here are some quick pics. i'll post more after a wash
one pic had the new tips vs the old smaller tips to show the difference. used the full m5 exhaust all the way up to the downpipes (which they had to modify to fit). even the guys at the shop were surprised on how mean this thing sounds. 100x's better sounding with no drone at all. I'll try to get sound clips by the end of the week.
quick vid of the car warming up this morning.
phone recording when inside the car. Some cruising and some acceleration. cops were out so didn't want to press my luck :lol:
ok here we go, looks like you changed out the rear diffuser, yes, no. what mods did installers have to make to the vehicle and or the exhaust system. i am wanting to do something similar with my 2013, 550i xdrive. looks and sounds gr8888888888888t!!!!!!!!
I know about the diffuser needing to be changed but very interested on other modifications that had to be done to make it work let us know? I am doing this the second I can find a M5 exhaust were did you find yours?
Also was told most of the other pipe is the same except for the mufflers.

the piping is larger at 3" but pretty much the same besides that. the only part that was different was the connection to the downpipes. the shop just modified that piece to get it to bolt up.
Damn sweet. I had planned on getting the 550 diffuser and just installing quad tips which I like the quad tip look much better. I always thought about the m5 diffuser instead which is painted the same color as the car. I feel it makes the rear look more aggressive than a diffuser painted another color which makes the rear just look to small and less aggressive. The did the m5 diffuser install pretty simple or you had to have some work done to it?
m5 diffuser was a bit of a pain to get on because i have the CA. We had to trim a plastic piece off the bumper and double side tape the CA sensors to the body of the car.

u didnt like the ghetto muffler hack set up u did on ur 550:rofl:
sorry i couldnt resist! we told u back in the day an 80k car deserve a real exhaust job

sweet! I live right over the border in PA and am strongly thinking about giving those guys a call to get this done. If there is anyone else in the area that is interested, perhaps we get a group going?
to mount the m5 exhaust its ideal as it lines right up. if not they would need to modify the mufflers to fit the stock m sport diffuser. there is plenty of room so shouldn't be a hard adjustment. they can build you a custom full exhaust as well for around the same price if you wanted a louder setup
That sounds GREAT! I've been debating on getting the Dinan performance exhaust on my 550, but I have no idea what it sounds like. I wonder if it's similar to yours. The price sure isn't
I been thinking about putting this exhaust on my '13 528i xDrive. If I get the same rear diffuser as the one you got, do you know if it would fit my car? Or would I need a whole new bumper? I'm curious because the stock 528xi bumper is not cut out for dual exhaust; it only has one opening on the left side for the exhaust. Any insight would be appreciated!
the m5 diffuser will only fit your car if you have the m-sport package rear bumper. It won't fit a regular 528 bumper. you can probably source a decent m5 rear bumper on ebay or something
