Invidia R400 Rolled Titanium Tip Cat-Back – 2023-2026 Toyota GR Corolla

R400 Rolled Titanium Tip Cat-Back for the 2023-2026 Toyota GR Corolla

The Invidia R400 Cat-Back with rolled titanium tips for the 2023-2026 Toyota GR Corolla steps up to the R400’s more aggressive muffler configuration on the GR4 platform. The R400 is tuned for more exhaust presence, louder under load, more responsive to throttle inputs, with the G16E-GTS three-cylinder character coming through more clearly than the Q300 allows. Rolled titanium tips.

The R400 muffler configuration produces a more aggressive sound character than the Q300 at all throttle positions. On the GR Corolla’s G16E-GTS three-cylinder, the R400 sound is distinctive, a combination of the engine’s natural three-cylinder exhaust pulse and the R400’s free-flowing exit. The rolled titanium tips add visual quality to the rear.

304 stainless mandrel-bent piping throughout ensures consistent wall thickness at every bend. The R400 is the middle ground between Q300 refinement and full titanium premium construction, maximum sound from a stainless system for the GR Corolla.

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 R400 is for GR Corolla owners who want the exhaust to match the car’s character. The three-cylinder G16E-GTS has a personality all its own and the R400 lets that personality express itself through the exhaust in a way the Q300 does not. If you are building the GR Corolla toward more aggressive performance use, track days, canyon driving, the R400 is the correct choice. Fits the 2023-2026 GR Corolla GR4.
