The Audi R8 exhaust system has the important task of directing and expulsion of flue gasses from the engine out the exhaust pipe. Sometimes restrictions block the flow of flue gasses and cause leakage. Sometimes the pipes of the exhaust system components and their connections can loosen, which can cause leaks that can be seen and heard. The exhaust system begins by the exhaust manifold and terminating in the exhaust pipe. Everything between the front and rear exhaust pipe can check for leaks and repair.
Audi R8 Exhaust System-Manifolds
The Board exhaust manifold takes a lot of punishment in the form of expansion and contraction. The board may fail due to the stresses and pressures must support and gives warning signs. Whistling or popping noises from the collector indicate a possible leak. No black soot around the collector surface to the coupling head indicates that the exhaust gasses. Look melted cables, where excessive heat has caused burning. Another indicator will be the release of carbon monoxide entering the passenger compartment. Carbon monoxide gas can cause dizziness, nausea, and confusion. Cracked exhaust manifolds can emit noises or sounds “slapping,” sometimes at a very low frequency.
Tube Collector Header
The manifold for connecting header pipe usually has a large graphite board or flange bearings and metal-making. Front-wheel drive vehicles, this joint has much bending movement of the motor during displacement and hard acceleration, causing the joint to flex and wear. The output of this joint assembly will often cause very strong rumbling sounds and the smell of burning fuel. Sometimes it can emit black smoke this joint. Any discoloration in this joint as the accumulation of black carbon or soot streaks point to a poor collector to the junction of the header pipe. Again, carbon monoxide is a real danger in this area.
The new catalytic converter is burning excess fuel that has come from the combustion chamber by using extreme heat and a chemical reaction. If heated too fading into the outer casing (shields below) showing a colorful rainbow pattern, a sign that burned internally. Chemical pills inside the converter will give a rotten egg smell when the engine has warmed up. A clogged or saturated converter will create enormous pressure that sends exhaust gas back and out through points of least resistance as multiple common headers or exhaust manifold gasket. A bad catalytic converter must be replaced immediately.
Mufflers And Resonators
Mufflers and resonators dampen exhaust noise and are midway mounted under the chassis or the end near the exhaust pipe. Collect the most water condensation and can rust from the inside out. Sometimes the drainage holes can be seen in their boxes at the bottom. Rusty water drips out of the drainage holes indicates the inner oxidation, where the baffle plates have deteriorated. Mufflers and resonators typically mold from the bottom. So any scales or rotten metal indicates a partial or total failure of the inner structure and a leak can be expected in this area before too long.
Component Tubes And Joints
Anywhere in the Audi R8 exhaust system which couples a muffler clamp tube, catalytic converter or resonator can weaken and break. The joints will first mechanically seal or welded. Other locations include suspected leak areas where there are any bends in the tube as the loop on the shaft. Pipe hangers and muffler can be released and let the gas escape fall, shock, and other chassis parts, eventually causing mechanical abrasion damage.
