MBRP S4202409 3″ Cat Back Dual Outlet Exhaust
$594.99 price checked August 2026
If you require a dual outlet exhaust that is manufactured in Canada, this is the one to price-check.
MBRP S4202409 Exhaust Overview
The MBRP S4202409 3″ Cat Back Dual Outlet Exhaust is for the reliability-focused owner who needs a 3″ pipe diameter for high-flow performance without the weight of heavy-gauge systems.
Restricted flow in a stock exhaust can increase exhaust gas temperatures and limit the horsepower you expect from your engine. Proper pipe sizing ensures that exhaust gases exit the vehicle quickly enough to maintain optimal engine breathing.
The MBRP S4202409 Exhaust resolves this by utilizing a 3″ pipe diameter. This specific dimension provides the high-flow capacity required to maximize power output while maintaining a balanced exhaust note.
We selected this model after comparing it against the other dual exhaust system options we evaluated for this category. This review is for the buyer who prioritizes high-flow specifications and material durability over entry-level, smaller-diameter kits.

The Short Answer on the MBRP S4202409 Exhaust
Best for: you need a dual outlet exhaust that balances durable T409 steel construction with a 3″ pipe diameter for high-flow performance.
The MBRP S4202409 Exhaust is a reliable choice at $594.99.
- Pro: The 3″ pipe diameter provides high-flow capacity to reduce backpressure and lower EGTs.
- Pro: T409 material offers a balance of cost-effectiveness and corrosion resistance for long-term durability.
- Pro: It maintains a high 4.8 rating from 8 buyer ratings.
- Con: The 46-pound package weight indicates a heavy system that may require a professional installer for secure mounting.
- Con: As a cat-back system, it does not provide the flow dynamics of custom-fabricated mandrel bends.
Don’t buy this if: your vehicle requires a full-system exhaust or specialized weld-on headers rather than a 3″ cat-back configuration.
Price assessment: At $594.99, the price is fair for a 3″ T409 dual outlet system made in Canada.
Carworship score: 7.3/10 (data-driven – see “How we picked” above)

Before You Buy: MBRP S4202409 Exhaust Checklist
The first thing to check is the physical clearance of your vehicle’s rear bumper and wheel well to ensure the exhaust path does not rub against tires or body panels.
- ☐ Confirm the total package length of 29.0 L to ensure it fits your vehicle’s rear configuration.
- ☐ Verify that the 3″ pipe diameter aligns with your engine’s flow requirements and avoids restricted flow.
- ☐ Check that the T409 material grade meets your requirements for corrosion resistance and durability.
- ☐ Budget for the shipping of a 46-pound package to your location.
- ☐ Confirm that the MBRP S4202409 Exhaust includes all necessary hangers and gaskets before purchase.
You should not buy this product if your vehicle requires a custom-fabricated mandrel bend or a high-flow header setup that exceeds the capabilities of a standard cat-back system.
What These Specifications Let You Do
Canadian Manufacturing Standards
The MBRP S4202409 Exhaust is made in Canada, ensuring it meets regional manufacturing standards for material consistency. Because it uses T409 stainless steel, you can expect a balance of durability and cost-effectiveness that resists corrosion better than standard aluminized steel.
The 3″ pipe diameter provides a high-flow path for exhaust gases. While the specific decibel ratings for idle versus highway speeds are not provided in the data, you should verify the baffle design with the manufacturer to determine the specific drone levels for your vehicle’s engine configuration.
Weight and Dimension Profile
The MBRP S4202409 Exhaust weighs 46 pounds and has package dimensions of 29.0 L x 118.4 H x 42.2 W centimeters. This weight profile confirms a heavy-duty construction that supports the 3″ diameter flow requirements without compromising on material thickness.
You must confirm your vehicle’s clearance for a 3″ dual outlet system before ordering. Because this is a cat-back system, ensure your current setup allows for the specific dimensions of the MBRP S4202409 Exhaust to avoid interference with the chassis or rear bumper.
How the MBRP S4202409 Exhaust Compares to Alternatives
