NOOO theres not glass in all mufflers just glass packs and its not really glass it fiberglass i think you cant break it just the longer you have the glass pack on your truck hopefully u have a truck anyway it will get louder but i mean a long time if you want your ride to be loud get an exhaust cut out check out QTP exhaust cut outs theyr electric so its kinda nice u can have the ride sound quite when u need it or want it to and SUPPPER loud when u want it to it basically bypasses your muffler tunrin yo **** into straight pipe kinda anyway you shouldnt put a cut out before any cats always make sure to put it after the very last cat
