Exhaust leaking? Any aftermarket exhaust plumbing under wraps?
No that's what I thought at first. To me and I'm not a mechanic at all it sounds like maybe the water pump??? The sound goes faster with acceleration which has me worried.
....sound like a "ticking" noise at very fast pace?
Tick-tick-tick-tick-tick-tick type of sound???
No I know the sound you mean, you can only hear it at idle or when slightly reving the engine. When I got under the car it sounded like a pop/grind on the right or passenger side.
