Lexus GX 460 Exhaust System Service Malaysia
GX 460 has a stainless steel exhaust system with 4 catalytic converters (2 front + 2 rear). Inspect hangers and flex sections at every major service. The V8 exhaust runs hot — inspect manifold gaskets for leaks at 100,000 km. Aftermarket performance exhausts are available but emissions compliance must be maintained.
Lexus GX 460 Exhaust System
- GX 460 V6 exhaust: body-on-frame truck — exhaust routing passes near frame and skid plates; inspect for contact points when off-roading
- Off-road exhaust damage: rock strikes can dent or crack exhaust pipes — inspect after every serious off-road run
- GX exhaust heat shields: more extensive underbody protection than road cars — still check that heat shields are secure after off-road use
- Exhaust manifold gaskets (1GR-FE): inspect at 100,000 km — manifold gasket failure causes ticking noise on cold start and slight power loss
