The 320i dual tub system is very slightly smaller in diameter than the 325i system by a couple of mm.
If you've put a 2.7 in it's time to upgrade to the 325i system.
The Boysen centre box is the best one, Boysen make Alpina exhausts and this one give a nice fruity note. Get them from Euro car prats.
