exhaust

i have installed a cat back system on my 1991 acura integra which has a b16 engine. the cat back is a stainless steel type r piping, if i use a catalyitic from a 1997 type r what type of header could i use, i was thinking of a 5zigan header 94 -99 integra gsr or civic si 99 -2000. what oter set ups do you guys recomend

With the Type R cat you wouldn't be able to use the Si header. The flanges wouldn't match up. The GSR should will work. :D
