What happens to fuel when exhaust pipe has holes?
Hello - holes in the exhaust will not affect fuel flowing into the engine. however, the exhaust gases, which should be close to completely burned at the point they flow through the muffler/silencer, have high levels of carbon monoxide. This is dangerous to passengers, and can be sucked into the passenger compartment. This is why it is important to have a complete exhaust system that routes these gases to the rear bumper area. If there is any doubt as to this being an issue, I would highly recommend having your exhaust system inspected, by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for safe repairs.
