I'm thinking about putting the magnaflow 4 inch dual tip muffler on my 330i but I might run into some problems.. the oem exhaust pipes are 3 inch and the inlet size is 2.25 inches that's a pretty big gap from 3inches.. What I was thinking about doing is buying a reducer that would go into the the oem pipe and convert the last foot or two into 2.25. What do you guys think I need some help to pull this off. Thanks. Part number is 14807. If you tHe any ideas how to get this setup to work, share it
