Flapper valve warranty

[KShi]

Does anyone know what the flapper valve is warrantied under? I cut off my muffler thinking the baffles were bad (still might be) and noticed the flapper valve flapper was broken off and in the muffler.

I would think it is covered by the 36,000 bumper-to-bumper warranty.

3/36.  You may still be ble to warranty that.   If you can, see if you can talk the dealership into installing the GM performance exhaust and you pay the difference in cost of the two.  I’ve seen it done.
