PALOZO 2-1/4 Inch Split Flange Repair Kit
The PALOZO kit uses two 2.25-inch split flanges with four screws, designed for 57 mm (2.25 inch) exhaust pipes. The flange thickness is 0.3 inches, and the kit includes corrosion-resistant galvanized steel with a silver zinc finish for durability. This option is best for owners seeking a straightforward, durable repair for a standard 2.25″ exhaust connection. The main limitation is that it fits only 2.25″ OD exhaust pipes, so verify pipe size before ordering.
Best for: Vehicles with a 2.25″ exhaust system seeking a ready-to-install repair set. Why: Includes all necessary fasteners and two split flanges for a quick, secure seal. Caution: Not compatible with pipes outside the 2.25″ ID/OD specification.

Buying Guide: Key Considerations for Exhaust Split Flange Kits
- Size compatibility: Confirm the internal diameter (ID) and outer diameter (OD) of your exhaust pipe. Match to 2.0″, 2.25″, or 2.5″ options to ensure a proper seal.
- Material and finish: Look for galvanized carbon steel or stainless steel with corrosion-resistant coatings to maximize longevity in heat and road conditions.
- Split design vs. single piece: Split flanges enable easier installation and maintenance on existing exhausts. Ensure the design and hole alignment match your existing flange.
- Bolt pattern and hardware: Check the number and spacing of bolt holes. Choose kits with the included bolts and nuts to minimize additional shopping.
- Application scope: Some kits target automotive exhausts, others are suitable for motorcycles or heavy-duty equipment. Choose based on your vehicle type and environment.
- Installation notes: Consider whether you need welding-free installation, gasket compatibility, and whether you have tools for bolt tightening or torque specs.
