getting slp lm2 mufflers for christmas

well when i get them i am putting turndown on them for a couple of weeks to see if i like it that way. if i dont then i will get 2 1/2 exhust done for it. even if i buy it all seprate it will still cost like 20-30 dollars less to get it done my self
 
dont worry i will. as soon as i get them on i will hake a video of it. when i put the turndown on instead of putting them straight down i will put them at an angle so the dust will go out instead of hover up. and get a lil more sound out.
