Exhaust Manifold Bolt and Spring Kit

Dorman 03114 is a direct replacement exhaust manifold bolt and spring kit for select Subaru applications. It is built to replace rusted or damaged exhaust fasteners and help maintain a secure seal between the exhaust pipe and muffler while still allowing the movement the system needs.

For Subaru Crosstrek, Forester, Impreza, Ascent, BRZ, Legacy, Outback, WRX, WRX STI, XV, Tribeca, and B9 Tribeca applications, this hardware is a practical service part when exhaust fasteners are worn, seized, or broken. The Dorman 03114 exhaust manifold bolt and spring kit is a standard replacement solution for front exhaust service.

• Direct replacement for select Subaru exhaust manifold fastener applications
• Helps prevent exhaust leaks at the connection point
• Spring design supports movement between the exhaust pipe and muffler
• Standard replacement grade for routine exhaust repair
• Steel spring construction with Grade 5 bolt
• Specific fit for confirmed Subaru front applications

Detailed Product Overview

This exhaust manifold bolt and spring kit is designed around the original fastener style used on many Subaru front exhaust connections. The bolt, spring, and nut work together to restore clamping force where corrosion or heat cycling has damaged the original hardware. Dorman 03114 is also a useful OE-style replacement for service work where the original fastener has lost strength or no longer holds the exhaust joint securely.

This part cross-references Subaru 44044AA010 for the same application.

Common Repair Uses

• Exhaust leak at the manifold or pipe connection
• Broken, rusted, or seized exhaust bolt hardware
• Loose exhaust joint causing noise or vibration
• Failed spring tension at the exhaust connection
• Service replacement during exhaust manifold or pipe repair

Installation Notes and Tips

Confirm the vehicle’s front exhaust fastener location before installation. Clean the mating surfaces and inspect the threads, flange, and surrounding exhaust components for corrosion or damage before reassembly. Because exhaust hardware is exposed to heat and road contamination, replacing worn fasteners during repair can help restore proper sealing and reduce repeat service.

Compatible with front applications on select Subaru models, including 2020-2026 Subaru Crosstrek, 2020-2026 Subaru Forester, 2020-2026 Subaru Impreza, 2020-2025 Subaru Ascent, 2022-2025 Subaru BRZ, 2020-2025 Subaru Legacy, 2020-2025 Subaru Outback, 2020-2025 Subaru WRX, and earlier Subaru front exhaust applications listed in fitment.

Quality Assurance

Dorman manufactures this part as a standard replacement exhaust hardware solution with a Grade 5 bolt and steel spring construction. The design follows the original fastener style for the listed Subaru applications and supports reliable exhaust service on the front connection point.
