How do I install the gasket and bolts safely?

Installation requires basic hand tools and attention to safety. Work only when the vehicle is cool, use protective gloves and eyewear, and follow torque specifications to avoid warping the flange.

• Gather tools: socket wrench, torque wrench, rust-preventive lubricant, wire brush.
• Remove old bolts and gaskets; clean mating surfaces with a wire brush to remove rust and debris.
• Center the new gasket, align bolt holes, hand-thread bolts, then torque evenly to specification.
• Avoid sealants; high heat can degrade compounds and clog the catalytic converter.

What are the key features and materials of this kit?

The parts are manufactured for heat and corrosion resistance to provide durable sealing where the catalytic converter meets the exhaust pipe. The kit includes extra bolts to replace any corroded or damaged fasteners.

• Kit contents: 4 catalytic converter gaskets and 10 bolts for complete flange repair.
• High-temperature and corrosion-resistant materials to withstand exhaust heat cycles.
• Designed to maintain a secure clamp and prevent exhaust leaks over time and rough roads.
• Supplied hardware covers common wear items so you can replace multiple fasteners at once.

When should I choose professional installation?

If you lack repair experience or the correct torque specs and tools, have a certified technician perform the installation. Professionals will ensure proper alignment and torque, reducing the risk of leaks and flange distortion.

• Recommended for those without experience working on exhaust systems.
• Professional install reduces risk of misalignment or over-torquing the flange.
• Service techs can inspect surrounding components and confirm correct part matching.
