I've recently purchased a downpipe that I'm gonna install here shortly. I read really good walkthroughs by both Perrin and TXS. In the TXS they mention you need a special tool to remove the rear 02 sensor. They specifically state a subaru approved one.
Is this an overkill step. Guys that have done this - ladies too if you are reading - is this a non-issue.
Thanks for your insights in advance.
P.S. I'm beyond excited to kiss two cats goodbye here this month with my new downpipe. heh.
