Heat wrap would hold the heat inside your down pipe, now you have no protection. heat goes where?? up up and in to your intercooler. heat soaking it. top mounts are junk. then,now,and forever. IMO putting your stock shield back on it a deff. i dont think it will fit with a bellmouth d/p but you can try it 
yeah prob right about that bellmouth. still want to see pics of your downpipe
