E60I

Hi guys,

I hope to be able to make a decision today. If any of you can answer the following questions, please share your knowledge.

Regarding to the Umnitza aftermarket M5 rear bumper installation, is it a direct fit to my existing side and rear bumper brackets??? Or do I have to remove the side brackets and use zip ties to keep the sides bumpers together? Do I need to trim any of my existing parts to get the bumper to fit?

Here is a link to Umnitza quad exhaust and not so straight, middle, bottom bumper part (as a reference to my questions):


Matt (Sales Rep at Umnitza) stated that the middle, bottom part of the bumper does not look straight because some people don't install the battery cover "that comes with bumper they sell". My battery is on the passenger side. How is the middle battery cover going to fit the middle, bottom of the Umnitza rear bumper?

As for the umnitza exhaust system (for E60, 5 Series), do I need to buy additional mounting parts to install it on my 2006 BMW 530i? I believe there is a cover to keep the battery from getting wet (during heavy rain and so forth...), is it still usable if the exhaust is installed on the passenger side?

When you answer the questions, please keep in mind that I currently have an OEM M-Tech rear bumper on right now.

Thank you in advance your help! :-)
