EVIL ENERGY 4.0-Inch Exhaust Clamp – Stainless Steel Butt Joint Band Clamp Sleeve (2 Pcs) for Pipes, Mufflers, Catalytic Converters

Overview

When you’re building, repairing, or upgrading an exhaust system, you want a clamp that delivers strength without complicating the job. EVIL ENERGY 4.0-Inch Exhaust Clamp is designed for right sized, straightforward service on 4.0 inch OD pipes. The kit includes two identical clamps, making it practical for paired connections such as a pipe-to-pipe run or a quick join between a pipe and a muffler or catalytic converter. The hardware and band come together to form a compact, rugged coupling that you can count on in everyday driving and small shop projects alike.

Materials and construction

Key components are built to withstand heat, road grime, and vibration. The band is a durable 304 stainless steel, paired with a zinc plated M10 bolt and nut. A steel gasket supports a tight joint, while an aluminum alloy I-block distributes clamping force across the full 360 degree surface for a secure seal with minimal material deformation.

Performance and specs

• Size and fit: This lap joint clamp joins 4.0 inch OD pipe to 4.0 inch OD pipe. The strap width is 3 inches (76.7 mm).
• Fastening: The kit uses a zinc plated M10 bolt and nut with a steel gasket for a reliable connection.
• Sealing and torque: 360 degree load distribution creates a uniform seal; recommended torque is 63 N·m.
• Material quality: 304 stainless steel band offers corrosion resistance; aluminum I-block keeps weight practical without sacrificing strength.
• No-weld installation: The design allows quick assembly or removal without permanent modification.

What you can expect in real use

In the field, the clamp can simplify an exhaust repair or upgrade. It’s well suited for connecting a new muffler section to pipe, or pairing a catalytic converter with a pipe run. The combination of sturdy metal and thoughtful geometry gives you a confident, repeatable fit during routine maintenance or occasional alignment tweaks. While results vary with vehicle configuration and conditions, the clamp is designed to offer a dependable, serviceable option that doesn’t require welding or heavy modification.

Installation tips

• Prepare the pipe ends by removing rust, paint, and debris for a clean contact surface.
• Position the clamp evenly and snug the bolt to the recommended torque of 63 N·m.
• Check for alignment after tightening and re-tighten if needed after a short test drive.

What’s included

Two identical clamps are included per kit, giving you a symmetrical, ready-to-use solution for common exhaust pipe connections.
