The Invidia Q300 Axle-Back with titanium tips for the 2014-2015 Lexus IS250 and IS350 delivers Q300 sound refinement on the third-generation IS sedan. The Q300’s resonated design produces a deeper, more refined sound than the factory exhaust while maintaining the IS’s luxury-sport character. Titanium burnt tips.
DETAILS
- Axle-back muffler replacement
- Burnt titanium tips
- Q300 resonated muffler
- 304 stainless
The 3rd-gen IS uses a rear dual-exit layout that the Q300 axle-back replaces cleanly at the factory mid-pipe flange. The resonated Q300 design prevents the hollow sound that some aftermarket axle-backs produce on V6 applications.
Titanium burnt tips on the IS250/IS350 are a premium upgrade matching the car’s luxury sport positioning.

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.
