2.38" piping should be the perfect one for 20V. I was told that Apexi N1 uses this size too. However, it depends on individual trial and error.
yup correct...
just love that piping..the purplish colour...the more purple, the more "virgin" is the piping...
BTW got 2 sets for sale...Apexi N1 and Apexi GT...will get the price later, selling on behalf of friend...PM me...
