A ABIGAIL 4.0" Exhaust Band Clamp for 4" Pipes — 304 Stainless Steel, 3" Wide Strap, Reusable Bolt-On Seal

A ABIGAIL 4.0-inch stainless steel butt joint band clamp securely joins two 4" exhaust pipes or muffler sections without welding.

Designed for automotive exhaust repairs and custom installations, this heavy-duty band clamp couples 4" OD pipes using a corrosion-resistant 304 stainless steel strap, zinc-plated M10 hardware, a steel gasket, and an aluminum I-block to create a tight, serviceable seal. The clamp is reusable, resists distortion, and lets you disassemble the connection for maintenance or replacement.

How does this clamp hold two exhaust pipes together?

The clamp wraps around the butt joint between two 4" pipes and compresses the included steel gasket with the I-block and bolts to form a robust mechanical seal. Tightening the M10 flange bolts draws the strap inward evenly so the joint resists vibration and leaks without welding.

• 304 stainless steel strap prevents rust and maintains tension.
• Zinc-plated M10 flange bolts and nuts provide strong, corrosion-resistant tightening.
• Steel gasket and aluminum I-block concentrate clamp force for a uniform seal.

What exhaust parts can I use this band clamp on?

This clamp is suitable for a range of exhaust components where a 4" OD-to-4" OD connection is needed. It fits mufflers, catalytic converter interfaces, resonators, flex pipes, and tips, making it a versatile repair and installation element for most passenger vehicles and light trucks that use 4" piping.

• Muffler-to-pipe and pipe-to-pipe butt joints.
• Catalytic converter or resonator connections requiring serviceable joins.
• Exhaust tips and aftermarket custom exhaust assemblies.

How easy is installation and maintenance?

Installation requires only basic hand tools — loosen the bolts, position the clamp around the butt joint with the gasket and I-block in place, then tighten the flange bolts evenly. The clamp is designed to be reusable, so it can be removed and reinstalled for servicing or part replacement without damaging the pipes.

• No welding required — quick bolt-on service saves time.
• Reusable without deforming the exhaust components.
• Pre-tested strength and clamp retention for dependable repairs.

What size and materials should I expect?

This model is built for connecting two pipes each with a 4.0" outside diameter and uses a 3.0" (76.2 mm) wide strap for wide contact area and load distribution. Materials are chosen for durability and corrosion resistance under exhaust system conditions.

• Fits 4.0" OD pipe to 4.0" OD pipe.
• Strap width: 3" / 76.2 mm for solid coverage.
• 304 stainless steel strap, zinc-plated M10 hardware, steel gasket, aluminum I-block.

Who is this for: Mechanics, DIY enthusiasts, and custom exhaust fabricators who need a reliable, serviceable clamp for 4" exhaust systems. If you want a long-lasting, non-permanent connection for mufflers, catalytic converters, resonators, or exhaust tips that resists corrosion and allows future disassembly, this A ABIGAIL 4" butt joint band clamp is built for that role. For any issues, customer service offers troubleshooting, replacement parts, or refund options to ensure satisfaction.
