Recommendation for downpipes on e71 x6m

[elmasry17]

Hello everyone!

I need recommendation on which downpipe to install on 2012 e71 x6m. I already have velos stage 1 installed and wanted to upgrade to stage 2 but velos told me i need to install downpipe before upgrading to stage 2. I prefer catted so I don't get check engine light on. Any recommendations from experience which downpipe catted to install and not crazy expensive. I saw vrsf for $500 and active for 3k which is a bit out of my budget.

Thank you all
