something rattling in exhaust, any guesses?

[TXRickC]

Ive been recently hearing something (similar to pinging on my old '95 GT w/bad gas) around 2500-3000 RPMs.
stuck her up on stands and tapped around with a rubber mallet, seems to be near the rear of the exhaust past the connection from mid pipes and towards the rise to go over axle.

Car has 12,4XX miles, a shifter and resonator delete and driven casually.

Don't know much about the in's & out's and quirks of the GT500s so maybe someone else knows?

could be the cats coming apart.

Have you done any exhaust work recently? I had a loose bolt after a AB swap that caused a rattle. Even if you haven't touched the exhaust, pretty easy to make sure the hanger bolts (3 on each side) are tight.

heat shield
cats coming apart
loose bolt

Those are my guesses.. Let me know if I win!

sounding like it's a piece of something in the pipe.
The car has a MGW and Intake Resonator Delete, stock exhaust so it's not from anything done to the car. 12,4XX over 3 years and casually driven.

Ordered a 2.5" VMP pulley, SCT X4 and off-road H-pipe today so when I put that on I'll see if I can get a better look.
