Product Details

The Honda OEM Exhaust Flexible Joint Bolt is a genuine factory replacement designed for select Honda Civic, Accord, CR-V, and Odyssey applications. This exhaust bolt is used at spring-loaded exhaust flange connections, helping maintain proper tension and a secure seal while allowing normal movement between exhaust components.

Over time, exhaust bolts can become corroded, damaged, or seized from repeated heat cycles and exposure to road conditions. Worn or damaged hardware may contribute to exhaust leaks, rattling noises, and difficulty securing exhaust components properly.

Manufactured to Honda's original equipment specifications, this flexible joint bolt provides precise fitment and dependable durability. It's an excellent replacement during exhaust repairs, catalytic converter servicing, header installations, and factory exhaust restorations.

I had to replace a couple exhaust bolts when I broke a rusty one. I appreciate the convenience of getting both items together. It reduces the guesswork and you do save a little from dealership prices. As always great service and fast shipping sweeten the deal with KSeriesparts.
