where do i have to draw the line with exhaust products on an ls/vtec conversion

reason for asking is i want to buy this cat back for a gsr but i'm not sure if it will work
and i'm not sure but i assume the headers and downpipe will be gsr specific also right?

thank you

 

You would want to use LS or ITR header / exhaust.

 

so just to make sure i should use ls or itr headers for a gsr head?

not to question you but thats alot of money to throw out!!to not fit?

 

any b series header will bolt up to any b series head.
if youre going to buy a gsr catback, you need a gsr cat and gsr header. or use an ls or itr header and have a testpipe made.

 

wat kind of car do u have? LS or GSR? I'm using a gsr exhaust on mines and everything fits perfect...jus get a exhaust that matches the headers...
