Just out of curiosity, has anyone used these? They are substantially more than the spacers without the catalyst and I don't want to spend $120 on a set unless I hear something about them. I used a regular O2 spacer on my GTI's test pipe and it worked fine with no MIL lamp and stock tune but I know each car is different and sometimes they don't work on certain cars. I noticed they offered ones with a mini catalyst and was wondering if it would keep the MIL light off with the stock tune for inspection and/or the off chance I find a dealer that will look past my headers if I take it in.
