Price depends on where you order it and from whom. In US it can be as cheap as 300 USD, in Europe can be a bit more than 400 plus shipping. Try not to order from official BMW dealer if you don't want to pay more.
I figured out that it is relly expensive to ship midpipes to Russia, so I got just 1 way - yo go with n55 midpipes which I can find here... I found it for about $500 and try to find it cheaper through my friend in the dilership
So if I undestood I will have the good full bolt-on for the st.1 and I think it will be stable and reliable)
Tnx guys! On spring. after the installation I will write down a lil review on my mods!
