I was browsing mufflers on the magnaflow website, decided to check up-coming cat-back and I found they are coming out with one for the R56. I already have them on a custom set up on my PW R56, but with their sound, I would definitely buy their cat-back for my MY/B R56.

check it out for yourselves:

I also have a custom set up w/ a 5x8 muffler on my BMW. Very deep, throaty note to it.

Good lord though, $918?! It better be good.

 

ohhh I didn't see the price. I guess I will be going for another custom set-up
