K well I had a gsr EG ..had dc headers/a test pipe/and a greddy turbo BL exhaust..I boosted that car so i had the headers.test pipe on the side...I sold the car n bought a gsr teg....I put the headers/test pipe on n it pushed the piping back a little to where it would hit the gas tank at the curve...I got the piping re welded already shorter..but I would like to buy a greddy SP2 full cat back...So i was wondering which b series dc header might be a little longer than the stock gsr manifold cause the test pipe was same size as the sotkc cat so i assume the header is longer....what u think?

 

i assume you use a 94-99 gsr header before? 00-01 gsr header's should be longer.
