Can someone please tell me this info? I have not researched into this at all yet - I have 2008 X5 with N52 engine and someone stole part of the exhaust from the header down to cutting just past the cats about to a location distance of approximately under the front passenger seat! Yes it sucks. So I have a 2003 X5 with M54 engine. It was hit years ago so I keep it for parts. Will the header and the needed exhaust fit and attach on to the 2008? I can do the work to fabricate ? Thank you!!!
