Hey...does anyone know if a axel back would bolt on to my stock piping for or not. Someone wants to sell his apexi dunk for 100...the axel back and im thinking of getting it. I can get it for 300 off the internet but im wondering if i should just buy this, put it on for now then later do the custom mandrel piping. I don't want to do it ghetto style and get it welded on to my stock piping. Just want to know if it will bolt on to it. Thanks.
