration that prioritizes exhaust gas exit speed. At WOT the FL5 sounds serious through the R400, turbo spool and blow-off are clearly audible, the exhaust note builds aggressively with RPM. The single-layer tip construction keeps system weight lower than double-wall alternatives.

The front pipe included in this kit addresses the restriction between the turbocharger and the cat-back, on the FL5, the front pipe replacement contributes more to throttle response improvement than any cat-back change alone. Full bolt-on installation at OEM flange connections.

Why Choose Invidia

Invidia has been manufacturing performance exhaust systems in Japan since 1999, and in that time they have built a reputation that carries real weight in the tuning community. Every system is manufactured using SUS304 stainless steel and mandrel-bent tubing, which eliminates the flow restrictions and weak points that crush-bent alternatives introduce at every corner. Their in-house engineering team designs each application from scratch rather than adapting a generic template, which is why Invidia fitment is consistently tighter than the competition. The result is an exhaust that installs cleanly, seals correctly, and lasts. Invidia backs their products with a quality standard that is visible in the finish, the weld quality, and the hardware, details that reflect over two decades of refining the same core manufacturing process.

The RallySport Take

We carry the R400 Gemini for the FL5 for customers who already know they want the aggressive option. If you are comparing it to the Q300, the honest difference is sound level and intent, the Q300 is the daily driver, the R400 Gemini is the car that announces itself. The front pipe inclusion makes this a more complete package than a cat-back alone. This fits the 2023-2026 Honda Civic Type R FL5. If you drive this car hard and want people to know it, this is the exhaust.
