I bought the magnaflow early on as much for sound as anything. Bought it as a group buy for very little. At first, it has a small drone around 200 rpms for about 500 miles but has since become minimal and completely absent cruising on the higway. Car sounds great but keep in mind it is a 3.0 with only one unit. At the last Homecoming many folks came up and asked me what exhaust I had. If $$ were no issue, go with a Supersprint. You'd be amazed how much weight you reduce by changing out the OE unit which still sits in my attic. On an M, there are more criticism of the sound. I did not remove the resonator which is a blessing now as it would knock me out of my current autocross class, STR. Most of my mods which are many were afterwards.
Where are you in Texas? I'm in Lubbock. I have a hard top (Titanium Silver) in good shape (one chip, and a small scratch) that I might have to sell when I move. I don't want to sell it unless I have to, but keep in touch and if you can't find one and I decide to sell, maybe we can work something out.
