• Construction: Concentric reducer design with smooth tapered transition from 5-inch ID to 4-inch ID providing optimal exhaust flow with minimal back pressure.​
• Material: Heavy-gauge aluminized steel construction offering superior corrosion resistance and extended service life in harsh exhaust environments.​
• Design: Engineered with precision-formed tapered walls ensuring leak-free connections and proper fitment with standard exhaust components.​
• Application: Universal design suitable for connecting larger exhaust pipes to smaller diameter components including mufflers, catalytic converters, and tailpipes in automotive and commercial applications.

This is a universal exhaust reducer/expander featuring a 6-inch overall length with 5-inch inside diameter inlet tapering to 4-inch inside diameter outlet. The aluminized steel construction provides excellent corrosion resistance while the smooth internal transition maintains optimal exhaust flow characteristics. Designed for slip-fit installation with standard exhaust clamps.
