Just installed IAW Quad tips on our M440i GC. Took about 4 minutes total. Fitment was great, and to my eye, the positioning is spot on.

We bought the 3.7" version, as that was recommended as having better fitment with the stock diffuser. Gaps are even all around, and size is proportional, so glad we went with this recommendation. Color was black chrome. Matches the other black quite well (pics don't show this as well).

Recommended.
