Restore the integrity of your emissions system with the Exhaust Bellows Kit by Automann. Specifically engineered for EPA17 and EPA21 compliant Mack MP7/MP8 and Volvo D11/D13 engines, this premium bellows assembly connects the turbocharger to the aftertreatment system. A leaking or cracked bellows can lead to lost boost pressure, soot buildup in the engine bay, and failed DPF regenerations; this kit provides a high-performance, leak-proof solution to keep your truck running efficiently.

Advanced 3-Layer Construction: The Exhaust Bellows Kit Advantage

The Exhaust Bellows Kit (Automann Part # 820.B62373P) is built to "Fleet Premium" standards, far exceeding basic aftermarket alternatives. The bellows body features a specialized 3-layer design: a 309 stainless steel outer weave for structural support, a flexible leak-proof core to dampen engine vibration, and an inner interlock layer to maintain smooth, high-velocity exhaust flow. Note: To handle the extreme temperatures of modern SCR and DPF systems, it is encased in a 304 stainless steel reinforced heat insulation sleeve, ensuring nearby components are protected from radiant heat.
