Simons exhaust on a 122s, occasional pinging noise

I recently swapped in a simons sport exhaust into my 122s to replace the rusty glass pack crap the previous owner had on it. It all seems to have worked out rather well. Although I am getting an odd pinging noise. I don't think it is knocking. It sounds like a metallic ping. It'll happen once every minute or two.

Also how close should this exhaust fit to the bottom of the car? There is very little clearance. Could that be because I am running stiffer 164 engine mounts?

Sounds great though.
