heres just a trick i learned, um... im not responsable for anythign that happens, but my dad used to tell me how he used to get his lowrider tuck and have his glasspacks and drive around till it bot real hot, then spray water where the glass was and hte glass would crack, and as the glass cracked it got louder everytime he did this, i did this to my car, it worked, its basically taking the packing out of your car and having just like a can at the end.
if you dont wanna mess ur exhaust up dont do it, its just something i did, and wanted to share, it takes time , give it a few days or a week or so, it will get louder.

please dont post back saying im dumb or whatnot, i dun wanna hear it, i know youl pprobably find some reason to critisice me but hey, i got my muffler for free so i dont really care what happens to it.
