I just had the Dinan exhaust installed on my car today and the fit was perfect. Dinan has not updated their website yet but they just began shipping. I have the Maddad mid pipe which deletes the two mid pipe cats and replaces them with staggered silencers. The sound of the exhaust is fantastic, the drone is almost none existent and the pull from low revs is better and especially at the top end. This is my second Dinan exhaust, I had one on my 2008 335i. I also have the Dinan Stage 2 ecu tune. For $2,000 for the exhaust, I think the price is very competitive and and the look and performance is fantastic.
