Stainless Works HCA32.5 Header Collector Adapter 3-Bolt 3" x 2-1/2" 304 Stainless

The Stainless Works HCA32.5 is a precision-crafted header collector adapter designed to connect a 3-inch, 3-bolt header collector flange to a 2-1/2-inch OD exhaust outlet. Built from 304 stainless steel, this adapter delivers exceptional corrosion resistance and long-lasting durability in demanding high-heat exhaust environments.

Key Features:

• 304 stainless steel construction for maximum corrosion and heat resistance
• TIG welded throughout for superior strength and leak-free joints
• 3-bolt flange inlet — 3-inch diameter to mate directly to standard 3-bolt header collectors
• 2-1/2-inch OD outlet for connection to downstream exhaust tubing
• 6-inch overall length for proper adapter geometry and flow transition
• 3/8-inch thick laser-cut flanges for precise fit and a rigid, rattle-free seal
• Mill finish — natural stainless appearance
• Made in the USA by Stainless Works
• Backed by a limited lifetime warranty

This exhaust header reducer is a universal-fit component ideal for custom exhaust builds, header installations, and performance exhaust fabrication projects where a 3-inch collector must transition to 2-1/2-inch exhaust tubing. Sold individually.
