Lexus LS 460/500h Exhaust System Service Malaysia
LS exhaust is stainless steel and durable. The LS 460 V8 has 4 catalytic converters (2 manifold + 2 under-floor). Inspect flex sections and hangers at major service. LS 500h exhaust runs cooler due to EV operation, extending component life. Full exhaust failure before 200,000 km is uncommon.
Lexus LS Exhaust System
- LS exhaust: long wheelbase means extended exhaust run with multiple hangers — inspect all hangers at 80,000 km
- LS 460 V8 exhaust note: V8 has a distinctive sound — any change in exhaust character (louder, rougher) warrants inspection
- LS 500h exhaust: hybrid system means frequent engine stop/start — exhaust sees more thermal cycles; flex pipe inspection at 80,000 km
- LS exhaust catalyst: LS has pre-catalysts near manifold plus main catalysts — any catalyst fault triggers check engine light; scan before replacing
