OBX header and downpipe??
I don't know of any numbers but on a ss/sc or on your car I wouldn't put it on as the primaries and dp are too small for the power we make, its restrictive.
get a header with at least a 1.7 primaries
get a header with at least a 1.7 primaries
and as far as the dp..its 2.5
the downpipe is 2.5 OD , i had one its 2.25ish ID
oh and it sounds HORRID, unless you get a cat
