Quantum exhaust systems on the 2.5 D-4D and 2.7 VVTi run a relatively simple layout — manifold, front pipe, cat, centre section, and tailbox — without the DPF and SCR complications of newer diesels. Our toyota quantum exhaust range covers exhaust manifolds, catalytic converters, front and rear sections, mufflers, oxygen sensors, and flex pipes. Taxi service creates thermal stress that eventually cracks manifolds and blows flex joints, and we stock both new aftermarket replacements and used OEM pulls.

Catalytic converter theft hit Quantum operators hard between 2020-2024 because these minibuses park in unsecured taxi ranks overnight. Replacement used OEM cats are increasingly scarce — aftermarket direct-fit cats from the JHB depot at R3,500-R8,500 are the practical answer for most fleet operators. Oxygen sensors (upstream and downstream) are common consumables at 120,000-180,000 km, and we stock OEM-quality sensors from R450 each. Flex pipe welds on hard-working Ses'fikiles commonly crack at 200,000 km — cheap repair, important to catch early before the engine bay fills with exhaust gas.

Exhaust for Toyota Quantum — Frequently Asked

My Quantum catalytic converter was stolen — what are my options?

Aftermarket direct-fit catalytic converters for the 2KD-FTV and 2TR-FE Quantum run R3,500-R8,500 from the JHB depot. Used OEM cats are scarce due to widespread theft. Budget for new clamps, a flex-pipe re-weld, and replacement oxygen sensors (the thieves usually cut the wiring). Some operators fit a cat-theft shield at the same job — worthwhile for taxi-rank parking.

How much is an oxygen sensor for a Toyota Quantum?

OEM-quality oxygen sensors for the 2KD-FTV and 2TR-FE run R450-R950 each depending on whether you need the upstream or downstream unit. Genuine Toyota Denso sensors are R950-R1,600. Always replace in pairs if both are from the same service interval — one failing usually means the other is close behind.

Do you stock Quantum exhaust manifolds?

Yes. Used 2KD-FTV exhaust manifolds from CPT-dismantled donors trade R1,400-R2,800 with a standard crack inspection. 2TR-FE petrol manifolds run R1,200-R2,400. New aftermarket manifolds from the JHB depot are R3,200-R5,800. Always replace manifold gaskets and studs rather than reusing them — cheap consumables that prevent repeat labour.
