Stainless Steel Exhaust Flange 3-Bolt 3.0" 76mm 0.5" Thick Downpipe Catback

Stainless Steel 3-Bolt Exhaust Flange 3.0" 76mm 0.5" Thick

This stainless steel exhaust flange is a 3-bolt, 3.0-inch (76mm) unit with a 0.5-inch thick mounting plate, built to create a secure, gasket-ready joint between downpipe and catback sections on custom or repaired exhaust systems.

Overview

The 3-bolt exhaust flange connects pipe sections at the downpipe, catback, or mid-pipe joint and compresses a gasket for a sealed, serviceable union. With a 76mm opening and a 0.5-inch thick plate, this flange suits builders doing custom exhaust work and drivers replacing a rusted or cracked factory flange for a durable stainless alternative.

Built For Performance

• Stainless steel construction resists corrosion and heat cycling better than mild steel
• 0.5-inch thick flange plate resists warping under exhaust heat and bolt torque
• 3-bolt pattern aligns with common gasket and pipe layouts
• 3.0-inch (76mm) center opening matches standard 3-inch exhaust tubing
• Machined mating face supports clean gasket sealing

On-The-Job Use

• Joining downpipe to catback sections on custom exhaust builds
• Replacing a warped or rusted factory flange during exhaust repair
• Building serviceable slip-and-bolt joints for turbo or performance exhausts
• Weld-on fabrication work for DIY and shop exhaust projects

Specs At A Glance

Good To Know

Q: Is this flange a bolt-on replacement? A: It depends on your existing pipe layout, since a flange of this type is typically welded to the pipe end before bolting to the mating section. Confirm the weld-on end fits your tubing size before ordering.

Q: Are bolts and a gasket included? A: Hardware and gaskets are usually sold separately with flanges of this kind. Check the listing contents to confirm what ships with the flange.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
