well yesterday me and a buddy tore out the whole exhaust system and put in slps long tubes and loudmouth 2 cat back. it was pretty much straight foward as for headers go. the only real problem i had was that when i tried to get the front 2 o2 sensors out, i pretty much riped the threads right off. it was like they where cross threaded in. then came the problem of finding o2 sensors for a 06 on a sunday. :willy: but in the end it was worth it because now it sounds just plain nasty.
