Invidia Q300 Rolled S.S Tip Cat-Back – 2023-2026 Toyota GR Corolla

Q300 Rolled Stainless Steel Tip Cat-Back for the 2023-2026 Toyota GR Corolla

The Invidia Q300 Cat-Back with rolled stainless steel tips for the 2023-2026 Toyota GR Corolla brings Q300 performance and sound refinement to the GR4 platform. The 76mm mandrel-bent stainless piping improves flow over the factory system, the Q300 muffler delivers a deep and refined exhaust note, and the 110mm rolled stainless tips provide a clean classic look at the rear exit.

DETAILS

• Piping diameter: 76mm
• Piping material: 304 stainless steel
• Tip diameter: 110mm rolled stainless steel
• Q300 resonated muffler design
• Mandrel-bent piping throughout
• Direct OEM fitment

The Q300 muffler design uses calibrated resonators to produce a deep tone without excessive cabin drone at highway speeds, a balance that is harder to achieve on a three-cylinder engine because the firing interval creates a more prominent exhaust pulse. Invidia tuned the GR Corolla Q300 specifically for the G16E-GTS’s acoustic characteristics, so the sound is properly matched to the engine.

Rolled stainless steel tips are a clean, timeless look that works with any GR Corolla exterior color. The 110mm diameter is appropriately sized for the platform. Installation is bolt-on to factory 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

The Q300 is the exhaust we recommend for GR Corolla owners who drive the car daily and want the sound upgrade without going aggressive enough to make it tiring. It is also the right call if the full titanium system is outside budget, the Q300 delivers real performance improvement and a noticeably better sound, and the rolled stainless tips look correct on the GR Corolla’s rear. Fits the 2023-2026 GR Corolla GR4 with the G16E-GTS engine.
