Went in a lot easier than the oem came out. Fits perfect. Nice tone paired with m exhaust and a muffler delete. CEL rarely comes on because my commute is pretty short. Smell in the cabin is barely present. Mostly after I floor it and then have to sit at a red light. Car installed on is an 18 540xi m package.

I purchased this down pipe for my 2019 G05 x5 m40ixdrive. Fitment was spot on. Welds and quality were good. My only gripe is; I wish a gasket was included or add to the product description that it is not. Thanks for a quality product at a reasonable price point.
