The Tall Stack with That Sharp Mitre Cut Edge This 60-inch (1525mm) Mitre Cut stack gives you serious height with that aggressive 45-degree angle cut at the top that creates a visually striking and assertive appearance. The 8-inch non-reduced diameter runs consistent from bottom to top, giving your diesel engine the breathing room it needs without any flow restrictions. If you’re running a high-roof cab or just want that taller profile with a sharp edge, those extra 12 inches over a standard 48-inch stack make a real difference. The Mitre Cut design isn’t subtle—it’s built for trucks that want to stand out. That diagonal cut creates a classic big-rig silhouette with a sharper profile that breaks up the vertical lines and adds dimension to your truck’s appearance. The 45-degree angle directs exhaust flow upward and slightly back, making it a functional choice beyond just visual appeal.
