A friend of mine has a weird ticket coming through his exhaust. We could slightly hear when he had Magnaflows. But now with Carvens it's really noticeable. You can hear it through the exhaust pipe. Mostly driver side I think. At first I thought it was the tick, but you can't hear anything in the engine compartment. The car runs fine. He did pull an O2 sensor code recently, but it was there before the code popped. No stumbles, no quirks. Pulls strong. A compression check and leak down is next on the list. Just thought I'd see if anyone else might have heard of this.
