So been reading around, and have seen UK mod being throw around, searched for it, and have yet to find a solid explanation thought I found a thread that point me to a local muffler shop that does it for cheap! Anyways, just wondering what I tell the guy to do when i take it in, since i'd just get a weird look if i said i want the "uk mod"

scroll to 2 and 3rd pics (not video).

you will see that the there is a new short pipe welded between the U from the muffler and the pipe coming from the engine. That is the uk exhaust mod. People have said the new pipe can range from 28 to 38mm in diameter depending on tone you want

 

tell them you want a muffler bypass and show them the pictures

 

Oh okay, I see it now. Thanks guys!
