I have this setup and it didn't match up at all they had to cut and weld ****... kinda regret getting them now the y-pipe hangs way too low and bottoms out like its its job.... The headers are really good but the y-pipe kinds sucks bad if you have a lowered car you might want to return them because your going to have a lot of problems (i got 1 1/2 inch clearence on a stock ride height). The only good thing is it sounds like a absolute monster with both cutouts open
