your just wasting your time imo,because the converters on these trucks are pretty restrictive and just cutting off your tailpipe is kind of dumb and it's not really gonna be any louder.It's just gonna sound like your exhaust rotted off.Even if you cut off the muffler and straight piped it,it would still be quiet.Just depends on what you wanna do and in your case how loud your dad will let you have it.
