Description
When that curved section right after your exhaust box starts cracking or rusting through, you’ll hear it before you see it—that telltale popping sound that gets louder with RPMs. This pipe takes the worst abuse in your exhaust system, handling maximum temperatures and pressures right where gases exit the exhaust box and need to change direction without losing flow. A failed curved section doesn’t just make noise—it can direct hot gases toward components that weren’t meant to handle that kind of heat.
What You’re Getting
- Precise curve angle engineered to maintain proper exhaust velocity while clearing engine components
- Heavy-duty construction that handles the extreme thermal stress of this high-temperature position
- Direct replacement design that connects perfectly to your exhaust box outlet
- Quality materials that resist the corrosive exhaust gases these engines produce
Built for Real Farm Work
Your John Deere 6800 or 6900 represents serious horsepower for demanding field operations—whether you’re pulling wide tillage equipment, powering large forage harvesters, or handling heavy transport duties. These high-horsepower machines work hard, and their exhaust systems need to handle the heat and pressure that comes with that kind of power. The curved pipe from the exhaust box is where your exhaust system starts routing those hot gases safely away from critical components.
Made to Last
Located right after the exhaust box, this curved section sees maximum exhaust temperature and pressure—conditions that destroy inferior parts quickly. This replacement is specifically engineered for the higher exhaust volumes and temperatures that bigger John Deere engines produce, with materials that handle extreme heat cycling without cracking or burning out.
Installation Notes
Let the engine cool completely before starting work—this section gets extremely hot during operation. Clean all connection surfaces thoroughly and use new gaskets to ensure leak-free connections at this critical junction. Support the downstream exhaust properly to prevent stress on the curved section, and check clearances to nearby components since heat expansion can cause interference if positioned incorrectly.
