Futaba Industrial Exhaust System Adopted for Nissan Elgrand

Futaba Industrial Exhaust System Adopted for Nissan Elgrand

Futaba Industrial Co., Ltd. has announced that its exhaust system has been adopted for Nissan’s all-new Elgrand. Compared with the exhaust system used in the previous model, the new design uses a simplified structure with fewer components and reduced weight. The development focuses on improving the internal configuration of the center muffler while maintaining its acoustic performance. The adoption strengthens the role of Futaba Industrial Co Ltd in supplying optimized exhaust-system components for passenger vehicles while addressing requirements for lighter and more efficient vehicle structures.

Optimized Center Muffler Reduces Components

In the center muffler, the positions of holes in the internal pipes were optimized to create an exhaust flow that reduces deformation of the muffler shell while maintaining acoustic performance. This internal-flow approach allowed the number of separators, or partition plates, to be reduced from five to three. The change simplifies the muffler structure without compromising the stated acoustic objective. The revised design contributes directly to component reduction and supports the overall weight-saving objective of the exhaust system adopted for the all-new Nissan Motor Co Ltd Elgrand.

Internal Valve Eliminated to Further Reduce Weight

The new exhaust system also eliminates the internal valve that was previously used for noise reduction. Removing this component further reduces the system’s weight while simplifying its overall configuration. Together with the reduction in separators from five to three, the change demonstrates how internal exhaust-flow optimization can support component reduction without changing the stated acoustic-performance objective. For Futaba Industrial Co Ltd, the Nissan Elgrand application highlights an engineering approach focused on reducing parts and mass while retaining the required functional performance of the exhaust system.

Frequently Asked Questions

What changes were made to the Nissan Elgrand exhaust system?
The exhaust system adopted for the all-new Nissan Elgrand uses a simplified structure with fewer parts and reduced weight compared with the previous model. In the center muffler, optimized hole positions in the internal pipes create an exhaust flow designed to reduce shell deformation while maintaining acoustic performance. This allowed the number of separators to fall from five to three. The previously used internal valve for noise reduction was also eliminated, providing an additional weight reduction. These changes collectively simplify the exhaust system while retaining its stated acoustic-performance requirements.
