I just bought my CME not the whole kit but just the tips, the 90deg. bends and the lower valence(bodykit). I was wonder if the 90deg. bends would hook right up to my stock exhaust after I cut the tips off. Or do you guys/girls know a way how to do this because the 90deg. bends are different lengths not sure which one goes on the left or the right(didnt come with instructions). Am I just going to have to go to an exhaust shop and have them fab me something up.

Also some pics would be helpful, thanks to any replies I get.
