Hello Mod Fanatics,
I need your brutal honesty and opinions.
I have a titanium silver 530i. The OEM Mtech, M5 trunk finisher and RD Sport Trunk Spoiler have been installed for a few years now. I want to go quad and having mixed feelings about which would look better on my current set up.
Please check out the pics and share your opinions, experiences, thoughts, etc.
Thank you in advance!

Honest opinion: the one in the first picture looks much better than the others.
Brutally honest opinion: you don't have an M5. reconcile with that fact. keep the setup that you have.

Here are a few more pics. It seems like the best exhaust tips for the Hamann diffuser is 90mm (3.5"). Otherwise, it would not look "best" due to its surrounding space/gaps.
I am still on the fence on my decision due to insufficient feedbacks.

The Hamann diffuser is too busy and kind of ugly in my opinion. I had an OEM M5 rear bumper on my old 530, and a custom quad setup. I did NOT have any M badges, LOL.
Do it the right way and buy a used M5 bumper on eBay (around $500) and have it panted (around $300). Its a direct bolt on (DIY). I did that on my 2008 550. Looks killer! No M5 badge. Lol.

The Hamann came available and cheap. I think I might be able to make it work (subjectively?). However, for the love of my BMW (Beautifully Made Woman), I am not sure if I would be happy looking at her new a@@ each day.

For the moment, I think I might just stay single (exhaust).
Thanks for the inputs, gents. And please excuse the lame metaphor.

I like the MTech better but the other looks ok as well. I like it a better from the side profile rather than the rear. I actually just received the dual MTech diffuser that i had ordered and have everything ready to get the dual exhaust installed except for time. I imagine this will take place in he next three weeks. Work is just eating up too much of my free time at the moment.
