Hello guys,

I'm looking to buy one of the 3 downpipes. AR Catted High Flow Cats, Evolution Racewerks High Flow Catted, or M5 Downpipes. I have heard but would also like to get clarification if it's true but the M5 downpipes on a 2011 550i would be the best downpipes for quality, performance, and keeping it catted.

If anyone has more insight please let me know. I'm looking for the best performance I can get out of my 550i.

M5 down pipes are highly restrictive and don't see how they would make more power over the stock 550 down pipes as they are similar design. Only 1 member claims performance but has no proof to back up the claims.
