hi,

try to put D16Y8 header+ down pipe on EG,
the down pipe: does it need modification? ( cut / weld) ?


or just ignore it? ( would it be good ?)

thanks...

the downpipe needs no modification for fitment.

the collector can be enlarged for performance.

id "ignore" it if you only plan on running the stock cat converter/exhaust pipe diameter.

if you have upgraded those then enlarging the I.D. of the collector is a good idea.
