Stainless Works HCA3.52.5 Collector Adapter 3 Bolt 3-1/2" to 2-1/2"

The Stainless Works HCA3.52.5 is a precision-engineered collector adapter designed to transition from a 3-1/2" three-bolt collector flange to a 2-1/2" outlet diameter. Constructed from premium 304 stainless steel, this adapter provides exceptional corrosion resistance and long-lasting durability in high-temperature exhaust environments.

Key Features:

• Premium 304 stainless steel construction for maximum corrosion resistance
• TIG welded for superior strength and leak-free performance
• 3-1/2" three-bolt collector flange inlet
• 2-1/2" OD (outside diameter) outlet
• Precision-formed for optimal exhaust flow
• Proudly made in the USA
• Backed by limited lifetime warranty

This collector adapter is ideal for custom exhaust fabrication or header installations where you need to reduce from a larger collector to smaller exhaust tubing. The three-bolt flange design ensures a secure, gasket-sealed connection that can withstand the thermal cycling and vibration inherent in performance exhaust systems.
