My Ark exhaust is acting up. First there was a gasket leak in the s-pipe to cat back flange. Fixed. Now the same noise but when I took it to the muffler shop try covered the tail pipe and had the car running and could not replicate any leaks.

Today, popped the hood and noticed the springy mount where the s pipe starts. Do
You think over time this has loosened andW is the source of a leak?

The sound that doesn't sound right is a crappy, flat nasty sound on deceleration.

i thought the same happened to me. but my o2 sensor snapped off the spipe. i have no clue how. car ran ____ty and it sounded like crapp

 

Well wouldnt I have a cel if my sensor came off? Either way, I'm having it looked at. I think the connector where the springs are is suspect.

 

i actually disnt even throw a cel till after i changed my spipe.
