There is nothing wrong w/ the M5 muffler swap, it's a matter of need and function. For most people on here, the stock 550 exhaust is way to quiet as it's dead silent, and they want a little more sound/volume, or which the M5 mufflers do the trick. They're not looking for radically loud exhaust, or obsessive about performance gains.
The reason M5 guys swap exhaust is because they want more sound than they already have. The performance gains of exhausts on an M5 are minimal, less so than on a 550. Also, more people buy M5 that are performance drivers than that which buys a 550, on average.

Yes the performance gains for a 550 on a exhaust is much greater then a m5. m5 coming with 3 inch piping and all.
I guess to each their own man.
I can only tell you my personal opinion, which is paying 1k for a m5 muffer swap parts and labor for just sound isn't really something I can mentally justify.
with a custom built xpipe and m5 mufflers / tips etc your spending even more.
I rather just have a full system. designed for the car. For around the same price.. but there is nothing out .. and what is out is for the 2011-13 and prices are INSANE.
