Does anyone know if you have to cut the crossmember to fit a 4 to 1 header on a b16 on a 88 rex?

 

use 90-93 integ x-members

 

i got 90 to 93 x members they dont fit.the mounting holes are in line with one another and the rex is off set.

 

well i guess the jdm ef8/9 sits higher and uses 90-93 integ x-members.

Yep My JDM EF-8 Has the same front member as a 90-93 teg... the US Civic/Crx have a different front member...... But even with the Hi-Tech header I still had to do some small trimming ..like about 1/2 of and inch. no biggie
