FAQs
What Are the Signs of a Failing Truck Exhaust?
Common signs include loud engine noise, poor acceleration, increased fuel consumption, rattling sounds, and visible damage or leaks in the exhaust pipes. These issues can worsen if left unrepaired.
Is It OK to Drive With an Exhaust Leak?
No. Exhaust leaks can let toxic fumes enter the cab and reduce engine performance. Driving with a leak can also cause further damage to downstream components like the DPF or sensors.
