If it's a wrx exhaust from a newage impreza, it should fit and pass nct if you still have the downpipe cats in place. If you have a decat, it'll fail the nct irrespective of whether you have the up-pipe or not. Hope this helps [emoji2]HI
Iv got a 05 forester with a wrx exhaust. Will it fit? And Will it still pass the NCT if I put on.
