damn i never knew the flanges on the cats were different from differnt years

i knew that they were maybe differnt lenngths but i didn't know the flanges were angled differently :/

by the way wuts the lentgh diffence between the the 2 types?

thx

 

bump

isn't one of the headers longer?
on a 99+ or somthing?

are all the cats the same length?

 

94-99 gsr headers are shorter, and the 00-01 gsr is same length header as LS and ITR.

that i do know. i'm not sure about cat length,

i know with a 94 gsr exhaust and a ls/itr length header, the cat/test pipe needs about 12 or 16 inches, i forgot which one i had to have cut to. the stock cat is too long
