I personally like the body shape of my X5 compared to the new ones and they also gained almost 500lbs over the E53 so I think I'm going to plug away with the bolt-ons. Aside from having round tips vs oval like the 4.6, do you really think there's that much difference really between Dinan exhaust and the factory exhaust? I cut the silencer out and replaced it with an 'X' pipe so it sounds better and probably less restrictive. Also, since I had the exhaust replaced on insurance due to getting rear ended last year, it's still brand new.
