993 Catbypass pipes/cross pipes are different for certain years. 1994-1996 1/2 993's and all 993 SUPERCUP cars (1994 to 1997 993CUP) have Bischof oval 3 bolt flanges. 1996+1998 993's are all Gillett round 3 bolt flanges. YOU MUST CORRECTLY specify flange type when Ordering. When in doubt go check especially the late 1995 and early 1996 cars as this was a “cross-over year” and flange style changed during the year.
