Description
There’s nothing worse than spending long hours on your David Brown with an exhaust system that’s rattling, leaking, or just plain missing pieces. A worn exhaust isn’t just annoying – it’s robbing you of power, making every workday a test of your hearing, and potentially letting fumes into your workspace. This complete exhaust system transforms your 880 3-cylinder or late 990 Selectamatic back to the smooth, civilized operation these British tractors were designed for.
What You’re Getting
- Complete 3-piece system with 230mm bottom pipe, 635mm silencer, and 200mm top section saves you from hunting down individual components
- Extra-long 635mm silencer box provides superior noise reduction – you’ll actually be able to hear yourself think again
- Dual diameter design transitions from 70mm bottom inlet to 47.5mm top outlet for optimal exhaust flow without restrictions
- Black enamel coating handles exhaust heat without burning off or looking shabby after a season
- Engineered specifically for 3-cylinder 880 and late Selectamatic 990 models – no guessing about fit
Built for British Tractor Work
Your David Brown 880 or 990 Selectamatic represents solid British engineering – compact, reliable tractors perfect for mixed farming operations where versatility matters. Whether you’re running a hay tedder all afternoon, powering equipment during harvest, or handling daily chores with your loader, these tractors work hard. The original exhausts on these vintage machines eventually rust through from decades of heat cycles, creating noise levels that make long days unbearable.
Made to Last
That transition from 70mm inlet to 47.5mm outlet isn’t arbitrary – it’s carefully engineered to maintain proper exhaust velocity while maximizing silencing effectiveness. The long 635mm silencer box uses internal baffles to cut noise without restricting flow, and the black enamel finish resists the high temperatures that cause ordinary paint to fail and flake off.
Installation Notes
This system fits David Brown 880 3-cylinder models and late-production 990 Selectamatic tractors – verify your inlet diameter as early 990s may differ. Remove your old exhaust when cool and use penetrating oil on stubborn clamps and mounting hardware. Install from the bottom up, supporting that heavy silencer box during installation to prevent stress on the pipes. Most folks complete the job in 1.5 to 2 hours and are amazed at how much quieter their David Brown becomes.
