Hello gents. I have a 2006 530xi with front m5tech and mtech sides. I'm really thinking of pulling the trigger on a rear bumper. But really torn between the 2. Im really digging the m5 rear but not sure how difficult to get a quad set up on my xi. I know that the xi is different because of were the gas tanks sit I've passed up on a few quad exhaust on the forums for this same reason. So what are my options on running a quad set up? I seen umnitza has one for $800 but it's that my only option? Thanks

 

Here are a few discussions that have been posted about this topic:

Quad exhaust on an xi - Has anybody done it? - Bimmerfest - BMW Forums

I am in the same boat as you are with regard to the xi.

 

Thanks u brother
