The Invidia Q300 Catback Exhaust is the go-to system for enthusiasts seeking a perfect blend of power, refined sound, and daily drivability. Unlike its louder N1 counterpart, the Q300 is designed with a more mature tone, using advanced muffler technology to deliver performance gains without attracting unwanted attention. It’s the exhaust system that transforms your car without turning every drive into a shouting match with your engine.

Crafted from high-grade SUS304 stainless steel with mandrel bends and CNC-machined flanges, the Q300 offers a direct bolt-on fit with exceptional durability and corrosion resistance. The design features Advanced mufflers with multi-chamber internal baffling, carefully engineered to reduce drone and harshness while enhancing low-end and mid-range torque. The result is a deep, refined exhaust note under acceleration that remains quiet and comfortable at cruise—ideal for performance cars that see both street and highway use.

We typically recommend the Invidia Q300 exhaust for enthusiasts seeking only an incremental volume increase over their OEM exhaust, focusing more on enhancing tone and introducing a mature sound to their build.

This system utilizes robotic TIG welding and polished rolled tips (in single or quad-exit configurations depending on the vehicle), giving your build a clean, premium appearance. Whether naturally aspirated or turbocharged, the Q300 provides consistent, dyno-proven power gains with OEM-like fitment. It’s the perfect solution for those who want all the performance benefits of a free-flowing catback system—without the noise penalty.
