Invidia Q300 Axle Back Exhaust – 2006-2012 Lexus IS 250/350

Q300 Axle-Back Exhaust for the 2006-2012 Lexus IS250 and IS350

The Invidia Q300 Axle-Back for the 2006-2012 Lexus IS250 and IS350 delivers Q300 sound refinement on the second-generation IS platform. Axle-back scope replaces only the rear muffler section, preserving the factory mid-pipe and catalytic systems. The Q300’s resonated design produces a deeper, more defined note appropriate for a Lexus luxury sport sedan.

DETAILS

• Axle-back muffler replacement
• Q300 resonated muffler
• 304 stainless

The 2nd-gen IS250 and IS350 use the 4GR-FSE V6 and 2GR-FSE V6 respectively, both naturally aspirated engines with a refined character that the Q300 enhances correctly. The axle-back is the correct scope for an IS owner who wants a sound upgrade without a full system change.

Bolt-on connection at the factory mid-pipe flange makes installation straightforward. The Q300 sound is subtle enough to be appropriate for the IS’s Lexus 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.
