What intake did you get? I've been looking for one

everything is possible. You just need to be creative with y-pipe and the "bucket" on the right side.

+1 on the intake. I used AFE pro-dry drop-in air filter. Happy with the results!

If you're going for a louder exhaust, don't go for 550i mufflers. You're stock exhaust only has 1 muffler, whereas the 550i has two. The mufflers are also huge because they have to silence a 4.4 liter V8 engine.

On the other hand, the M5 mufflers are very small and have very little packing inside. That's going to be your best bet, if you choose a OEM option.

I believe the stock M5 piping is 3 inches. An exhaust shop can use pipe reducers or just widen an exhaust pipe to match up with the M5 piping.

Here is an example of a reducer. I'm not sure what size piping the 528 has but once you find the right size, you can purchase.
