Just figured I'd put this up for the 3.0i guys. I installed & can conclude later e53 N62 4.4L mufflers are a direct fit for e53 3.0i. My X5 is a 2003 3.0i manual trans pre-facelift model, I knew pre-facelift M62 4.4/4.6i mufflers are direct fit but wasn't sure on later N62 4.4i, took the chance on them.
Very quiet though not much of a difference from stock & this is with headers(no cats) installed. Quad tips look nice though.
Might cut open the mufflers & remove baffling inside then weld them closed at a later date.
