Huge lump under passenger seat! wtf?? htf??

[Skrewdriver]

Took out passenger seat other day to see if i could put an amp under it,and noticed theres a hell of a big lump (approx 3 feet long,1 1/2 feet wide,2-3 inch high)under it!!!
Anyone had this problem before?couldnt find anything on thread search.
What would cause it to happen? Heat from exhaust/cat,etc? ,previous owner jacking up car in wrong spot?, high speed bumps pushing Ybend/cat up into floorpan??
Could probably bash the pan down again (???),but it might start to bulge again.
Anyone got a thought on this problem ,and how to fix / resolve it ? (its maybe more common that i thought)

The lump is for the catylic converter.
It's not going anywhere fast.



*I assume the lump is in the same spot on the ecotec powered commodores (it was on my buick powered sleds.)

Maybe there is already an amp under the carpet.

Perhaps it's a carpet python
