Went to the boneyard with a friend removed a rusty looking Dinan Exhaust which he paid $250 for. Went back to his house refurbished the Dianan exhaust with a series of wet sand/polishing techniques. Used 400,800,1500 and 2000 to wet sand off of the rust and restore original luster of the Dinan. looks like new.

I know a number of you think the Dinan parts are overpriced but the quality construction of this exhaust is an illustration of how well built these components are. All stainless steel construction allowed for the refurbishing process to take place. Had this been chrome on steel it would have rotted through. Did I mention how awesome sounding the Dina exhaust is on the X5 4.8is. Glorious!!!!
