Hey guys i have a Greddy sp2 muffler and when i shake it you can here stuff inside move around sounds like dirt, rocks? does any1 have any idea what it might be? and should i be worried? the muffler is not installed in my car yet.

 

It could be debris or the packing or piping might be bad. Did u buy from a dealer? It may blow out or not.

 

yea i bought it from some1 ....u think a muffler shop can repack it and save it?

 

Its greddy... it was probably wack *** to begin with!

 

No it's pretty much junk once that goes
