8" Stainless Steel 90 Degree Elbow 17" - 10"

The Reducer Elbow That Actually Works

This 90-degree reducer elbow does two jobs at once—it changes your exhaust direction by 90 degrees while smoothly stepping down from 8-inch diameter to 5-inch. If you’re routing exhaust around frame rails, chassis components, or tight spaces, this elbow gives you the flexibility you need without creating flow problems.

The dimensions matter here: Length A measures 17 inches (430mm) and Length B comes in at 10 inches (254mm). These aren’t random numbers—they’re sized to navigate around common truck chassis obstacles while maintaining proper exhaust flow. The longer leg gives you room to work with, while the shorter leg keeps things compact where space is tight.
