Xoepoll 3" Exhaust Flange Adapter - T304 Stainless Steel 2-Bolt, 3" OD Repair Flange

The Xoepoll 3" T304 stainless steel 2-bolt exhaust flange adapter is a universal header collector flange designed to replace damaged flange connections and restore a sealed 3-inch exhaust join.

This adapter is a compact, weldable repair piece made from T304 stainless steel for corrosion resistance and heat tolerance. It fits a wide range of cars, trucks, SUVs and light-duty exhaust systems where a 3-inch outer diameter header collector or pipe-to-flange connection needs replacement. The flange features two bolt holes and is offered as a straightforward, serviceable component for exhaust maintenance and fabrication projects.

How does this flange adapter restore a leaking or broken exhaust connection?

It replaces the worn or rusted collector flange and provides a flat, weldable surface to reconnect the exhaust piping. Because it has a 3" outside diameter and two bolt holes, it aligns with many standard 2-bolt exhaust patterns to recreate a sealed joint.

• Direct-fit 3" outside diameter for common collector pipes
• Two-bolt pattern supports standard gasketed connections
• T304 stainless resists corrosion so the repair lasts longer
• Weldable edges allow secure, permanent installation

What materials and build quality can I expect from this replacement flange?

The adapter is fabricated from T304 stainless steel, chosen for its balance of strength and oxidation resistance in typical exhaust temperatures. The metal is formed to provide a flat mating surface and rigid bolt ears for dependable clamping of a gasket and exhaust tubing.

• Premium T304 grade stainless steel construction
• Heat-tolerant, corrosion-resistant finish for harsh conditions
• Precision-formed bolt ears to minimize warping during tightening
• Designed to resist cracking or deforming under normal exhaust loads

How do I install the Xoepoll 3" two-hole flange adapter?

Installation options include welding the adapter onto a pipe or using bolts with a compatible gasket to join two flanged surfaces. The part is intended as a quick repair or as a component in custom exhaust fabrication; no gasket is included, so plan to source the correct gasket and hardware for your vehicle.

• Clean mating surfaces and align bolt holes before fastening
• Weld the adapter for a permanent, leak-free repair if desired
• Use a proper 2-bolt exhaust gasket and high-temp bolts for bolted joins
• Verify 3" OD compatibility with your existing collector or pipe

Will this flange fit my vehicle’s exhaust system?

It is a universal-style adapter designed to work with many 3" OD exhaust collectors and pipes on cars, light trucks and SUVs. Confirm measurements and bolt-hole spacing on your existing flange or pipe before purchasing to ensure correct fitment.

• Intended for 3" outside diameter header/collector pipes
• Two-hole configuration suits common 2-bolt exhaust layouts
• Suitable for repairs and small fabrication jobs on most light-duty vehicles
• Measure your pipe and bolt pattern to guarantee compatibility

Who is this for: The Xoepoll 3" T304 two-bolt exhaust flange adapter is ideal for DIY mechanics, exhaust repair shops and fabricators who need a durable, weldable replacement flange for 3" collector pipes. It’s useful when an original flange is corroded, cracked or missing—providing a cost-effective way to rebuild or reroute an exhaust connection with stainless-steel longevity. Note that the product does not include a gasket, so plan to acquire the correct gasket and fastening hardware for a complete installation.
