Great Service
Your service is great but I would like to correct something. Your so-called Converter is Not a Converter but it is called Resonators.. A Converter comes before the two, on the exhaust system. I returned the Resonators because they were not the problem with my car. The problem was two oxygen sensors gone bad. I will definitely keep your company in mind for another order, in the future.

Goodd price. No problems so far.
Installed it about 6 months ago. It hasn't had any problem since installation so far.

It does not come with the replacement attachment bolts which will most likely be needed since the bolts on the old catalytic converter will shear off during disassembly. Recommend getting the bolts from Subaru since the rear bolts are shouldered and should to be a specific length.

Also, make sure to tighten the bolt that is installed on the cat converter for the third sensor provision. It came installed on the pipe but it came loose and flew off not too long after it was installed.

BEST ANSWER: Yes it did fit my 2000 Subaru outback with a standard transmission
however I did not install it myself so not sure how much work went onto fitting it. The shop I took it to did not mention any problems with install, only said a couple bolts were ruined from rusting out.
