Yea, they started to drop prices on E9x parts.
The M performance exhaust for e90 is now $2300 for the rear section. I remember when MSRP was $4000 in 2010-2011. The alcantara flat bottom with Blue stripe 6MT steering wheel is now selling for $680, I remember it being a lot more before. Either way, E90 CF spoiler is now $336 shipped vs aftermarket ones being around $200. I'll pay the extra $100 more.
