A ABIGAIL 4" Stainless Steel V-Band Clamp Kit — 4" OD Male/Female Flange for Turbo & High-Flow Exhausts

A ABIGAIL 4" stainless steel V-band clamp kit is a complete male/female flange assembly that joins 4" OD exhaust pipes quickly and creates a gasket-free seal ideal for performance and turbo applications.

This bolt-on kit includes matched male and female flanges plus a V-band clamp engineered to fit 4" outer-diameter piping. The flanges have a recessed opening so the pipe slips into the flange, producing an overlapping seam ready for welding and a consistent, compression-style connection when clamped. Constructed from stainless materials for corrosion resistance, the kit is sized for turbo piping, downpipes, catbacks, and other high-flow exhaust systems.

How does this V-band clamp simplify exhaust assembly and maintenance?

The V-band design replaces multi-bolt flanges with a single clamp that compresses the flanges evenly around the joint. This lets you attach or detach sections quickly—useful during fabrication, service, or when removing turbos or downpipes for access.

• One-nut removal for fast disassembly and reassembly
• Even radial pressure for a tight, gasket-free seal
• Recessed flanges allow for easy welding overlap
• Reduces leak points compared with multi-bolt connections

Will this fit my vehicle’s 4" exhaust pipe and turbo components?

This kit is meant to join two 4" OD pipes and is commonly used where a 4" outer-diameter connection is required. Confirm your pipe outside diameter is 4" and your thread requirements match M8 x 1.25 for the clamp fastener.

• Designed for 4" OD pipe-to-pipe joins
• Includes matched male and female flanges plus V-band clamp
• T-bolt thread size: M8 x 1.25 for compatibility with common hardware
• Works with downpipes, catbacks, turbo outlets, and performance exhausts

What are the material and durability features I should expect?

The kit uses stainless-steel components chosen to resist corrosion and tolerate high exhaust temperatures typical of turbo and high-horsepower systems. The recessed flange geometry and V-band clamp deliver a durable mechanical joint that withstands vibration and thermal cycling better than many gasketed flange setups.

• Stainless construction for improved corrosion resistance
• Recessed flange design for secure welding and overlap strength
• V-band clamp provides consistent clamp pressure around the bore
• Suitable for high-flow and turbocharged exhaust environments

How easy is installation and what’s included in the package?

Installation is straightforward for anyone familiar with exhaust work: slide pipes into the recessed flanges, align the male and female halves, then secure the V-band clamp. The package contains all parts needed for a single 4" joint, so no additional flanges are required for that connection.

• Includes 1 female flange, 1 male flange, and 1 V-band clamp
• Joins 4" OD pipe to 4" OD pipe with a ready-to-fit assembly
• T-bolt thread spec M8 x 1.25—compatible with standard fasteners
• Simple on/off with a single nut for quick serviceability

Who this is for: This A ABIGAIL 4" V-band clamp kit is aimed at hobbyist fabricators, performance shops, and vehicle owners who modify exhaust systems or service turbocharged engines. If you need a dependable, quick-release 4" pipe connection for downpipes, turbo outlets, or high-flow catbacks—and want a gasket-free flange solution—this kit provides the parts and geometry to get the job done efficiently.
