Hello Repsol_NSR, welcome to the Forum.
Not trying to be pushy, but we have a new Marketplace opening imminently, and will have some nice carbon cans that are a direct fit to the stock system!
Cans on an MC21 will give you a very slight increase in performance, but more than anything they look nice and weigh significantly less than stock - which is always a good thing!
Watch this space!
