The Verdict, and the Basis for It
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust is the top choice for a Dual Outlet Exhaust for ford bronco because it provides a large 3-inch pipe diameter for maximum flow.
Choosing a new exhaust can be difficult when you have to balance aggressive sound with the risk of drone or restrictive backpressure. If the pipes are too small, you lose horsepower; if the muffler chamber is poorly sized, you end up with a vibrating cabin at highway speeds.
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust solves these flow issues with its 3-inch diameter and T409 material. You should consider the Gibson Performance 17303 if you prefer T-304 stainless steel, or the Shop Line Dual Exhaust System 2.5 AL if you need a high-volume budget option.

Each Pick, Reviewed
The 3 picks below run from $178.49 to $594.99, reviewed in rank order.
MBRP S4202409 3″ Cat Back Dual Outlet Exhaust
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust represents the premium high-performance option for the Ford Bronco. We selected this system because it offers the largest pipe diameter in our comparison, targeting owners who prioritize maximum flow and a high-end build.
What we like: This system features a 3″ pipe diameter, which provides a higher flow ceiling than the 2.5″ alternatives. It is constructed from T409 stainless steel and carries a 4.8 rating from 8 buyers. The 46-pound package weight indicates a substantial build for a cat-back configuration.
Keep in mind: The T409 material provides good durability, but it does not offer the same corrosion resistance as T304 stainless steel. This system is best suited for owners who prioritize flow volume over maximum rust-proofing.
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust uses 3″ piping, which provides significant clearance for high-lift jacks and oversized tires compared to smaller diameter systems. Regarding the material, this unit uses T409 stainless steel rather than T304.
Gibson Performance 17303 Split Rear Dual Exhaust Kit
The Gibson Performance 17303 Split Rear Dual Exhaust Kit serves as the mid-range specialty choice for this list. It balances high-quality materials with a split-rear configuration that is popular for its specific aesthetic and sound profile.
What we like: This kit includes 3.5 in. stainless tips and is constructed with T-304 High Polished Stainless Steel. It features a Superflow Performance Aluminized Muffler and carries a 4.2 rating from 118 buyers. The $259.99 price point offers a mid-range entry into high-grade stainless steel components.
Keep in mind: The 2.5 in. pipe diameter is smaller than the 3″ MBRP option, which may limit top-end flow for high-horsepower builds. This kit is ideal for the buyer seeking a balance of durability and style.
The Gibson Performance 17303 Split Rear Dual Exhaust Kit uses 2.5 in. piping to ensure clearance for off-road equipment and large tires. The construction utilizes T-304 stainless steel, providing high resistance to corrosion from mud and salt.
Shop Line Dual Exhaust System 2.5 AL
The Shop Line Dual Exhaust System 2.5 AL is the high-volume, budget-friendly option for the Ford Bronco. We selected this system for buyers who need a functional dual outlet setup that remains compliant with the Clean Air Act without a high price tag.
What we like: At the $178.49 mark, this is the most affordable option in our comparison. It features a 2-chamber muffler and includes slash cut weld on 18″ Chrome Tips. The system is designed to retain all emissions control devices while providing a dual outlet exit.
Keep in mind: This system uses aluminized steel rather than stainless steel, which may require more frequent inspection for surface rust. It is best for the budget-conscious buyer who wants a dual-pipe look and basic performance gains.
The Shop Line Dual Exhaust System 2.5 AL uses 2.5″ aluminized mandrel bent piping to maintain clearance for high-lift jacks and oversized tires. This system is made of aluminized steel rather than T304 stainless steel.
You might also consider exploring the alternatives to a dual exhaust system to achieve similar power gains.
What Separates One Dual Exhaust System From the Next
Pipe Diameter Consistency
Prioritize pipe diameter consistency to ensure smooth gas flow and prevent backpressure. A 3″ diameter, like the MBRP S4202409, provides the highest flow volume for performance, while 2.5″ options like the Gibson Performance 17303 and Shop Line Dual Exhaust System 2.5 AL offer a balance of sound and flow. Larger diameters increase the exhaust note’s volume and depth significantly, moving from a subtle hum toward a more aggressive roar. Because these systems are aftermarket, you should confirm that the pipe diameter matches your vehicle’s factory requirements to maintain your warranty and avoid restricted flow. The MBRP S4202409 separated the field by offering a larger 3″ diameter compared to the 2.5″ options.
Tip Diameter Compatibility
Tip diameter compatibility ensures the exhaust exits align with your rear bumper cutouts. You should choose tips that match or slightly exceed your vehicle’s factory diameter to ensure a clean fit. The Gibson Performance 17303 includes 3.5 in. stainless tips, which provide a larger visual profile than the 2.5 in. pipes they are attached to. For the Shop Line Dual Exhaust System 2.5 AL, you must verify that the 18″ chrome tips fit your specific Bronco bumper configuration before ordering. Since these are external aesthetic components, confirming the physical dimensions of your bumper’s openings is a necessary step before purchase.
Resonator Placement
Resonator placement dictates how much drone and vibration occur inside the cabin at highway speeds. Look for systems that utilize specific muffler chamber counts, such as the 2 chamber design found on the Shop Line Dual Exhaust System 2.5 AL, to dampen unwanted frequencies. Proper resonator placement prevents the “drone” failure mode where incorrect chamber sizing causes cabin vibration. If a system does not specify internal resonator placement, you must confirm the muffler’s internal baffling with the manufacturer to ensure it meets your noise preferences. These systems are designed to retain all original emissions control devices, ensuring the modification does not void your vehicle’s emissions compliance.
Hanger Bolt Alignment
Hanger bolt alignment determines how the system secures to the chassis and prevents sagging. You need to verify that the pre-drilled hanger holes on the new kit align with your Bronco’s factory mounting points. The MBRP S4202409 is a cat-back system, which typically starts behind the catalytic converters, simplifying the alignment process. Because incorrect mounting can lead to heat shielding failure or rattling, you should have a qualified installer confirm the hanger positions against the chassis. Always check that the hanger spacing on the kit matches your vehicle’s frame geometry before the kit is shipped.

Questions Buyers Ask Before Choosing
Does the dual outlet exhaust kit include hangers and gaskets?
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust, Gibson Performance 17303, and Shop Line Dual Exhaust System 2.5 AL include the necessary piping and mufflers, but you must confirm if the specific kit includes hangers and gaskets before ordering.
