Backpressure A key performance factor in selecting the proper muffler is backpressure. For the most efficient engine performance it is important to apply a muffler that minimizes backpressure. Backpressure is the force necessary to flow gasses through the Exhaust system, or the resistance to exhaust flow. System considerations include friction and momentum effects - expansion / contraction / elbows, and velocity head loss at outlet. To minimize backpressure, long tube lengths, …

Bent Tubes & Elbows For directional changes of exhaust flow in exhaust systems. Available in common angles (90°, 67° and 45°) for both O.D. andWye Connector For joining legs of dual manifold outlet to form a single exhaust system. Wye connectors can provide an additional 3 to 7 dBA exhaust noise reduction over that of the primary muffler and may also be used to replace conventional wye pipe.Resonator Secondary noise reduction component that generally provides 2 to 3 dbA addition …

Easy Maintenance Tips Reduce Exhaust Noise  1. Check the exhaust tubing. Repair or replace worn or leaking components.  2. Make sure your exhaust system is properly supported.  3. Installing a resonator or wye connector muffler is an economical way to reduce noise.  4. Modify a single exhaust system to a dual.  5. Check stack and tailpipe position. A straight stack will be quieter than a curved stack on vertical exhaust systems. Turn your horizontal tailpi …

409 Stainless is a softer form of 304. It IS magnetic, but still retains some anti-rusting materials. Normally used in after market exhaust systems from the "BIG GUYS", 409 stainless is the best for exhaust. It bends just as easy as steel and aluminized with the same "springback" as those materials. It looks great, welds great and is highly under rated in the aftermarket "builds" you see on youtube and other websites. 409 can be welded with a MIG welder or TIG welded for a better look. 409 …

Introduction A system designer must consider environmental and performance criteria when sizing and positioning the exhaust system of a generator set. Correct installation of the exhaust is also crucial to ensuring full performance of the engine. This info sheet is a guide and discusses the issues to be addressed when installing a generator set’s exhaust system. Key purpose of the exhaust system: All engine systems have exhaust systems to facilitate: Safe evacuations of gases - Exhaust …
