EVIL ENERGY 2.5-Inch 2-Bolt Exhaust Flange Kit — 2 PCS 304 Stainless, 64mm ID, Gaskets & M10 Bolts

EVIL ENERGY's 2.5-inch 2-bolt exhaust flange kit is a complete stainless-steel connector set—two flanges, two gaskets and bolts/nuts—designed to create a leak-resistant joint for exhaust, turbo and silencer piping.

This kit is built around a 64 mm (2.52") inner diameter flange made from 304 stainless steel, sized and machined for repeatable fits on 2.5" exhaust systems. It includes precision-cut bolt holes, mating gaskets and M10 x 35 mm bolts and nuts so you can weld the flange to pipe ends and fasten two sections together for a secure, serviceable connection. The flanges are thick enough for welding and include a flange edge to make alignment and welding easier during installation.

How does this flange kit create a tight, leak-resistant connection?

The two mating flange faces clamp together with a gasket sandwiched between them; that gasket compresses to fill surface irregularities and prevent exhaust leaks. CNC-machined bolt holes ensure the bolts pull the flanges into consistent alignment for an even seal.

• Includes two matching gaskets sized for the 64 mm ID flange.
• Precision-drilled bolt holes for accurate alignment and clamping force.
• Use of 304 stainless steel resists rust, maintaining flange flatness over time.

What materials and dimensions should I expect for durability and fit?

The flanges are fabricated from 304 stainless steel, chosen for corrosion resistance and high-temperature stability in exhaust applications. Each flange has a thickness of 10 mm and an inner bore of approximately 2.52" (64 mm), matching standard 2.5" exhaust tubing.

• Flange ID: 2.52" / 64 mm to match 2.5" piping.
• Flange thickness: 0.39" / 10 mm for robust welding and strength.
• Hardware: M10 x 35 mm bolts with compatible nuts included.

How easy is installation and what tools or steps are required?

Installation is straightforward for anyone comfortable with basic exhaust work and welding. Weld the flanges to the pipe ends, position the gaskets between the flanges, then tighten the supplied bolts and nuts to clamp the joint securely.

• Weld flange to pipe end—edge design assists tack welding and alignment.
• Place gasket between flanges to ensure a gas-tight seal.
• Use M10 bolts and nuts to draw flanges together; torque evenly across fasteners.

Where can I use these flanges in a vehicle or fabrication project?

These two-bolt flanges are versatile connectors for exhaust systems, turbocharger plumbing, mufflers, resonators and custom piping runs. They are suited for repair, replacement or custom fabrication where a removable joint is required.

• Compatible with exhaust, silencer and muffler connections.
• Useful for turbocharger and intercooler piping transitions in custom setups.
• Handy for garages, exhaust shops and DIY fabricators needing serviceable joints.

Who is this for: This EVIL ENERGY flange kit is intended for mechanics, exhaust specialists and experienced DIY fabricators who need a durable, reusable connection on 2.5" exhaust systems. It’s ideal when you want stainless-steel longevity, reliable sealing with gaskets, and a weldable flange face for repeatable, serviceable exhaust joints.
