So i recently ran into some extra cash so I think im gonna go with a 2 brothers pipe , can anyone out there tell me what the difference between a (m-2 and a m-5). i have a 2006 f4i and just not sure wich would be the best choice. thanks

 

The M-5 is a slightly bigger pipe than the M-2.

 

I was in the same situation as you and just ordered the carbon fibre M-2, i should get it this friday, i will post pics up as soon as i get it installed on saturday probably.

 

M-2



M-5


There's the difference, just in case you wanted detailed information.
