Exhaust Service Tips • Use “Wide-Band” style clamps instead of U-Bolt style clamps when installing replacement components. The resulting joint will be leak tight and more easily serviceable on future jobs. “Wide-Band” clamps provide the user full wrap around installation, no pipe distortion when sealing and minimises exhaust leaks and eliminates the need for welding. • Eliminate the exhaust system as a source of cab noise by isolating pipe and mufflers with flexible hangers and brackets. On installations where isolation mounts are not practical, use double wrapped mufflers. • Exhaust gases are passed through the muffler to reduce the noise of engine combustion. At the same time, back pressure causes exhaust gases to remain in the engine cylinder after the exhaust stroke. And, while a certain amount of backpressure is vital to optimal performance, too much can result in loss of horsepower and excessive engine / turbo charger operating temperatures. When this occurs, performance and fuel economy can suffer. • Remember to always replace components with like components in the exhaust system. By replacing an exhaust system part with a like component, you can be assured of the most efficient performance on your engine. • Contact our Customer Assistance team for any exhaust queries that you have on 1800 032 037 (Australia) or 0800 448 363 (NZ). There are five major sources that contribute to the noise level of a highway. 1. Fan Noise – Excessive fan speed is the biggest noise source in this area. This can be controlled by the use of a temperature controlled or thermostatic fan. Other noise concerns are bent fan blades and broken or missing shrouds. 2. Air Intake – Both the type of system and the location of the inlet affect the truck noise level. Air inlets that open to the side are generally noisier than those that do not. 3. Mechanical Noise – The engine and drive train are the major source of noise. Operating speed, type of engine and drive train all affect the total noise level. Shielding the exposed areas with acoustic barriers will reduce noise levels. Generally, any part of the engine or drive train that can be seen while standing away from the truck will contribute toward the total vehicle noise level. 4. Tyres – Many times this is the major noise source at high speeds. The condition of the tyres and the tread pattern affect the noise level. At low speeds this is not a large noise source. 5. Exhaust System – Worn or inadequate exhaust systems are the largest and the most frequent contributor to high noise levels. A visual inspection and repair of leaking connections or replacement of failed components will noticeably reduce noise levels. If the noise level is still too high, the addition of resonators, packed stacks or a change in mufflers is recommended. The muffler application and performance section of this catalog will give you the recommended mufflers for your particular engine and system configuration. Reducing Noise Levels SPECIFIC WAYS TO REDUCE EXHAUST NOISE LEVELS 1 . Worn or leaking flexible tubing is a common noise source. Replace the part if necessary. The service life of flexible tubing can be improved if it is installed in a relaxed position. Bending, stretching and compressing all reduce life because they limit the tubing’s ability to “flex”. 2. The entire exhaust system should be well supported. This will reduce the noise generated by the exhaust pipes and the muffler shell. Care must be taken to isolate engine vibration from the exhaust system and to provide for expansion when the system is hot. 3. The addition of an universal resonator in the system will generally reduce the exhaust noise level from 3 to 6 dBA. Packed stacks would reduce the noise level 3 to 4 dBA. Both items have a minimal effect on engine backpressure. 4. Change from a single to a dual system. For maximum benefit, special “dual only” mufflers are usually recommended. Lower system backpressure is generally an additional benefit of dual systems. 5. On horizontal systems, the tail spouts should be pointed towards the center of the roadway. This reduces the noise reflected off the road surface and perceived by kerbside observers to be quieter. 6. On vertical systems, straight stacks will yield lower sound levels than will curved stacks. Straight stacks direct the noise upward, where curved stacks direct noise towards the observer. US FEDERAL NOISE ACT 1978 EXHAUST NOISE LEVEL IN dBA Excellent Good Marginal 66 68 70 72 74 76 78 80 82 Exhaust noise levels less than 73 will allow almost any truck to meet an 83 dBA level. The only exception is a vehicle with several other excessive noise sources. Exhaust noise levels between 73 and 78 dBA would enable a vehicle to meet an 83 dBA level if the other noise sources are normal. Exhaust noise levels of 78 dBA or higher generally will not allow a truck to have a total vehicle noise of 83 dBA unless all other noise sources are controlled. To reduce the vehicle noise level to 80 dBA, the categories on the chart must be reduced 4 dBA. Excellent would be less than 69 to 74 dBA and marginal would be 74 and above.
