That's what I thought it was (2.5"). Hmm, maybe I'll send out a bunch of fitment emails to multiple suppliers and see how their responses compare. I really hope it's just a drop in replacement like the s-tune midpipe. 3" vs 2.5" should make a difference for sure in sound and hopefully more HP/TQ too.
