Well a couple months back my 2000 CAMARO z28 a4 started making a decently loud ticking noise at idle. I checked out the engine and no noise up top, u can't really hear it in the engine bay. But if u look under the car it sounds like it's coming from the passenger side header near collector . I'm trying to find a leak but can't pin point exactly where the noise is coming from. I also can't feel any exhaust escaping any joints?

Anyone have this issue? Any tips on pinpointing the leak and fixing it?

I miss not ticking at idle, it drives me mad!
