Had it on my coupe and recently upgraded to the Akra Evo system.
83mm Quad Tips were a tad bit shorter since they were E90 application, but it wasn't too bad for anyone considering on purchasing it for their E92. Can easily be extended for $100-150 depending on where you go.
Has just under 5k miles usage. Excellent shape, could use a good polish, although I might do that myself for the buyer.
$1,800 picked up in SoCal.
