2.5" V-Band Header Collectors with Clamps – Set of 2

Build a cleaner, stronger, and more serviceable exhaust connection with these 2.5-inch V-Band Header Collectors from Certified Automotive Experts. Designed with a 2.5-inch inlet and 2.5-inch outlet, these universal V-band collectors provide a reliable connection between custom headers and exhaust tubing while eliminating the hassle of traditional 3-bolt collector flanges.

This complete kit includes two polished 304 stainless steel V-band header collectors and matching V-band clamps, giving you the essential components needed to integrate V-band connections into a custom exhaust system. The V-band design uses a precision metal-to-metal connection rather than relying on a conventional collector gasket, helping reduce potential leak points while making the exhaust easier to remove and service.

Whether you're building an LS engine swap, hot rod, muscle car, classic truck, race car, off-road vehicle, or custom performance exhaust system, these 2.5-inch V-band collectors provide the flexibility and serviceability needed for demanding builds.

V-Band Design for Easier Exhaust Service

Traditional exhaust collector connections often use 3-bolt flanges, bolts, and gaskets that can become difficult to remove after repeated exposure to heat and corrosion.

These 2.5-inch V-band collectors provide a simpler alternative. The supplied V-band clamp draws the matching flanges together to create a secure metal-to-metal connection.

The result is a connection that's easier to access when you need to remove the exhaust for:

• Transmission service

• Clutch replacement

• Engine removal

• Header replacement

• Exhaust modifications

• Performance upgrades

• General maintenance

Instead of fighting rusted collector bolts and worn gaskets, simply release the V-band clamp to separate the exhaust components.

Integrated M18 x 1.5 O2 Sensor Bung

Each collector includes a welded M18 x 1.5 oxygen sensor bung with a threaded plug already installed.

Because the O2 bung is integrated into the collector, you can rotate the assembly before tightening the V-band clamp. This gives you greater flexibility when positioning an oxygen sensor around:

• Frame rails

• Transmission cases

• Steering components

• Crossmembers

• Floor pans

• Chassis components

• Other underbody obstacles

The included threaded plug allows the collector to be installed immediately. The plug can later be replaced with a compatible factory-style or wideband oxygen sensor for EFI systems, tuning, and engine management applications.

304 Stainless Steel Construction

These V-band header collectors are manufactured from 304 stainless steel with fully welded seams. The stainless construction provides excellent durability in the high-temperature environment of a performance exhaust system while offering greater resistance to corrosion than typical mild-steel components.

The polished finish also provides a clean appearance for custom engine bays and exhaust installations.

Universal Custom Exhaust Application

These collectors are designed as universal exhaust components rather than vehicle-specific parts. They are ready to weld into a custom exhaust system where a 2.5-inch V-band connection is required.

Common applications include:

• LS engine swaps

• Hot rods

• Muscle cars

• Classic cars

• Classic trucks

• Race cars

• Off-road vehicles

• Street performance builds

• Custom exhaust systems

• Engine swap projects

• Competition and track builds

What's Included?

Each kit includes:

• 2 × 2.5-inch V-band header collectors

• 2 × matching V-band clamps

• 2 × M18 x 1.5 O2 sensor plugs

Product Specifications

Frequently Asked Questions

What size exhaust are these V-band collectors for?

These collectors feature a 2.5-inch inlet and 2.5-inch outlet, making them suitable for compatible 2.5-inch custom exhaust applications.

Are V-band clamps included?

Yes. The kit includes matching V-band clamps for both collectors.

Are these collectors made from stainless steel?

Yes. They are constructed from polished 304 stainless steel with fully welded seams.

Do they require a collector gasket?

The V-band connection is designed to create a metal-to-metal seal using the matching flanges and supplied clamp, eliminating the need for a traditional collector gasket.

Do the collectors have O2 sensor bungs?

Yes. Each collector features a welded M18 x 1.5 O2 sensor bung and includes a threaded plug.

Can I adjust the O2 sensor position?

Yes. The collector can be rotated before tightening the V-band clamp, allowing you to position the oxygen sensor for better clearance and accessibility.

Are these vehicle-specific?

No. These are universal weld-in exhaust components. Always verify your required dimensions and available clearance before installation.

What vehicles can use these collectors?

They can be used for a wide variety of custom projects, including LS swaps, hot rods, muscle cars, classic trucks, race cars, off-road vehicles, and custom performance vehicles, provided the dimensions and application requirements are compatible.

Installation & Fitment

These collectors are designed to be welded into a custom exhaust system. Professional exhaust fabrication or welding is recommended for installation.

Before purchasing, verify:

• 2.5-inch header/exhaust tubing compatibility

• Available underbody clearance

• V-band flange dimensions

• O2 sensor clearance

• Collector orientation

• Exhaust routing requirements

Because this is a universal component, vehicle-specific fitment is not guaranteed.

Why Choose 2.5-Inch V-Band Header Collectors?

If you're building a custom exhaust system and want a connection that's easier to service than a conventional 3-bolt flange, these V-band header collectors offer a practical solution. The 304 stainless steel construction, integrated O2 sensor bung, compact V-band connection, and included clamps make them well suited for performance-oriented custom builds.

The ability to quickly disconnect the exhaust can save significant time during future engine, transmission, clutch, or exhaust work.

Answer-First Summary

What are these?
These are a set of two 2.5-inch V-band header collectors made from polished 304 stainless steel. Each collector has a 2.5-inch inlet and outlet, an M18 x 1.5 O2 sensor bung, and comes with a matching V-band clamp.

What are they used for?
They are designed for custom exhaust fabrication, providing a serviceable V-band connection between headers and exhaust tubing.
