• Installation hardware

Flowmaster offers different exhaust series and sound levels, allowing drivers to choose a system based on the character they want from their vehicle.

Flowmaster Axle-Back Exhaust Systems

For enthusiasts primarily interested in changing exhaust sound and appearance, a Flowmaster axle-back exhaust system can provide a more focused upgrade.

Axle-back systems replace the rear section of the exhaust on compatible applications while retaining more of the factory exhaust system.

Depending on the vehicle, an axle-back system can provide:

• More aggressive exhaust tone
• Upgraded mufflers
• Performance exhaust tips
• Improved rear styling
• Straightforward installation
• Factory-style mounting where specified

Axle-back systems can be an excellent option for drivers who want a noticeable exhaust upgrade without replacing the complete cat-back section.

Flowmaster Direct-Fit Mufflers

Flowmaster direct-fit mufflers are engineered for compatible vehicle applications where replacing the factory muffler with a performance alternative is the primary goal.

Unlike universal mufflers that may require custom fabrication, direct-fit options are designed around specific applications for a more straightforward installation.

Depending on the product, a direct-fit Flowmaster muffler can provide a deeper exhaust tone, improved exhaust flow, and a more performance-oriented driving experience.

Always verify exact vehicle, engine, wheelbase, cab, drivetrain, and exhaust configuration where applicable.

Flowmaster Performance Mufflers

The Flowmaster muffler is at the heart of the brand’s reputation.

Flowmaster offers multiple muffler designs and sound levels, allowing enthusiasts to build an exhaust system around their preferred combination of tone, performance, packaging, and vehicle use.

Depending on the series, Flowmaster mufflers can range from relatively mild to extremely aggressive.

Available designs may include chambered and straight-through configurations, depending on the product family.

Flowmaster mufflers can be used for:

• Muscle cars
• Performance cars
• Trucks
• SUVs
• Jeeps
• Classic vehicles
• Hot rods
• Street builds
• Off-road vehicles
• Custom exhaust systems

When selecting a universal muffler, verify inlet and outlet diameter, configuration, case dimensions, available installation space, and intended sound level.

Flowmaster Exhaust Series

Flowmaster offers several exhaust families designed to provide different sound characteristics and performance options.

American Thunder

Flowmaster American Thunder systems are designed for enthusiasts seeking the recognizable Flowmaster performance sound and a more aggressive exhaust character.

American Thunder systems are available for numerous muscle car, truck, SUV, and performance applications.

Outlaw Series

Flowmaster Outlaw exhaust systems are positioned toward drivers looking for an especially aggressive exhaust tone.

These systems are well suited to enthusiasts who prioritize a bold exhaust note and performance-oriented character.

Sound level varies by application, so check the individual system before purchasing.

FlowFX

Flowmaster FlowFX exhaust systems and mufflers use a straight-through muffler design rather than Flowmaster’s traditional chambered configuration.

FlowFX provides another option for enthusiasts seeking performance exhaust flow with a different sound character from classic chambered Flowmaster mufflers.

Force II

Flowmaster Force II systems are designed for drivers who prefer a milder exhaust tone while still upgrading from the factory exhaust.

Force II can be particularly attractive for daily-driven vehicles where a more controlled interior and exterior sound level is preferred.

Signature Series

Flowmaster Signature Series represents a premium exhaust option featuring 304 stainless steel construction on current systems and an aggressive-to-moderate exhaust character.

Signature Series applications are designed for enthusiasts seeking a combination of premium materials, performance, sound, and appearance.

Always compare individual products because construction, sound level, configuration, and vehicle fitment vary throughout the Flowmaster lineup.

Flowmaster Exhaust Sound

One of the primary reasons enthusiasts choose Flowmaster is sound.

Different Flowmaster systems can produce significantly different exhaust characteristics. Depending on the muffler and vehicle application, available sound profiles can range from:

• Mild
• Moderate / Mild
• Moderate
• Aggressive / Moderate
• Aggressive

Engine displacement, cylinder count, forced induction, factory resonators, catalytic converters, exhaust tubing, vehicle body style, and other factors can all affect the final exhaust note.

For this reason, the same Flowmaster series may sound different across different vehicles and engines.

Always use the sound rating of the specific product as your primary reference when choosing an exhaust.

Flowmaster Chambered Mufflers

Flowmaster is especially well known for its chambered muffler technology.

Rather than relying exclusively on conventional packing material, applicable Flowmaster mufflers use internal chambers to manage exhaust pulses and sound energy.

This design is responsible for much of the traditional Flowmaster sound enthusiasts associate with classic muscle cars, trucks, and performance vehicles.

However, not every Flowmaster muffler uses the same internal architecture. Products such as FlowFX use a straight-through design, so choose the muffler series based on your desired sound and application.

Flowmaster Headers

Flowmaster also offers performance headers for select vehicle applications.

Headers are designed to improve exhaust-gas evacuation from the engine and can support improvements in throttle response and performance when correctly matched to the vehicle and exhaust system.

Current Flowmaster header offerings include Scavenger Series Elite Headers for select late-model and classic applications.

Depending on the specific header, features may include:

• Shorty or long-tube configurations
• Stainless steel construction
• Ceramic coating
• Heavy-duty flanges
• Factory-style or ball-flange connections
• Vehicle-specific installation

Emissions legality varies significantly by header and vehicle application. Always verify the individual product’s emissions information before purchase or installation.

Flowmaster Catalytic Converters

Flowmaster offers catalytic converters for select replacement and exhaust applications.

Current offerings include direct-fit and universal Federal catalytic converters designed for applicable 49-state vehicles.

Catalytic converter selection requires careful attention to:

• Vehicle year
• Make and model
• Engine
• Emissions certification
• Installation location
• Federal or California emissions requirements
• Direct-fit versus universal configuration

Never assume a Federal catalytic converter is legal for use in California or another jurisdiction requiring CARB-approved replacement converters.

Always verify emissions legality for the specific vehicle and location before ordering.

Flowmaster Exhaust Tips

Complete the appearance of your exhaust with Flowmaster exhaust tips.

Depending on the product, available options may vary by:

• Inlet diameter

Flowmaster Exhaust for Jeeps & SUVs

Flowmaster also offers exhaust systems for select Jeep and SUV applications.

These systems can provide upgraded sound and appearance while retaining vehicle-specific routing and mounting where specified.

For off-road vehicles, exhaust placement can be particularly important. Always consider ground clearance, bumper configuration, suspension modifications, and aftermarket accessories when selecting or installing an exhaust system.

Stainless Steel vs. Aluminized Steel

Flowmaster exhaust products may use different materials depending on the system and price point.

Stainless Steel

Applicable Flowmaster stainless steel systems provide increased corrosion resistance and are generally preferred for vehicles exposed to moisture, winter weather, road salt, or long-term ownership.

Aluminized Steel

Aluminized steel provides a more economical way to upgrade exhaust sound and performance and is used in select Flowmaster systems and mufflers.

Material specifications vary by product. Always check the individual listing to confirm construction before ordering.

Vehicle-Specific Fitment

Flowmaster exhaust fitment can depend on much more than year, make, and model.

Before ordering, verify all applicable vehicle details, including:

• Model year
• Make
• Model
• Engine
• Cab configuration
• Bed length
• Wheelbase
• 2WD or 4WD where specified
• Body style
• Factory exhaust configuration
• Factory emissions equipment
• Exhaust inlet and outlet configuration
• Selected Flowmaster part number

Do not assume an exhaust system designed for one engine, wheelbase, cab, or drivetrain configuration will fit another.

Always use the individual product listing as the final fitment reference.

Installation

Installation requirements depend heavily on the Flowmaster product.

Many vehicle-specific cat-back and axle-back exhaust systems are designed as bolt-on upgrades using factory-style hanger locations and supplied hardware where specified.

Other products—including universal mufflers, headers, catalytic converters, and builder components—may require:

• Cutting
• Welding
• Exhaust fabrication
• Additional hardware
• Specialized tools
• Professional installation

Exhaust components become extremely hot during operation. Installation should only be performed after the vehicle and exhaust system have cooled completely and the vehicle has been safely supported.

Emissions & Street-Legal Considerations

Exhaust regulations vary by vehicle, product, state, and local jurisdiction.

Cat-back and axle-back systems generally modify exhaust components downstream of the catalytic converters, but sound regulations still apply.

Headers and catalytic converters require additional attention because they may affect emissions-controlled components.

Always verify:

• Product emissions designation
• CARB Executive Order information where applicable
• Federal emissions requirements
• State requirements
• Local exhaust sound laws
• Intended street or competition use
