Does the Toyota Aurion's catalytic converter need replacing at high kilometres?
Catalytic converters can degrade over time, particularly at very high mileage, showing symptoms like reduced power, a rattling noise or a failed emissions test. A standard replacement converter restores factory-spec performance.
Is a performance exhaust legal on a Toyota Aurion?
A cat-back performance exhaust that retains the factory catalytic converter generally maintains emissions compliance, though overall noise still needs to meet your state's road rules.
Will a performance exhaust make a noticeable sound difference on the Aurion's V6?
Yes, most owners notice a deeper, more resonant tone from the V6 with a performance muffler or cat-back system, particularly under acceleration.
Can I fit a replacement muffler to my Aurion myself?
Some owners fit a direct-fit replacement muffler themselves with basic tools, but professional fitting is recommended to ensure correct clamping, alignment and clearance.
