i odrered a 3inch catless form cobalt addiction, the piece of **** flange wouldnt line up with my stock cat-back like they say it would. i tried drilling them bigger and it barely held together for a week, drove open dp for like a week and a half, then had a shop bend me the 3 inch all the way back. either they lie and say it will fit, or the one they sent me wasnt welded on straight.

weird. mine fit no problem, and i don't remember hearing from anyone else that it didn't fit.

will sound like ****, and be VERY loud. but not a good loud.
