FMIC prices vary significantly. Price difference between ETS and VRSF are huge..
VRSF $400 - from the pic looks like good quality product, 5" inch is direct bolt-on with only clamp replacement required.
ETS are starting at $695 for 5", and $175 additional for 7"
Than there is Active Autowerke, also close to $700
So what are the differences? If we say they are all the same, or close to being same, what do I need to look at to justify the additional costs? I have no problem speding $400 extra for quality product, just want to be able to justify the additional costs. What are the things I look out for?
