2006 Honda Loud sounds/Bad cat? Sign In

(will get back on engine size and milage)

Randomly started sounding like a motorcycle. Bottom heat guard of cat converter is off, and when I splash water where it connects to pipe the loud sound briefly dissipates. Is sound due to leak ?

First - don't splash water at a hot converter or pipes! If looking for an exhaust leak if not obvious try with a helper to carefully restrict exhaust at tail pipe well guarding hands from heat if you try that while just feel for air at suspect spot without touching it or if noise is then louder alone right there a leak is likely.

Do you have the bottom half of the heat shield? Almost all when spot weld give out or just one like the top stuck there loose is going to rattle like nuts at times.

If you have both halves in decent shape except the spot welds I personally can fix most of those, others will suggest whole parts with new one that could include a converter that is fine otherwise.

Ask - if bad if just a shield can be replaced and not the whole pipe and converter if missing. IDK for sure but popular cars/vehicles may be selling those now to work as intended and it should,
