DINEX Exhaust Pipe with Bellow for Volvo Trucks. This direct-replacement exhaust stack component is engineered to restore the exhaust flow path and the flexible connection between fixed piping and the vertical stack on Volvo on-highway trucks. The assembly is manufactured to match OE fit and connections referenced to Volvo OE numbers 22563156 and 23790336, and is supplied as a complete pipe-and-bellow kit with necessary clamps and gaskets. Construction uses corrosion-resistant 409 stainless steel and the design meets EPA17 emissions-series requirements, enabling fleets to maintain certified exhaust routing and aftertreatment integrity. Installing this Dinex pipe and bellow re-establishes a sealed exhaust run where a cracked pipe, failed weld, or fatigued flex joint has caused leaks, unmetered exhaust loss, or abnormal backpressure. Because it is a direct-fit replacement it removes the need for time-consuming field modifications and reduces labor hours on repair events. The kitized format—pipe, flexible bellow, clamps and gaskets—streamlines parts procurement and on-vehicle replacement, shortening repair turnaround and supporting faster return-to-service. For maintenance planners and shop supervisors, this part provides a documented OE-referenced option that preserves exhaust geometry and supports continued operation of aftertreatment systems under EPA17 requirements. The product is offered with manufacturer-specified quality controls and a limited warranty, and is distributed ready for installation to minimize fleet downtime during exhaust repairs.
