Anybody know what exactly is making the duck quack-like noise? I don't suspect the starter sine it does not come from the area where the starter is located. Most noticeable when rpms drop.

Mine did that when stock, though not as pronounced, the time it takes to come down in revs seems longer than mine too.

It sounds like a result of lower back pressure in the exhaust system. My car sounds similar to that now that I have a Warpspeed y-pipe on it.

It made the noise when I had oem exhaust even though i have the headers with y pipe into stock catback now.

I think it might be coming from the front of the motor around the oem pulleys.
