Exhaust Components

What This Category Covers

The Exhaust Components category groups the small parts that hold an exhaust system together and make it fit right. This includes exhaust gaskets, flange hardware, hangers and mounts, wrap and heat shielding, electronic valve controllers, oxygen sensors, exhaust brakes for diesel trucks, and raw mandrel bend tubing and pie cuts for custom fabrication.

Categories Included

Exhaust gaskets (MLS, manifold, turbo flange, and muffler gaskets), exhaust adapters and reducers, exhaust cutouts and electric valve systems, exhaust hangers and rubber isolators, exhaust wrap and heat sleeving, oxygen sensors and wideband air fuel sensors, diesel exhaust brakes, mandrel bends, pie cuts, and titanium or stainless tubing for custom builds.

Exhaust Gaskets and Flange Hardware

A tight seal at every joint keeps exhaust leaks and drone out of a system. Multi-layer steel manifold gaskets, turbo flange gaskets, and muffler gaskets from Ticon Industries, HKS, Victor Reinz, and MAHLE ship in single and multi-packs sized to common tube diameters and bolt patterns.

Matching Gaskets to the System

Confirm the exact flange bolt pattern, tube inside diameter, and bolt count before ordering. Turbo-side flange gaskets differ from muffler-to-pipe gaskets, and 3-bolt versus V-band flanges are not interchangeable.

Exhaust Cutouts and Valve Controllers

Electric exhaust cutouts and valve controllers let a driver switch between a quiet street mode and an open, aggressive exhaust note on demand. Granatelli turn-down cutouts, Kies Motorsports valve controllers for Porsche platforms, and AWE Tuning AFM valve simulators for Camaro and Corvette are among the most popular choices in this category.

Choosing a Cutout System

Match the cutout diameter to the existing exhaust tube size and confirm whether the system needs a wired remote, Bluetooth control, or vacuum actuation before ordering.

Exhaust Hangers, Mounts, and Wrap

Rubber isolator hangers and billet titanium hanger rods from Ticon Industries keep an exhaust system secure while absorbing vibration. Exhaust wrap from Torque Solution and DEI reduces under-hood and under-body heat, protecting nearby wiring, hoses, and carbon fiber components on tightly packaged engine bays.

Oxygen Sensors and Wideband Sensors

OE-style and direct-fit oxygen sensors from NGK NTK keep factory fuel trim and emissions systems reading correctly on Honda, Acura, Nissan, and import platforms. Wideband air fuel ratio sensors from NGK NTK support aftermarket gauges and standalone engine management on Mustang, F-150, Audi R8, and Porsche Cayenne applications.

Sensor Fitment Notes

Confirm upstream versus downstream sensor position and connector style before ordering. A wideband sensor for a standalone ECU is not interchangeable with an OE-style narrowband replacement sensor.

Diesel Exhaust Brakes

Exhaust brakes for Cummins, Duramax, and Power Stroke diesel trucks use a valve in the exhaust path to add engine braking on long descents, reducing wear on the service brakes when towing. BD Diesel is a leading name in this category for diesel truck applications.

Mandrel Bends, Pie Cuts, and Custom Fabrication Tubing

Stainless Bros mandrel bends, Vibrant pie cuts, and Ticon Industries titanium tubing give fabricators the raw material to build a custom exhaust, header, or turbo downpipe from scratch. Bends are available in multiple radii, wall thicknesses, and leg lengths for header and downpipe fabrication.

Fabrication Tips

Match tube diameter and wall thickness to the rest of the system, and account for radius and leg length when planning clearance around subframes, floor pans, and heat shields.

How to Choose the Correct Exhaust Component

• Confirm the exact year, make, model, and trim before ordering a direct-fit part
• Measure existing tube diameter and flange bolt pattern for gaskets, adapters, and hangers
• Confirm the number of bolts and gasket layer count for manifold and turbo flange gaskets
• Check sensor position (upstream or downstream) and connector style before ordering an oxygen sensor
• Verify wideband sensor wire count and threading match your gauge or ECU input
• Confirm cutout or valve controller diameter matches the exhaust tube it will be installed in
• Check wrap width and length needed to cover the target section of pipe or manifold
• Verify mandrel bend radius, leg length, and wall thickness fit the planned routing
• Confirm hanger rod length and mounting style match the factory or aftermarket hanger bracket
• Plan for a tune after adding a diesel exhaust brake or after changing wideband sensor calibration

Common Questions

What is the difference between exhaust wrap and heat shielding?

Exhaust wrap is a fiberglass or ceramic material wound directly around a pipe or manifold to hold heat inside the exhaust tract, improving exhaust gas velocity and reducing under-hood temperatures. Heat shielding is a separate barrier, often a mat or sheet, mounted between the exhaust and nearby components like wiring, fuel lines, or carbon fiber panels.

Do I need a specific gasket for a turbo flange versus a muffler joint?

Yes. Turbo-side flange gaskets are engineered for higher heat and boost pressure and use a different bolt pattern than a muffler-to-pipe slip joint gasket. Always match the gasket to its specific location in the exhaust system.

Can I replace an oxygen sensor with any brand?

Direct-fit sensors must match the connector, thread size, and heater circuit of the factory sensor. NGK NTK direct-fit sensors are engineered to OE specifications for a wide range of Honda, Acura, and Nissan applications, but always confirm the year, make, and model before ordering.

What is a wideband oxygen sensor used for?

A wideband sensor reads a broader air fuel ratio range than a stock narrowband sensor and is typically used with an aftermarket gauge, data logger, or standalone engine management system for tuning boosted or modified engines.

Do electric exhaust cutouts require a tune?

No. Cutouts change exhaust sound and back pressure slightly but do not require an ECU tune on their own. However, removing a catalytic converter or muffler permanently for extended periods can affect emissions compliance and downstream O2 sensor readings.

What is a diesel exhaust brake used for?

An exhaust brake restricts exhaust flow to create engine braking, slowing a diesel truck on long grades without relying solely on the service brakes. This reduces brake wear and improves control when towing heavy loads.

How do I know what size mandrel bend I need?

Measure the inside diameter of your existing exhaust tubing and match that to the mandrel bend diameter. Also confirm the bend radius (measured in tube diameters) and leg length needed to clear chassis components in your specific routing.

Are titanium exhaust hangers worth the upgrade?

Titanium hanger rods from Ticon Industries save weight versus steel and resist corrosion, which matters most on track and show builds where weight savings and appearance are priorities. Steel hangers are perfectly functional for daily-driven street vehicles.

Do I need a tune after installing new exhaust hardware?

Simple hardware like gaskets, hangers, and wrap does not require a tune. Changes that affect exhaust flow significantly, such as removing a catalytic converter or adding an exhaust brake, may require a tune to keep O2 sensor readings and emissions systems functioning correctly.

Can I fabricate a custom exhaust with the tubing sold here?

Yes. Stainless Bros mandrel bends, Vibrant pie cuts, and Ticon Industries titanium tubing are sold specifically for custom header, downpipe, and exhaust fabrication. A qualified exhaust shop can weld these components into a complete system matched to your engine and chassis.
