But the 18 broken in should be significantly better sounding. We will see...
Mainly decided to go with the 18 as I plan to get the Volant intake and move some air, as well as since we can't tune the 2013s with 8 speed yet I don't want that MDS kick on/off to annoy me...
18" seems to be the middle ground for all.
Something I'm considering as well
