Well let me start off by saying i'm new to the site so I dont really know were to post this so i'm doing it here! Anyway the question I have is I just got a used Apexi GT spec exhaust system yesterday from a friend who works at a wrecking yard. The system is in really nice shape besides a seem that i'm going to weld and a few scratches. So I noticed that the internal sound reducing material moves around inside the canister and "Jiggles" around. Seems to be all together just moves around, so i'm not sure if that basically rendures the system useless. Got it for free so no big deal if it does just wanted to know before I put more time into fixing it.
