I have a 96 A6 avant with an exhaust leak. It is either before or after the cat. Are the clamps/bolts and donought dealer items only? Are the sold in like a "kit"? Does anyone have a part number? I'm tired of waking the hood when the car starts up and runs.

Thanks.

 

You should confirm the location of the leak, wether it's a bad cat flange gasket, or an actuall broken weld on the cat.

A good locally owned exhaust shop should be able to hook youup with this.
