Invidia 2017 Honda Civic Type-R Gemini/R400 Full 76mm Exhaust w/Front Pipe and Titanium Tips
The Invidia Gemini/R400 Full 76mm Exhaust System with Front Pipe and Titanium Tips establishes the benchmark for high-flow performance in 2017–2021 Honda Civic Type R FK8 models, delivering unrestricted exhaust scavenging and a refined aggressive tone that outperforms restrictive OEM configurations or basic cat-back setups through mandrel-bent S304 stainless steel piping and independent muffler resonators. Featuring a complete 3-inch (76mm) diameter layout from downpipe connection to triple burnt titanium outlets, this system maximizes horsepower and torque gains while minimizing backpressure for quicker throttle response and deeper mid-range pull during track sessions or canyon carving, all without the drone or rasp common in less refined alternatives. The R400 tuned mufflers with Advantex packing balance volume and resonance for a sporty note that enhances the 2.0T engine's character, while the included 3-inch front pipe ensures seamless integration and optimized flow from the primary cat. Built with 1.5mm thick walls, cast flanges, and robot TIG welds for vibration-free durability, this bolt-on assembly offers enthusiasts a lightweight, corrosion-resistant upgrade that supports up to 20+ hp increases when paired with tuning, providing superior heat management and longevity compared to piecing together individual components from various sources.
