Lexus RX 270/350/450h Exhaust System Service Malaysia
RX V6 exhaust is stainless steel and durable. Inspect hangers and connections at major service. Common wear point: exhaust front pipe flex section (between manifold and cat) at 100,000+ km — RX 450h exhaust runs cooler due to frequent electric operation. Full cat-back replacement rarely needed before 200,000 km.

Lexus RX Exhaust System
- RX V6 exhaust: dual exit exhaust on V6 models — both tips should emit equally; uneven flow suggests an exhaust restriction
- RX exhaust hangers: heavy SUV body — exhaust hangers endure more stress; inspect for cracking at 80,000 km
- RX muffler: inspect rear muffler for internal baffle failure if you hear increased exhaust volume — common beyond 150,000 km
- RX 450h exhaust: hybrid system means engine shuts off at low speed — exhaust cools and reheats more often; inspect flex sections more regularly
