Exhaust Stack 5in x 8in 36in L Black

The Exhaust Stack 5in x 8in 36in L Black by PYPES Performance Exhaust is a purpose-built vertical exhaust outlet designed for trucks, hot rods, and custom diesel applications where traditional rear-exit configurations won't work. This component serves as the final vertical riser that directs exhaust gases upward and away from the vehicle frame, bodywork, and passengers—critical for vehicles with custom chassis layouts, lifted suspensions, or engine swaps where conventional exit points conflict with structural or aerodynamic requirements. Whether you're building a show truck, restoring a classic with a modern powertrain, or modifying a work vehicle, this exhaust stack provides both functional necessity and distinctive visual presence.

Constructed from heavy-gauge steel with a durable black finish, the 5-inch by 8-inch rectangular profile accommodates dual exhaust systems or high-volume single-outlet configurations typical of turbocharged and naturally aspirated performance engines. The 36-inch length provides sufficient height to clear most custom cab designs, tonneau covers, and bed-mounted accessories while maintaining proper exhaust velocity and scavenging characteristics. PYPES Performance Exhaust engineered this stack with mandrel-bent transitions and reinforced seams to withstand thermal cycling, vibration, and the corrosive environment under a working vehicle—a critical consideration for diesel trucks and vehicles that see frequent use. The rectangular opening accepts standard 5x8-inch elbows and adapters, ensuring straightforward integration into existing or new exhaust systems.

This exhaust stack is essential for diesel truck builders, hot rod shops, and serious off-road enthusiasts who demand exhaust routing flexibility without sacrificing durability or appearance. Installation typically requires welding to secure transition elbows and may involve custom mounting brackets depending on your chassis geometry. Verify compatibility with your specific frame design, bed height, and clearance requirements before purchasing—stack height and position critically affect both performance and safety. At 12.7 pounds, it's lightweight enough for easy installation while maintaining the structural integrity needed for long-term reliability in aggressive driving conditions.
