Looks better though:-)

Is that a magnaflow muffler?

No mate. Its a skytune rear box and tips. No drone, just a great sound when you put your foot down

Are you willing to admit that a quad exhaust set-up (at least on the V8 models) can provide gains on the e60?

After reading your post, it seems to imply that you're gonna lose power if you install a quad.

Custom Quad diffuser out of an oem mtech rear, with custom staggered tips, removed the oem mufflers and used two magnapacks. Just so you can get some ideas!

We've had 3 cars with dynos now that have shown power gains with our Quad setup.
I'm not sure where the power loss is on other quad setups but 3 cars out of 3 for the 530 have shown gains.

We've thus far had 2 cars install on a 550i but no Dynos yet.
