I bought these from here for my X (2002 X5, 3.0i) but they don't fit. These are OEM BMW These are only for a 3.0si. I just want to make that clear. The inner diameter is 2.75" and will receive a 2.5" tailpipe. This will fit a 3.0i if you do a little bit of work. These are 2.75" on the short side and 4.75' on the high side. I would like $50 shipped for both, will entertain reasonable offers...
The guy who had these said he installed them and ran them for 50miles, before he upgraded his whole exhaust system
