American BOA engine exhaust manifolds and system components are designed to reduce engine downtime, improve engine efficiency and to provide increased engine reliability. Most manifolds are designed as modular systems connected by flanged expansion joints. The modular system provides for easy handling, easy installation and easy removal for routine engine maintenance. BOA's multiply bellows design provides maximum flexibility with minimum spring forces. The multiply bellows utilized dampens vibration, thereby lowering bolt and turbocharger stresses and minimizes system fatigue.

We are routinely involved in customer projects with the goal of decreasing cost via a more efficient system design. Our approach is to review the entire system, not just one component such as the expansion joints, and eliminate unnecessary materials with more technically advanced solutions that prove over the long term to be more cost effective. Each solution recommended is backed by detailed analysis and critical stress evaluations.
