[QUOTE="S76, post: 1004130, member: 1349"] I've never seen pipes looking like that and have a hard time believing it is caused by idling. Did you check for a mouse nest in the air filter box? That would give you a rich mixture causing the CATS to go into after burner mode. The sniff test may not show the rich problem due to the relatively small throttle required to rev it up in neutral. You said it wasn't like that when you got it......something has changed. [/QUOTE]
