Exhaust tips can be lined with sound dampening counsel to decrease the exhaust din.
Your vehicle's exhaust step is designed to not solitary Harbour exhaust gases from the engine to the tailpipe on the contrary besides to compose a scavenging consequence on the gases in the cylinders to advice remove exhaust gases from re-entering the combustion Hospital ward. The muffler on the exhaust contains baffles and chambers designed to dampen the sound produced by the exhaust system. Exhaust tips, while usually designed for visual appeal, can also be designed to alter the sound presence of the exhaust system.
Instructions
1. Turn on the vehicle and drive for approximately 10 minutes to allow the engine, exhaust and catalytic converter to all reach optimal operating temperatures. Park the vehicle with the engine running.
2. Clarify the noise is coming from the exhaust tip. If the sound emanating from the exhaust is produced by a faulty muffler, pipes or catalytic converter, troubleshooting the exhaust tip is not likely to remove the troublesome noise.
3. Hold a screwdriver to the exhaust tip side and press the handle to the side of your head. If there is a loose part in the exhaust tip, you'll hear the clicking sound resonate clearly through the screwdriver. This will indicate loose parts or material which should be removed or secured inside the exhaust tip.
Inspect resonated exhaust tips for damage to the fiberglass or sound-dampening material. Loose material may be causing whistles or chatter in the exhaust tip. Remove loose material or replace the damaged resonated tip.6. If the tip is weld-on, inspect the weld for holes. Seal the exhaust leak with high-temperature RTV silicone, if necessary.
5.4. Turn off the vehicle and inspect the exhaust tip for leaks at the point of seal. Clamp-on and screw-on tips may be allowing exhaust gases to port out the rear of the exhaust tip. Exhaust tips not installed fully over the tailpipe may allow exhaust gases to curl back and escape through the exhaust tip intake (most common when the exhaust tip and the tailpipe do not end at the same point).
Inspect the inside of the exhaust tip with a flashlight for material protruding into the exhaust path. Screws, flaking material or weld material may be jutting into the path of the exhaust and creating a whistling sound or otherwise altering the sound output. If it is a screw jutting into the exhaust path, replace with a smaller screw. For other metal protrusions, use a long file or long-handled screwdriver to bend or remove the material.
7. Inspect the end of the exhaust tip for damage. Small dents, chips or holes in the end of the exhaust tip may create whistling, chirping or rattling (on dual-walled tips).
