A typical automotive exhaust system runs very hot and encounters an extremely corrosive and hostile environment. In addition, the range of motion between a softly mounted engine and exhaust pipe can be dramatic, especially with very little package room. Engineering a flexible exhaust connector demands careful attention to engine and chassis dynamics to ensure life-long durability. We have engineered thousands of automotive flex pipes to ensure life-long durability. The exhaust connector provides a leak-free connection, meeting new emissions standards, absorb engine rocking motions, and isolate vibration from the rest of the exhaust system, so passengers do not experience poor NVH.
