OBX 2.5\" Stainless Resonator Pipe | 2006-2009 Mitsubishi Eclipse 2.4L 4G69

Restore or upgrade the exhaust on your 2006-2009 Mitsubishi Eclipse 2.4L 4G69 with this legacy OBX Racing Sports stainless resonator pipe assembly. The formed vehicle-specific section combines nominal 2.5-inch exhaust connections, an integrated resonator canister, and two threaded oxygen-sensor ports in one polished assembly.

The actual component has been photographed, measured, and inspected in house by Kuku Performance. The listing photos document the approximately 28-inch overall length, both pipe-end measurements, straight-tube measurement, resonator diameter, sensor-port layout, welds, and overall shape so buyers can compare this part with the exhaust currently installed on the vehicle.

Nominal 2.5\" Connections

Both connection ends measure approximately 2.5 inches outside diameter, including one expanded slotted slip-fit end for clamp-style assembly where the mating system allows.

Integrated 4\" Resonator

The polished stainless assembly includes an integrated resonator canister measuring approximately 4 inches across the body.

Dual Oxygen-Sensor Ports

Two opposed threaded oxygen-sensor ports are welded into the straight section adjacent to the resonator canister. Sensors and threaded plugs are not included.

Measured & Inspected In House

Kuku Performance photographs and measures the actual component so buyers can compare tubing, connection ends, sensor-port placement, welds, and measured dimensions before ordering.

Installation Information PROFESSIONAL FITTING IS RECOMMENDED

This is a vehicle-specific formed exhaust section, but it does not use factory-style bolt flanges. One end is expanded and slotted for a slip-fit clamp connection, while the opposite end is a formed pipe connection. Depending on the condition and configuration of the exhaust currently installed, installation may require cutting, fitting, clamping, welding, or additional exhaust hardware. No clamps or mounting hardware are included.

2.4L 4G69 Application Note

This OBX resonator pipe is intended for the 2.4L 4G69 four-cylinder Eclipse applications listed in the compatibility table. It is not listed for the 3.8L V6 GT, GT-P, or Spyder GT models.

Why This Matters: Eclipse trim names alone do not identify the engine. Verify that your vehicle has the 2.4L four-cylinder engine, then compare the existing pipe shape, connection diameters, resonator position, and two-sensor-port layout with the photographs before ordering. Vehicle Fitment - Verify Before Ordering

This listing is intended for 2006-2009 Mitsubishi Eclipse 2.4L 4G69 applications shown in the compatibility table.

• 2006: GS Hatchback 2.4L
• 2007: GS Hatchback, SE Hatchback, and Spyder GS Convertible 2.4L
• 2008: GS Hatchback, SE Hatchback, and Spyder GS Convertible 2.4L
• 2009: GS Hatchback and Spyder GS Convertible 2.4L

Not listed for: Any 3.8L V6 Eclipse GT, GT-P, GT SE, Spyder GT, or Spyder GT-P application.

Exhaust systems are frequently modified during the life of a vehicle. Before ordering, inspect the current exhaust and compare its routing, pipe diameters, connection points, sensor locations, and available installation space with the detailed photographs. Vehicles with replacement or custom exhaust components may require additional fitting or fabrication.

Legacy OBX Application: CAT11357 is legacy OBX inventory for the fourth-generation Mitsubishi Eclipse 2.4L. Exact replacement inventory for this application is increasingly difficult to locate. Rather than relying on incomplete legacy catalog data, Kuku Performance photographed and measured the actual component. The listing images show both sides of the assembly, both pipe-end diameters, straight-tube diameter, overall length, resonator body diameter, and oxygen-sensor-port placement so the part can be evaluated before purchase. Kuku Inspected & Prepared: This is legacy OBX inventory. Packaging may show normal warehouse or shelf wear. We inspect the resonator body, formed tubing, connection ends, sensor ports, and visible welds before shipment. The photographs and measurements in this listing are intended to identify the actual style, construction, and dimensions of the component being sold.

Please review the complete photo set before ordering. Detailed views show the overall shape, polished finish, resonator canister, visible welds, threaded sensor ports, both connection ends, and all measured dimensions.

If your Eclipse already has aftermarket exhaust work or you are unsure about the connections currently on the vehicle, message us before ordering. We would rather help compare the photographs and measurements than guess about a modified vehicle.
