I have this flowtec combo I bought in 97 just installed . The flange on each side Has one bolt real close to the crossmember . I was just baerly able to tighten one is not very . Also the Y pipe is real tight to the body conecting to the cat . I'ts like it was bent wrong any one ealse have this problem .I wouldnot recomend them to other's although I do not know if they have improved . Sorry for the dumb post just read shifty's I will try and preform more serches from now on I gess they do suck.

 

My pax side header collector is really close to the frame, but at least when the engine torques, it torques the other way. I remember having to heat up my ypipe and give it a good bending to make it match up to my cat, too. But hey, for $100, that'll work for me.
