Header Buddy is an innovative new design for header to exhaust connections that eliminates the need for traditional gaskets. This unique system creates a tight, leak free seal without using a separate gasket, saving time and money on repeated gasket replacements and exhaust shop visits. No more crawling under the vehicle to replace blown gaskets and no more dealing with constant exhaust leaks. Header Buddy is constructed from heavy duty 16 gauge aluminized steel tubing and features a 3 inch outside diameter inlet designed to fit standard 3 inch collector boxes. The flanges are 5/16 inch thick for strength and durability, ensuring a solid, long lasting connection. Sold as a pair for dual exhaust systems. For best results, do not over tighten during installation. Ideal for performance builds, custom exhaust systems, and anyone looking for a reliable, maintenance free alternative to traditional header gaskets.
