Okay my friend who works at a scrap yard just brought me an Apexi GT spec system today in fairly good shape besides from some scratches and a seem that I am going to weld at work tomorrow. Yet here is the problem , when I was cleaning the canister today I noticed the internal packing was moving around inside the muffler. It sounded as if all of it was intacked just wondering if that would cause the system to be worthless I mean I got it for free so no big deal if it is just wanting to know before I put more of my time into it and come to find out its nothing but junk.
